perl：无法找到模块，但它在@INC路径中？

Question

在这种特殊情况下，我试图访问IPC :: Open3：

bash-4.2# perl RunScript hier_clustering1.py
Can't locate IPC/open3.pm in @INC (you may need to install the IPC::open3 module) (@INC contains: /root/perl5/perlbrew/perls/perl-5.20.0/lib/site_perl/5.20.0/x86_64-linux /root/perl5/perlbrew/perls/perl-5.20.0/lib/site_perl/5.20.0 /root/perl5/perlbrew/perls/perl-5.20.0/lib/5.20.0/x86_64-linux /root/perl5/perlbrew/perls/perl-5.20.0/lib/5.20.0 .) at RunScript line 4.
BEGIN failed--compilation aborted at RunScript line 4.
bash-4.2# cd /root/perl5/perlbrew/perls/perl-5.20.0/lib/5.20.0
bash-4.2# cd IPC
bash-4.2# ls
Cmd.pm  Open2.pm  Open3.pm

正如您所见，IPC :: Open3已明确安装并且在路径中。

这是在perlbrew shell中运行perlbrew安装的perl：

bash-4.2# which perl
/root/perl5/perlbrew/perls/perl-5.20.0/bin/perl

这是怎么回事？

检查您的大小写。 open3和Open3不同。
