perl找不到已安装的模块,但CPAN可以,而且我可以找到它们.为什么不能perl？

Question

我在macbook 10.6上使用安装在/ opt/local/bin中的perl 5.16.3的macports

jason-danckss-macbook:eg Jason$ which perl
/opt/local/bin/perl

我正在测试AI附带的demo.pl文件:来自metaCPAN的Categorizer.pm.我安装了AI:通过CPAN随macports perl提供的分类程序:

试图运行它:

原版的:

./demo.pl /users/Jason/Desktop/Dropbox/capstone/capstone/notes/HTML/sock
Can't locate AI/Categorizer.pm in @INC (@INC contains: /sw/lib/perl5/5.10.0/darwin-thread-multi-

BEGIN failed--compilation aborted at ./demo.pl line 21.

略微修改:use lib "/opt/local/lib/perl5/5.16.3";因为当我使用CPAN时,这是模块的写入位置(perl -MCPAN -e shell如果重要,我使用IDK)

jason-danckss-macbook:eg Jason$ ./demo.pl ../HTML/sock

检查它在正确的位置:

jason-danckss-macbook:eg Jason$ find /opt/local/lib/perl5 -name 'Categorizer.pm'
/opt/local/lib/perl5/site_perl/5.16.3/AI/Categorizer.pm

我甚至试图使用诊断.我和perl都不能找到诊断.CPAN找不到它.我猜它是在最近的perl版本中删除的？

好的,所以我的计算机上有fink和macport,以及默认的perl安装.macports版本perl是$ PATH中第一个perl.在它最近出现之后,我对它很满意:5.16.3

我不知道或认为从多个位置读取模块是个坏主意.但是IDK.我不想想我可能需要做什么样的体操来解决这个问题.

有没有人遇到过这个？

我刚看了一下这个AI::Categorizer包,并且包含的demo.pl文件有一个硬编码的shebang,#!/usr/bin/perl所以我相信它正在尝试使用系统perl.

假设你还没有尝试改变这一行(第一行demo.pl)指向/opt/local/bin/perl那时我怀疑这样做会解决你的问题.

您也可以考虑将shebang设置为/usr/bin/env perl应该使用perl路径中的版本.另请参阅perlbrew,这可能是安装非系统版Perl的更好方法.
