NAME
       cpanm - get, unpack build and install modules from CPAN
SYNOPSIS
         cpanm Test::More                                 # install Test::More
         cpanm MIYAGAWA/Plack-0.99_05.tar.gz              # full distribution path
         cpanm http://example.org/LDS/CGI.pm-3.20.tar.gz  # install from URL
         cpanm ~/dists/MyCompany-Enterprise-1.00.tar.gz   # install from a local file
         cpanm --interactive Task::Kensho                 # Configure interactively
         cpanm .                                          # install from local directory
         cpanm --installdeps .                            # install all the deps for the current directory
         cpanm -L extlib Plack                            # install Plack and all non-core deps into extlib
         cpanm --mirror http://cpan.cpantesters.org/ DBI  # use the fast-syncing mirror
COMMANDS
       (arguments)
           Command line arguments can be either a module name, distribution
           file, local file path, HTTP URL or git repository URL. Following
           commands will all work as you expect.
               cpanm Plack
               cpanm Plack/Request.pm
               cpanm MIYAGAWA/Plack-1.0000.tar.gz
               cpanm /path/to/Plack-1.0000.tar.gz
               cpanm http://cpan.metacpan.org/authors/id/M/MI/MIYAGAWA/Plack-0.9990.tar.gz
               cpanm git://github.com/miyagawa/Plack.git
           Additionally, you can use the notation using "~" and "@" to specify
           version for a given module. "~" specifies the version requirement
           in the CPAN::Meta::Spec format, while "@" pins the exact version,
           and is a shortcut for "~"== VERSION"".
               cpanm Plack~1.0000                 # 1.0000 or later
               cpanm Plack~">= 1.0000, < 2.0000"  # latest of 1.xxxx
               cpanm Plack AT 0.9990                 # specific version. same as Plack~"== 0.9990"
           The version query including specific version or range will be sent
           to MetaCPAN to search for previous releases. The query will search
           for BackPAN archives by default, unless you specify "--dev" option,
           in which case, archived versions will be filtered out.
           For a git repository, you can specify a branch, tag, or commit SHA
           to build. The default is "master"
               cpanm git://github.com/miyagawa/Plack.git AT 1.0000        # tag
               cpanm git://github.com/miyagawa/Plack.git@devel         # branch
       -i, --install
           Installs the modules. This is a default behavior and this is just a
           compatibility option to make it work like cpan or cpanp.
       --self-upgrade
           Upgrades itself. It's just an alias for:
             cpanm App::cpanminus
       --info
           Displays the distribution information in
           "AUTHOR/Dist-Name-ver.tar.gz" format in the standard out.
       --installdeps
           Installs the dependencies of the target distribution but won't
           build itself. Handy if you want to try the application from a
           version controlled repository such as git.
             cpanm --installdeps .
       --look
           Download and unpack the distribution and then open the directory
           with your shell. Handy to poke around the source code or do manual
           testing.
       -U, --uninstall
           EXPERIMENTAL: Uninstalls the modules. Will remove the distribution
           files from your library path using the ".packlist" file.
           When used with "-l" or "-L", only the files under the local::lib
           directory will be removed.
           NOTE: If you have the "dual-life" module in multiple locations
           (i.e. "site_perl" and "perl" library path, with perl 5.12 or
           later), only the files in "site_perl" will be deleted.
           If the distribution has bin scripts and man, they will be kept in
           case the core installation still references that, although there's
           no guarantee that the script will continue working as expected with
           the older version of .pm files.
       -h, --help
           Displays the help message.
       -V, --version
           Displays the version number.
OPTIONS
       You can specify the default options in "PERL_CPANM_OPT" environment
       variable.
       -f, --force
           Force install modules even when testing failed.
       -n, --notest
           Skip the testing of modules. Use this only when you just want to
           save time for installing hundreds of distributions to the same perl
           and architecture you've already tested to make sure it builds fine.
           Defaults to false, and you can say "--no-notest" to override when
           it is set in the default options in "PERL_CPANM_OPT".
       --test-only
           Run the tests only, and do not install the specified module or
           distributions. Handy if you want to verify the new (or even old)
           releases pass its unit tests without installing the module.
           Note that if you specify this option with a module or distribution
           that has dependencies, these dependencies will be installed if you
           don't currently have them.
       -S, --sudo
           Switch to the root user with "sudo" when installing modules. Use
           this if you want to install modules to the system perl include
           path.
           Defaults to false, and you can say "--no-sudo" to override when it
           is set in the default options in "PERL_CPANM_OPT".
       -v, --verbose
           Makes the output verbose. It also enables the interactive
           configuration. (See --interactive)
       -q, --quiet
           Makes the output even more quiet than the default. It only shows
           the successful/failed dependencies to the output.
       -l, --local-lib
           Sets the local::lib compatible path to install modules to. You
           don't need to set this if you already configure the shell
           environment variables using local::lib, but this can be used to
           override that as well.
       -L, --local-lib-contained
           Same with "--local-lib" but with --self-contained set.  All non-
           core dependencies will be installed even if they're already
           installed.
