Why cant I download modules?

Hello guys am having a problem with downloading modules. Anytime i try to download a module , i get some weird messages. Its possible am doing something wrong because I haven't done it before, so its 开发者_运维问答my first module.

The error message i get after running

cpan WWW::Mechanize 

is

cpan WWW::MechanizeError while requiring CPAN::MyConfig:Can't find string terminator "]" anywhere before EOF at /Users/fayimora/.cpan/CPAN/MyConfig.pm line 5.
Compilation failed in require at /System/Library/Perl/5.10.0/CPAN/HandleConfig.pm line 478.}

Please how do i fix this so I can start downloading and using modules from CPAN. Thanks in advance
