我遇到了以下问题我不知道是什么介绍它但是perl包含Mac上的路径始终是一场噩梦;

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

如何更改@INC 系统范围 中的内容，以便IDE（Eclipse）和CPAN都知道如何查看。我一直在使用sudo find / -name "*.PL" | xargs grep "Makefile"等命令对Makefile.PL进行全局文件搜索以尝试查找并尝试this recommendation，但到目前为止还没有成功。（哦，我讨厌这个操作系统：））

Answer 1

我不知道确切的解决方案，可能这个链接会有所帮助..

How is Perl's @INC constructed? (aka What are all the ways of affecting where Perl modules are searched for?)

Answer 2

如果定义了$Config{usesitecustomize}，您可以在sitecustomize.pl查找$Config{sitelib}\\sitecustomize.pl。请参阅perlrun。

%Config变量告诉您perl如何编译运行，因此需要重新编译才能更改它。

除此之外，您还可以更改运行的任何通用登录脚本（如果有），以便环境变量PERL5LIB包含您的路径 - 我相信环境变量PERLLIB仍然有用。

添加到全局PERL @INC的路径，系统范围，而不是我的脚本，但是全局。在Mac上