           For instance,
             cpanm -L extlib Plack
           would install Plack and all of its non-core dependencies into the
           directory "extlib", which can be loaded from your application with:
             use local::lib '/path/to/extlib';
       --self-contained
           When examining the dependencies, assume no non-core modules are
           installed on the system. Handy if you want to bundle application
           dependencies in one directory so you can distribute to other
           machines.
       --mirror
           Specifies the base URL for the CPAN mirror to use, such as
           "http://cpan.cpantesters.org/" (you can omit the trailing slash).
           You can specify multiple mirror URLs by repeating the command line
           option.
           You can use a local directory that has a CPAN mirror structure
           (created by tools such as OrePAN or Pinto) by using a special URL
           scheme "file://". If the given URL begins with `/` (without any
           scheme), it is considered as a file scheme as well.
             cpanm --mirror file:///path/to/mirror
             cpanm --mirror ~/minicpan      # Because shell expands ~ to /home/user
           Defaults to "http://www.cpan.org/".
       --mirror-only
           Download the mirror's 02packages.details.txt.gz index file instead
           of querying the CPAN Meta DB. This will also effectively opt out
           sending your local perl versions to backend database servers such
           as CPAN Meta DB and MetaCPAN.
           Select this option if you are using a local mirror of CPAN, such as
           minicpan when you're offline, or your own CPAN index (a.k.a
           darkpan).
           Tip: It might be useful if you name these mirror options with your
           shell aliases, like:
             alias minicpanm='cpanm --mirror ~/minicpan --mirror-only'
             alias darkpan='cpanm --mirror http://mycompany.example.com/DPAN --mirror-only'
       --mirror-index
           EXPERIMENTAL: Specifies the file path to "02packages.details.txt"
           for module search index.
       --prompt
           Prompts when a test fails so that you can skip, force install,
           retry or look in the shell to see what's going wrong. It also
           prompts when one of the dependency failed if you want to proceed
           the installation.
           Defaults to false, and you can say "--no-prompt" to override if
           it's set in the default options in "PERL_CPANM_OPT".
       --dev
           EXPERIMENTAL: search for a newer developer release as well.
           Defaults to false.
       --reinstall
           cpanm, when given a module name in the command line (i.e. "cpanm
           Plack"), checks the locally installed version first and skips if it
           is already installed. This option makes it skip the check, so:
             cpanm --reinstall Plack
           would reinstall Plack even if your locally installed version is
           latest, or even newer (which would happen if you install a
           developer release from version control repositories).
           Defaults to false.
       --interactive
           Makes the configuration (such as "Makefile.PL" and "Build.PL")
           interactive, so you can answer questions in the distribution that
           requires custom configuration or Task:: distributions.
           Defaults to false, and you can say "--no-interactive" to override
           when it's set in the default options in "PERL_CPANM_OPT".
       --pp, --pureperl
           Prefer Pure perl build of modules by setting "PUREPERL_ONLY=1" for
           MakeMaker and "--pureperl-only" for Build.PL based distributions.
           Note that not all of the CPAN modules support this convention yet.
       --with-recommends, --with-suggests
           EXPERIMENTAL: Installs dependencies declared as "recommends" and
           "suggests" respectively, per META spec. When these dependencies
           fail to install, cpanm continues the installation, since they're
           just recommendation/suggestion.
           Enabling this could potentially make a circular dependency for a
           few modules on CPAN, when "recommends" adds a module that
           "recommends" back the module in return.
           There's also "--without-recommend" and "--without-suggests" to
           override the default decision made earlier in "PERL_CPANM_OPT".
           Defaults to false for both.
       --with-feature, --without-feature, --with-all-features
           EXPERIMENTAL: Specifies the feature to enable, if a module supports
           optional features per META spec 2.0.
               cpanm --with-feature=opt_csv Spreadsheet::Read
           the features can also be interactively chosen when "--interactive"
           option is enabled.
           "--with-all-features" enables all the optional features, and
           "--without-feature" can select a feature to disable.
       --configure-timeout, --build-timeout, --test-timeout
           Specify the timeout length (in seconds) to wait for the configure,
           build and test process. Current default values are: 60 for
           configure, 3600 for build and 1800 for test.
       --configure-args, --build-args, --test-args, --install-args
           EXPERIMENTAL: Pass arguments for configure/build/test/install
           commands respectively, for a given module to install.
               cpanm DBD::mysql --configure-args="--cflags=... --libs=..."
           The argument is only enabled for the module passed as a command
           line argument, not dependencies.
       --scandeps
           Scans the depencencies of given modules and output the tree in a
           text format. (See "--format" below for more options)
           Because this command doesn't actually install any distributions, it
           will be useful that by typing:
             cpanm --scandeps Catalyst::Runtime
           you can make sure what modules will be installed.
           This command takes into account which modules you already have
           installed in your system. If you want to see what modules will be
           installed against a vanilla perl installation, you might want to
           combine it with "-L" option.
       --format
           Determines what format to display the scanned dependency tree.
