CPAN安装perl模块报错( CPAN::Modulelist )解决办法

在使用CPAN安装PERL模块的时候，报如下错误的解决办法：

解决办法如下：

[root@localhost CPAN]# perl -MCPAN -e shell

cpan[1]> reload index    #执行此步就可以了。

因为我是安装REDIS的sharding 布局，需要安装PERL的EV和CRC32 模块。其中在安装EV的时候，是正常的。

cpan[2]> install EV

但是在安装 CRC32的时候，有如下提示：

cpan[1]> install CRC32

Going to read '/root/.cpan/Metadata'

Warning: Cannot install CRC32, don't know what it is.

Try the command

    i /CRC32/

to find objects with matching identifiers.

按提示我们执行：

cpan[2]> i /CRC32/
Distribution FAYS/Digest-Crc32-0.01.tar.gz
Distribution SOENKE/String-CRC32-1.4.tar.gz
Module < Digest::Crc32 (FAYS/Digest-Crc32-0.01.tar.gz)
Module < String::CRC32 (SOENKE/String-CRC32-1.4.tar.gz)
4 items found

接下分别安装： Digest::Crc32和String::CRC32我就可以了。

cpan[3]> install Digest::Crc32

cpan[4]> install String::CRC32
