I have started using perlbrew and installed perl-5.12.2.
我已经开始使用perlbrew并安装了perl-5.12.2。
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).
我知道我需要重新安装我的CPAN模块，所以我切换到我的新Perl版本（perlbrew开关perl-5.12.2和hash -r），验证交换机是否成功（perl -v）然后尝试安装一些模块（ File :: Copy ::使用cpan递归。但是，cpan说`File :: Copy :: Recursive是最新的（0.38）。
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.
当我使用这个模块启动一个Perl脚本时，它会在@INC中找不到File / Copy / Recursive.pm ...（显示许多perl-5.12.2位置）。当我切换回我的'普通'Perl（perlbrew off）时，脚本运行正常。
Any suggestions? Perhaps CPAN does not work well with perlbrew?
有什么建议么？也许CPAN与perlbrew不兼容？

After installing perlbrew you could install cpanm through this command:
安装perlbrew后，您可以通过以下命令安装cpanm：
perlbrew install-cpanm
Otherwise you will need to install cpanm manually each time you switch your Perl version on perlbrew. With this command just once.
否则，每次在perlbrew上切换Perl版本时，都需要手动安装cpanm。使用此命令只需一次。

Everything should be working fine with "cpan" as well as "cpanm", that is: when switching perl with perlbrew, cpan sees the installed modules of the version you use.
一切都应该与“cpan”以及“cpanm”一起正常工作，即：当用perlbrew切换perl时，cpan会看到你使用的版本的已安装模块。
While it's true that cpanm is the recommended tool to use with perlbrew, cpan allows for test reporting so that is what I always use.
虽然cpanm是与perlbrew一起使用的推荐工具，但cpan允许进行测试报告，这是我一直使用的。
