Linux Perlcpan： 找不到 JSONParse.pm @INC

我在CentOS 7上运行.

我已经通过CPAN安装了JSON::Parse，但收到错误.

Can't locate JSON/Parse.pm in @INC (@INC contains: 
/home/truckassist/modules 
/usr/local/lib64/perl5 
/usr/local/share/perl5 
/usr/lib64/perl5/vendor_perl 
/usr/share/perl5/vendor_perl 
/usr/lib64/perl5 
/usr/share/perl5 .)

当运行cpan JSON::Parse时，我得到以下结果:JSON::Parse is up to date (0.62)

到目前为止，我已经try 了以下几种方法.

perl -e "print qq(@INC)"

输出:

/root/perl5/lib/perl5/5.16.3/x86_64-linux-thread-multi 
/root/perl5/lib/perl5/5.16.3 
/root/perl5/lib/perl5/x86_64-linux-thread-multi 
/root/perl5/lib/perl5 
/usr/local/lib64/perl5 
/usr/local/share/perl5 
/usr/lib64/perl5/vendor_perl 
/usr/share/perl5/vendor_perl 
/usr/lib64/perl5 
/usr/share/perl5

所以:

find /root/perl5 -iname '*json*'个

输出:

/root/perl5/man/man3/JSON::Tokenize.3pm
/root/perl5/man/man3/JSON::Whitespace.3pm

我只能假设它正在查看错误的cpan/perl目录.

有没有人能帮忙或指点方向？
