我正在使用Centos 6并安装Perl-CPAN和开发工具。我似乎无法安装Test：Harness：：Straps，它会出现以下错误：

Can't locate Module/Build.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at Build.PL line 3.
BEGIN failed--compilation aborted at Build.PL line 3.
Warning: No success on command[/usr/bin/perl Build.PL --installdirs site]

这是我系统：

我是否应该更改mbuild_install_build_command？我使用sudo在此CPU上执行。
我试着从这个网站上按照其他的解决方案，但我仍然得到错误，不能安装其他的TAP，因为模块：：构建错误。是我安装perl-CPAN，而不是yum版本，还是我应该去其他版本而不是5.10.1
