Perl cpanm-L坏了吗？

根据手册

cpanm -L extlib Plack # install Plack and all non-core deps into extlib

因此，我尝试安装Parallel:：ForkManager，如下所示：

# cpanm -L extlib Parallel::ForkManager

我不明白的是，为什么它试图安装core deps，而手册页上显示的是非core deps。我真正的影响是FPM，它在-L标志下使用cpanm。由于此故障，我无法将CPAN包转换为RPM

# /usr/local/bin/cpanm --version
cpanm (App::cpanminus) version 1.7004 (/usr/local/bin/cpanm)

有没有人遇到过同样的问题/找到了解决方案？

我刚刚在CentOS 7.x的一个盒子上遇到了这个问题

我通过将

-L

切换到

-L

（小写L）来安装

ExtUtils:：MakeMaker

及其依赖项，然后切换回对我正在安装的其他模块使用

-L

，成功地解决了这个问题

更新：似乎

-l

技巧只有在您不了解相关模块的最新信息时才有效。在这种情况下，您需要使用

-l/path/to/install/to--force

ExtUtils:：MakeMaker安装在哪里（MakeMaker.pm的位置）？我想就是这样：$perldoc-l ExtUtils:：MakeMaker/usr/local/share/perl5/ExtUtils/MakeMaker.pm，它在您的sitelb目录中，而不是“核心模块路径”，所以没有找到。我怀疑是谁打包了你的perl，把核心模块放在了一个非核心的位置，做了一些不恰当的事情。谢谢你的回复。我不知道有一个叫做核心模块路径的东西，因为我把“核心deps”理解为核心模块，MakeMaker就是。让我玩一下MakeMaker.pm的路径，看看这是否会使事情向前发展。

-L

选项通过将库搜索路径限制为您指定的

local:：lib

加上perl的

privilibexp

和

archlibexp

路径来工作，这是预期安装核心模块的地方。
