安装缺少的 Perl 模块的最简单方法是什么？

Question

I get this error:

Can't locate Foo.pm in @INC

Is there an easier way to install it than downloading, untarring, making, etc?

Answer 1

On Unix:

usually you start cpan in your shell:

# cpan

and type

install Chocolate::Belgian

or in short form:

cpan Chocolate::Belgian

On Windows:

If you're using ActivePerl on Windows, the PPM (Perl Package Manager) has much of the same functionality as CPAN.pm.

Example:

# ppm
ppm> search net-smtp
ppm> install Net-SMTP-Multipart

see How do I install Perl modules? in the CPAN FAQ

Many distributions ship a lot of perl modules as packages.

• Gentoo: category dev-perl
• Debian: apt-cache search 'perl$'

You should always prefer them as you benefit from automatic (security) updates and the ease of removal. This can be pretty tricky with the cpan tool itself.

For Gentoo there's a nice tool called g-cpan which builds/installs the module from CPAN and creates a Gentoo package (ebuild) for you.
