我在 Windows 生产盒上安装了草莓 perl（v.5.16.3）。我假设很多个月前，有人将它安装在 C: 驱动器上，然后将其移动到 D:。我不知道，我不在那里，但是它工作正常，除非我尝试安装模块。使用 cpanm 只是将模块扔到 C: 驱动器上。不好。@INC 不会去那里，管理员也不希望那里有任何东西。我需要它们在 D: 上使用 Perl。

所以，我尝试使用 cpan 并更改目录：

cpan> o conf mbuildpl_arg "--install_base D:/strawberry/perl"
    mbuildpl_arg       [--install_base D:strawberryperl]
commit: wrote 'D:\strawberry\perl\lib/CPAN/Config.pm'

cpan> o conf makepl_arg "PREFIX=D:/strawberry/perl"
    makepl_arg         [PREFIX=D:/strawberry/perl]
commit: wrote 'D:\strawberry\perl\lib/CPAN/Config.pm'

cpan> install Email::Simple

它在 D:/strawberry/perl/lib 中安装了 Email Simple - 并不完美，但它可以工作。伟大的！其他一些人也经历了同样的事情。去安装模块::运行时

cpan> install Module::Runtime

这在 D:/strawberry/perl/lib/perl5 中。嗯？好的，不完美，但我的@INC 包括 D:/strawberry/perl/lib 所以这应该不是问题，对吧？去安装 MooX::Types::MooseLike::Base

cpan> install MooX::Types::MooseLike::Base

不会安装。这是cpan barf：

cpan> install MooX::Types::MooseLike::Base
Running install for module 'MooX::Types::MooseLike::Base'
Running make for M/MA/MATEU/MooX-Types-MooseLike-0.29.tar.gz

而且这个错误重复了几次，所有的测试都失败了，等等。

所以，问题....

(1) 我需要做什么才能将 Module::Runtime 放在正确的位置？我之前更改目录的尝试对某些人有效，但对这个无效。我更喜欢 D:\strawberry\perl\site\lib - 因为 cpanm 似乎会将它的模块放在那里，但 D:\strawberry\perl\lib 也可以正常工作。

如果我们修复数字 (1) 这并不重要，但我很好奇是否有人有答案：

(2) 为什么当Module::Runtime 位于@INC 的子目录之一时，cpan 找不到？

所以我知道一个答案是在正确的位置重新安装草莓，但这是一个持续运行 Perl 脚本并且没有停机时间的生产盒，所以不，这不是一个选项。无论如何，他们不会允许我这样做。

在此先感谢您的帮助。

您为使用 ExtUtils::MakeMaker 作为其安装程序的模块提供的参数与您为使用 Module::Build 作为其安装程序的模块提供的参数不一致。选择一个方案并始终如一地使用它。

o conf makepl_arg "INSTALL_BASE=D:/strawberry/perl_modules"
o conf mbuildpl_arg "--install_base D:/strawberry/perl_modules"

不要忘记告诉 Perl 在哪里寻找模块。

set PERL5LIB=D:/strawberry/perl_modules/lib/perl5

虽然这可以解决您的直接问题，但您解决潜在问题的方法并不是最好的。只需清除这些值即可将模块安装在正确的位置。

o conf makepl_arg ""
o conf mbuildpl_arg ""
set PERL5LIB=

还要确保不要覆盖 env vars 中的安装位置。

set PERL_MM_OPT=
set PERL_MB_OPT=

最后，您可能需要检查Config.pm并Config_heavy.pl需要C:将其更改为D:.
