然后开始写了个文件操作的脚本,里面有个Path::Class模块。

use Path::Class; 
C:PerlLearn>perl FindFile.pl 
Can't locate Path/Class.pm in @INC (@INC contains: C:/Perl/site/lib/MSWin32-x86- 
multi-thread C:/Perl/site/lib C:/Perl/lib .) at FindFile.pl line 4. 
BEGIN failed--compilation aborted at FindFile.pl line 4. 

看提示,像没有安装该包,安装了下该包,结果果然没报这种错误:

C:PerlLearn>cpanm Path::Class 
Set up gcc environment - 3.4.5 (mingw-vista special r3) 
--> Working on Path::Class
