Can't locate File/Copy/Recursive.pm in @INC (@INC contains:

今天运行perl脚本的时候，发现一个找不到“Recursive.pm”的错误：

Can't locate File/Copy/Recursive.pm in @INC (@INC contains: /opt/local/lib/perl5/site_perl/5.12.4/darwin-thread-multi-2level

BEGIN failed--compilation aborted at xxxx.pl line 6.

解决的方法是安装缺少的Recursive.pm，敲入下面的命令：

android:antt lee$ perl -MCPAN -e install "install File::Copy::Recursive"

或者

android:antt lee$ sudo cpan install File::Copy::Recursive
