我遇到了以下问题，我不知道是什么介绍了它，但是 Mac 上的 perl 包含路径总是一场噩梦；

我在 /opt/local/lib/perl5/site_perl/5.12.4/darwin-multi-2level/HTML CPAN 中有 HTML::HeadParser 在此之前已经工作了几个月。

如何更改@INC 系统范围内的内容，以便 IDE (Eclipse) 和 CPAN 都知道如何查看。我一直在对 Makefile.PL 进行全局文件搜索，使用诸如sudo find / -name "*.PL" | xargs grep "Makefile"在各种情况下尝试找到它并尝试此建议等命令，但到目前为止没有成功。（哦，我多么讨厌这个操作系统 :)）

我不知道确切的解决方案，可能这个链接会有所帮助..

Perl 的@INC 是如何构造的？（又名影响 Perl 模块搜索位置的所有方法是什么？）

如果$Config{usesitecustomize}已定义，您可以查找sitecustomize.plat $Config{sitelib}\\sitecustomize.pl。见perlrun。

%Config变量告诉你 perl 是如何编译运行的，所以需要重新编译来改变它。

除此之外，您还可以更改任何正在运行的通用登录脚本——如果有的话——以便环境变量PERL5LIB包含你的路径——我相信环境变量PERLLIB仍然可以正常工作。
