升级后无法加载(并重新安装) Socket.pm

Question

我刚刚将Slackware64升级到14.1，并在其中找到Perl5.18。Socket.pm现在抱怨它是为另一个Perl版本编译的，这个版本是5.16。以下是错误：

Perl API version v5.16.0 of Socket does not match v5.18.0 at /usr/share/perl5/XSLoader.pm line 92.

不幸的是，即使使用Socket.pm，我也无法重新安装cpan。

据我所知，Socket.pm是一个Perl核心模块。所以，我认为它应该与Perl一起升级。

下面是当前在@INC中的目录

$ perl -E'say for @INC'
/home/francesco-salix/perl5/lib/perl5/x86_64-linux-thread-multi
/home/francesco-salix/perl5/lib/perl5
/usr/local/lib64/perl5
/usr/local/share/perl5
/usr/lib64/perl5/vendor_perl
/usr/share/perl5/vendor_perl
/usr/lib64/perl5
/usr/share/perl5
.

我看到一些文件夹看起来是重复的，但我不知道它们是否应该是那样的。但是，在前两条路径中没有Socket.pm (假设cpan在我的用户下运行时添加了这个路径，同时为/usr/local/lib64/perl5/和/usr/lib64/perl5提供了一个Socket.pm文件)。

解决方案是清除旧模块，遵循3 3rensho的评论

sudo rm -rf /usr/local/lib64/perl5/*
sudo rm -rf /usr/local/share/perl5/*

它起作用了!
