问题

比如现在需要在 Perl 中使用 ImageMagick, 在 .pl 文件中通常要写

use Image::Magick;

也就是启用 Image::Magick 模块. 如果 Perl 是默认安装的, 则不会预先安装此模块. 在执行 .pl 文件时, 会提示下面的信息

Can't locate Image/Magick.pm in @INC (you may need to install the Image::Magick module) (@INC contains: C:/Strawberry/perl/site/lib C:/Strawberry/perl/vendor/lib C:/Strawberry/perl/lib) at test.pl line 6.
BEGIN failed--compilation aborted at test.pl line 6.

如果安装的是 strawberry Perl, 则已经安装了 cpanm. 在 Windows 下可以通过 where cpanm 查看其是否能直接调用.

然后通过 

cpanm Module::Name

直接安装需要的模块. 模块可以在 CPAN 网上查找.

例如: 在命令符窗口下键入 cpanm Image::Magick  就可以安装 Image::Magick 模块.

cpanm Image::Magick

键入 perl -MCPAN -e shell 可进入 CPAN 的 shell 模式

perl -MCPAN -e shell
