Perl CPAN::Modulelist的解决办法

今天用CPAN安装Term::ReadLine,报了个这样的错误

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 31) line 1.

google结果有人是这样解决的

rm -rf ~/.cpan
删除后在perl -MCPAN -e shell中执行reload index
然后执行install Bundle::CPAN
最后执行reload CPAN即可正常通过命令行install MODULES

我按照这个做,结果reload index执行都报错,继续google,发现应该是Config.pm的问题,重新配置

cpan> o conf urllist unshift http://www.perl.com/CPAN/
cpan> o conf commit

然后再执行上面的reload index之后的步骤就OK了。
