Perl 模块的自动安装

好吃的terry

我写的脚本，上传到github上，但脚本中用到了cpan中的一些模块，如：

1. use LWP::Simple;
   
2. use Data::Dumper;
   
3. use XML::Simple;
   

复制代码

用什么方法可以使别的开发者自动安装脚本中依赖的Perl模块？
谢谢～

    把你自己的脚本也做成一个模块，然后在Makefile.PL里面定义依赖关系,http://www.perlmonks.org/?node_id=431702#makefile_pl
Makefile.PL
There is a file called Makefile.PL. By looking at it, you might think that you actually don't need to do anything to it; and that might be true, most of the times.

If you used h2xs, you should check its parameters. Otherwise, you should be fine.

However, there is one situation when you absolutely should update Makefile.PL: when you use other modules. That is, when your module has dependencies.

Just go there and add something like this:


然后用cpanm安装

在代码的最开始这么写

BEGIN {
    eval {
        require LWP::Simple;
    };
    if ($@ =~ /^Can't locate/) {
        print "install module LWP::Simple";
        # 调用 cpan 命令安装模块
    }
}

# 正文

use LWP::Simple;

    感谢回答，感觉写一个类似的运行时依赖模块自动安装比较有意思。
