When running, it requires only 10MB - of RAM. - - =head1 INSTALLATION - - There are several ways to install cpanminus to your system. - - =head2 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 C<cpanm> to your system without thinking about where to - install, and later upgrade. - - =head2 Installing to system perl - - You can also use the latest cpanminus to install cpanminus itself: - - curl -L http://cpanmin.us | perl - --sudo App::cpanminus - - This will install C<cpanm> to your bin directory like - C</usr/local/bin> (unless you configured C<INSTALL_BASE> with - L<local::lib>), so you probably need the C<--sudo> option. - - =head2 Installing to local perl (perlbrew) - - If you have perl in your home directory, which is the case if you use - tools like L<perlbrew>, you don't need the C<--sudo> option, since - you're most likely to have a write permission to the perl's library - path. You can just do: - - curl -L http://cpanmin.us | perl - App::cpanminus - - to install the C<cpanm> executable to the perl's bin path, like - C<~/perl5/perlbrew/bin/cpanm>. - - =head2 Downloading the standalone executable - - You can also copy the standalone executable to whatever location you'd like. - - cd ~/bin - curl -LO http://xrl.us/cpanm - 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 C<--self-upgrade> might not work for this. - - =head1 DEPENDENCIES - - perl 5.8 or later. - - =over 4 - - =item * - - 'tar' executable (bsdtar or GNU tar version 1.22 are rcommended) or Archive::Tar to unpack files. - - =item * - - C compiler, if you want to build XS modules. - - =item * - - make - - =item * - - Module::Build (core in 5.10) - - =back - - =head1 QUESTIONS - - =head2 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. - - =head2 But why a new client? - - First of all, let me be clear that CPAN and CPANPLUS are great tools - I've used for I<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. - - =head2 Zero-conf? How does this module get/parse/update the CPAN index? - - It queries the CPAN Meta DB site running on Google AppEngine at - L<http://cpanmetadb.plackperl.org/>. 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 L<http://search.cpan.org/>. - - Fetched files are unpacked in C<~/.cpanm> and automatically cleaned up - periodically. You can configure the location of this with the - C<PERL_CPANM_HOME> environment variable. - - =head2 Where does this install modules to? Do I need root access? - - It installs to wherever ExtUtils::MakeMaker and Module::Build are - configured to (via C<PERL_MM_OPT> and C<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 C<perl5> directory under your home - directory. To avoid this, run the script as the root user, with - C<--sudo> option or with C<--local-lib> option. - - =head2 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: - - =over 4 - - =item * - - Tests that require input from STDIN. - - =item * - - Tests that might fail when C<AUTOMATED_TESTING> is enabled. - - =item * - - Modules that have invalid numeric values as VERSION (such as C<1.1a>) - - =back - - These failures can be reported back to the author of the module so - that they can fix it accordingly, rather than me. - - =head2 Does cpanm support the feature XYZ of L<CPAN> and L<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 I<minus>, - right? - - If you need these features, use L<CPAN>, L<CPANPLUS> or the standalone - tools that are mentioned. - - =over 4 - - =item * - - Bundle:: module dependencies - - =item * - - CPAN testers reporting - - =item * - - Building RPM packages from CPAN modules - - =item * - - Listing the outdated modules that needs upgrading.
