使用perlbrew时如何安装CPAN模块? [英] How do I install CPAN modules while using perlbrew?

问题描述

我已经开始使用perlbrew并安装了perl-5.12.2.

I have started using perlbrew and installed perl-5.12.2.

我了解我需要重新安装CPAN模块，因此我切换到了新的Perl版本(perlbrew switch perl-5.12.2和hash -r)，验证了切换是否成功(perl -v)，然后尝试安装了某些模块(File::Copy::Recursive使用cpan.但是，cpan表示`File :: Copy :: Recursive是最新的(0.38).

I understand I need to re-install my CPAN modules, so I switched to my new Perl version (perlbrew switch perl-5.12.2 and hash -r), verified the switch was successful (perl -v) then tried installing some module (File::Copy::Recursive using cpan. However, cpan says `File::Copy::Recursive is up to date (0.38).

当我使用此模块启动Perl脚本时，它会大喊Can't locate File/Copy/Recursive.pm in @INC ...(显示许多perl-5.12.2位置).当我切换回我的普通" Perl(perlbrew off)时，脚本运行良好.

When I start a Perl script using this module, it shouts Can't locate File/Copy/Recursive.pm in @INC ... (showing many perl-5.12.2 locations). When I switch back to my 'normal' Perl (perlbrew off) the script runs fine.

有什么建议吗?也许CPAN在perlbrew下不能很好地工作?

Any suggestions? Perhaps CPAN does not work well with perlbrew?

推荐答案

安装perlbrew之后，您可以通过以下命令安装cpanm:

After installing perlbrew you could install cpanm through this command:

perlbrew install-cpanm

否则，每次在perlbrew上切换Perl版本时，都需要手动安装cpanm.只需使用此命令一次即可.

Otherwise you will need to install cpanm manually each time you switch your Perl version on perlbrew. With this command just once.
