我通过cpan安装了一个perl模块。但是我该如何使用它呢？

Question

在经历了许多问题之后，我设法让cpan在cygwin中工作。

我做到了：cpan[2]> i Log::Log4perl，而且它似乎起作用了。例如，它下载了一些东西：

cpan[2]> i Log::Log4perl  
Fetching with LWP:

..............  
  New CPAN.pm version (v2.00) available.  
  [Currently running version is v1.960001]  
  You might want to try  
    install CPAN  
    reload cpan  
  to both upgrade CPAN.pm and run the new version without leaving  
  the current session.

Module id = Log::Log4perl

    CPAN_VERSION 1.41  
    CPAN_FILE    M/MS/MSCHILLI/Log-Log4perl-1.41.tar.gz  
    DSLIP_STATUS ampOp (alpha,mailing-list,perl,object-oriented,Standard-Perl)  
    INST_FILE    (not installed)  

因此，现在我有了以下简单的脚本：

#!/usr/bin/perl  

use strict;  
use warnings;  

use Log::Log4perl qw(:easy);  

当我尝试运行它时，我得到：

Can't locate Log/Log4perl.pm in @INC

我在~/.cpan下搜索Log4perl.pm，但是我找不到它。为什么？不是cpan安装的吗？我还需要做些别的事情吗？

cpan i提供有关包的信息。

使用cpan install ...安装程序包。