           Available options are "tree", "json", "yaml" and "dists".
           tree    Displays the tree in a plain text format. This is the
                   default value.
           json, yaml
                   Outputs the tree in a JSON or YAML format. JSON and YAML
                   modules need to be installed respectively. The output tree
                   is represented as a recursive tuple of:
                     [ distribution, dependencies ]
                   and the container is an array containing the root elements.
                   Note that there may be multiple root nodes, since you can
                   give multiple modules to the "--scandeps" command.
           dists   "dists" is a special output format, where it prints the
                   distribution filename in the depth first order after the
                   dependency resolution, like:
                     GAAS/MIME-Base64-3.13.tar.gz
                     GAAS/URI-1.58.tar.gz
                     PETDANCE/HTML-Tagset-3.20.tar.gz
                     GAAS/HTML-Parser-3.68.tar.gz
                     GAAS/libwww-perl-5.837.tar.gz
                   which means you can install these distributions in this
                   order without extra dependencies. When combined with "-L"
                   option, it will be useful to replay installations on other
                   machines.
       --save-dists
           Specifies the optional directory path to copy downloaded tarballs
           in the CPAN mirror compatible directory structure i.e.
           authors/id/A/AU/AUTHORS/Foo-Bar-version.tar.gz
           If the distro tarball did not come from CPAN, for example from a
           local file or from GitHub, then it will be saved under
           vendor/Foo-Bar-version.tar.gz.
       --uninst-shadows
           Uninstalls the shadow files of the distribution that you're
           installing. This eliminates the confusion if you're trying to
           install core (dual-life) modules from CPAN against perl 5.10 or
           older, or modules that used to be XS-based but switched to pure
           perl at some version.
           If you run cpanm as root and use "INSTALL_BASE" or equivalent to
           specify custom installation path, you SHOULD disable this option so
           you won't accidentally uninstall dual-life modules from the core
           include path.
           Defaults to true if your perl version is smaller than 5.12, and you
           can disable that with "--no-uninst-shadows".
           NOTE: Since version 1.3000 this flag is turned off by default for
           perl newer than 5.12, since with 5.12 @INC contains site_perl
           directory before the perl core library path, and uninstalling
           shadows is not necessary anymore and does more harm by deleting
           files from the core library path.
       --uninstall, -U
           Uninstalls a module from the library path. It finds a packlist for
           given modules, and removes all the files included in the same
           distribution.
           If you enable local::lib, it only removes files from the local::lib
           directory.
           If you try to uninstall a module in "perl" directory (i.e. core
           module), an error will be thrown.
           A dialog wil be prompted to confirm the files to be deleted. If you
           pass "-f" option as well, the dialog will be skipped and
           uninstallation will be forced.
       --cascade-search
           EXPERIMENTAL: Specifies whether to cascade search when you specify
           multiple mirrors and a mirror doesn't have a module or has a lower
           version of the module than requested. Defaults to false.
       --skip-installed
           Specifies whether a module given in the command line is skipped if
           its latest version is already installed. Defaults to true.
           NOTE: The "PERL5LIB" environment variable have to be correctly set
           for this to work with modules installed using local::lib, unless
           you always use the "-l" option.
       --skip-satisfied
           EXPERIMENTAL: Specifies whether a module (and version) given in the
           command line is skipped if it's already installed.
           If you run:
             cpanm --skip-satisfied CGI DBI~1.2
           cpanm won't install them if you already have CGI (for whatever
           versions) or have DBI with version higher than 1.2. It is similar
           to "--skip-installed" but while "--skip-installed" checks if the
           latest version of CPAN is installed, "--skip-satisfied" checks if a
           requested version (or not, which means any version) is installed.
           Defaults to false.
       --verify
           Verify the integrity of distribution files retrieved from PAUSE
           using CHECKSUMS and SIGNATURES (if found). Defaults to false.
       --report-perl-version
           Whether it report the locally installed perl version to the various
           web server as part of User-Agent. Defaults to true, and you can
           disable it by using "--no-report-perl-version".
       --auto-cleanup
           Specifies the number of days in which cpanm's work directories
           expire. Defaults to 7, which means old work directories will be
           cleaned up in one week.
           You can set the value to 0 to make cpan never cleanup those
           directories.
       --man-pages
           Generates man pages for executables (man1) and libraries (man3).
           Defaults to true (man pages generated) unless
           "-L|--local-lib-contained" option is supplied in which case it's
           set to false. You can disable it with "--no-man-pages".
       --lwp
           Uses LWP module to download stuff over HTTP. Defaults to true, and
           you can say "--no-lwp" to disable using LWP, when you want to
           upgrade LWP from CPAN on some broken perl systems.
       --wget
           Uses GNU Wget (if available) to download stuff. Defaults to true,
           and you can say "--no-wget" to disable using Wget (versions of Wget
           older than 1.9 don't support the "--retry-connrefused" option used
           by cpanm).
       --curl
           Uses cURL (if available) to download stuff. Defaults to true, and
           you can say "--no-curl" to disable using cURL.
           Normally with "--lwp", "--wget" and "--curl" options set to true
           (which is the default) cpanm tries LWP, Wget, cURL and HTTP::Tiny
           (in that order) and uses the first one available.
