我的 Perl 和 cpan 安装已损坏。 Perl 版本如下所示，该命令执行并运行良好。
>perl -v
This is perl 5, version 16, subversion 3 (v5.16.3) built for x86_64-linux-thread-multi
(with 34 registered patches, see perl -V for more detail)
但是，当我尝试运行 cpan 以安装 perl 模块时，cpan 返回此错误，
> cpan
Fcntl object version 1.11 does not match $Fcntl::VERSION 1.13 at /usr/lib64/perl5/DynaLoader.pm line 213.
Compilation failed in require at /usr/share/perl5/CPAN/FTP.pm line 6.

BEGIN failed--compilation aborted at /usr/bin/cpan line 8.
当我再次运行 shell 版本的 CPAN 时，我得到了同样的错误。 Dynaloader.pm 版本似乎与以前安装的版本有一些冲突
version or something.
> sudo perl -MCPAN -e shell

- 如何解决动态加载冲突和错误？
- 为什么 perl -V 返回编译失败错误？
- 这些错误是否意味着 perl 安装已损坏？
谢谢。
