Perl Language Install Perl modules via CPAN cpanminus, the lightweight configuration-free replacement for cpan
Example
Usage
To install a module (assuming cpanm is already installed):
cpanm Data::Section
cpanm ("cpanminus") strives to be less verbose than cpan but still captures all of the installation information in a log file in case it is needed. It also handles many "interactive questions" for you, whereas cpan doesn't.
cpanm is also popular for installing dependencies of a project from, e.g., GitHub. Typical use is to first cd into the project's root, then run
cpanm --installdeps .
With --installdeps it will:
- Scan and install configure_requires dependencies from either
- META.json
- META.yml (if META.json is missing)
- Build the project (equivalent to
perl Build.PL), generating MYMETA files - Scan and install requires dependencies from either
- MYMETA.json
- MYMETA.yml (if MYMETA.json is missing)
To specify the file 'some.cpanfile', containing the dependencies, run:
cpanm --installdeps --cpanfile some.cpanfile .
cpanm Installation
There are several ways to install it. Here's installation via cpan:
cpan App::cpanminus
cpanm Configuration
There is no config file for cpanm. Rather, it relies on the following environment variables for its configuration:
PERL_CPANM_OPT(General cpanm command line options)export PERL_CPANM_OPT="--prompt"# in .bashrc, to enable prompting, e.g.setenv PERL_CPANM_OPT "--prompt"# in .tcshrc
PERL_MM_OPT(ExtUtils::MakeMaker command line options, affects module install target)PERL_MB_OPT(Module::Build command line options, affects module install target)
