Perl CPAN安装报错CPAN::Modulelist的解决办法

今天安装DBD::mysql，以前都是顺顺利利的，一点事都没有，今天莫名出现：
Warning: Your /root/.cpan/sources/modules/02packages.details.txt.gz does not contain a Last-Updated header.
Please check the validity of the index file by comparing it to more
than one CPAN mirror. I'll continue but problems seem likely to
happen.
Going to read /root/.cpan/sources/modules/03modlist.data.gz
Can't locate object method "data" via package "CPAN::Modulelist" (perhaps you forgot to load "CPAN::Modulelist"?) at (eval 20) line 1.

也不知道哪出问题了
直接在perl -MCPAN -e shell下执行install Bundle::DBD::mysql
出错
强制执行force install Bundle::DBD::mysql
一样的错误
下载tar包安装，出错，rpm包安装也出错，真郁闷了

看错误信息，难道是CPAN::Modulelist这个模块没装？下载这个模块，同样安装出错。。。

郁闷了。。。
对比发现~/.cpan目录下少了很多文件
难道是这个的问题？
删除掉，然后直接在perl -MCPAN -e shell中执行reload index
装了差不多一个小时，cpan在线安装就这不好，超级慢，检测的东西超多，所以我还是喜欢下载包进行安装，不过千万不要执行make test步骤，要不慢死
然后执行install Bundle::CPAN
最后执行reload CPAN即可正常通过命令行install MODULES

再安装DBD::mysql一切顺利
进入cpan检查安装情况：
cpan[1]> m DBD::mysql
