       App::cpanminus - get, unpack, build and install modules from CPAN


           cpanm Module

       Run "cpanm -h" for more options.


       cpanminus is a script to get, unpack, build and install modules from CPAN and does nothing

       It's dependency free (can bootstrap itself), requires zero configuration, and stands
       alone. When running, it requires only 10MB of RAM.


       There are several ways to install cpanminus to your system.

   Package management system
       There are Debian packages, RPMs, FreeBSD ports, and packages for other operation systems
       available. If you want to use the package management system, search for cpanminus and use
       the appropriate command to install. This makes it easy to install "cpanm" to your system
       without thinking about where to install, and later upgrade.

   Installing to system perl
       You can also use the latest cpanminus to install cpanminus itself:

           curl -L | perl - --sudo App::cpanminus

       This will install "cpanm" to your bin directory like "/usr/local/bin" (unless you
       configured "INSTALL_BASE" with local::lib), so you probably need the "--sudo" option.

   Installing to local perl (perlbrew)
       If you have perl in your home directory, which is the case if you use tools like perlbrew,
       you don't need the "--sudo" option, since you're most likely to have a write permission to
       the perl's library path. You can just do:

           curl -L | perl - App::cpanminus

       to install the "cpanm" executable to the perl's bin path, like

   Downloading the standalone executable
       You can also copy the standalone executable to whatever location you'd like.

           cd ~/bin
           curl -LO
           chmod +x cpanm
           # edit shebang if you don't have /usr/bin/env

       This just works, but be sure to grab the new version manually when you upgrade because
       "--self-upgrade" might not work for this.


       perl 5.8 or later.

       ·   'tar' executable (bsdtar or GNU tar version 1.22 are rcommended) or Archive::Tar to
           unpack files.

       ·   C compiler, if you want to build XS modules.

       ·   make

       ·   Module::Build (core in 5.10)


   Another CPAN installer?
       OK, the first motivation was this: the CPAN shell runs out of memory (or swaps heavily and
       gets really slow) on Slicehost/linode's most affordable plan with only 256MB RAM. Should I
       pay more to install perl modules from CPAN? I don't think so.

   But why a new client?
       First of all, let me be clear that CPAN and CPANPLUS are great tools I've used for
       literally years (you know how many modules I have on CPAN, right?). I really respect their
       efforts of maintaining the most important tools in the CPAN toolchain ecosystem.

       However, for less experienced users (mostly from outside the Perl community), or even
       really experienced Perl developers who know how to shoot themselves in their feet, setting
       up the CPAN toolchain often feels like yak shaving, especially when all they want to do is
       just install some modules and start writing code.

   Zero-conf? How does this module get/parse/update the CPAN index?
       It queries the CPAN Meta DB site running on Google AppEngine at
       <>. The site is updated every hour to reflect the latest
       changes from fast syncing mirrors. The script then also falls back to scrape the site

       Fetched files are unpacked in "~/.cpanm" and automatically cleaned up periodically.  You
       can configure the location of this with the "PERL_CPANM_HOME" environment variable.

   Where does this install modules to? Do I need root access?
       It installs to wherever ExtUtils::MakeMaker and Module::Build are configured to (via
       "PERL_MM_OPT" and "PERL_MB_OPT"). So if you're using local::lib, then it installs to your
       local perl5 directory. Otherwise it installs to the site_perl directory that belongs to
       your perl.

       cpanminus at a boot time checks whether you have configured local::lib, or have the
       permission to install modules to the site_perl directory.  If neither, it automatically
       sets up local::lib compatible installation path in a "perl5" directory under your home
       directory. To avoid this, run the script as the root user, with "--sudo" option or with
       "--local-lib" option.

   cpanminus can't install the module XYZ. Is it a bug?
       It is more likely a problem with the distribution itself. cpanminus doesn't support or is
       known to have issues with distributions like as follows:

       ·   Tests that require input from STDIN.

       ·   Tests that might fail when "AUTOMATED_TESTING" is enabled.

       ·   Modules that have invalid numeric values as VERSION (such as "1.1a")

       These failures can be reported back to the author of the module so that they can fix it
       accordingly, rather than me.

   Does cpanm support the feature XYZ of CPAN and CPANPLUS?
       Most likely not. Here are the things that cpanm doesn't do by itself. And it's a feature -
       you got that from the name minus, right?

       If you need these features, use CPAN, CPANPLUS or the standalone tools that are mentioned.
