Question

我刚刚将Slackware64升级到14.1，我发现了Perl 5.18。 Socket.pm现在抱怨它是为另一个Perl版本编译的，它是5.16。这是错误：

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cpan，我甚至无法重新安装Socket.pm.

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

以下是目前@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
.

我看到一些文件夹似乎重复，但我实际上并不知道它们应该是那样的。但是，前两个路径中没有Socket.pm（我假设在我的用户下运行时由cpan添加的路径，而我的Socket.pm文件是/usr/local/lib64/perl5/ /usr/lib64/perl5和{{1}}。

Answer 1

Socket.pm确实是一个核心模块。并且 ~~CPAN.pm模块~~ ExtUtils :: MakeMaker使用它（通过IPC :: Cmd），所以如果Socket.pm被破坏， ~~CPAN.pm~~ Makefile.PL将是也破了。

鉴于它是一个核心模块，并且已经安装了Perl，这告诉我Perl正在尝试从其他一些较旧的路径加载Socket.pm。以下内容将告诉您Perl尝试从以下位置加载模块的位置：

perl -E'say for @INC'

那里有什么可疑之处。它可能会找到为Perl 5.16编译的旧模块的任何地方吗？

Answer 2

解决方案是在3rensho’s comment之后清除旧模块：

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

有效！

升级后无法加载（并重新安装）Socket.pm
