当安装了两个版本的模块时，Perl会做什么? [英] What does Perl do when two versions of a module are installed?

问题描述

我在正在使用的远程机器上没有root用户访问权限，因此我正在使用cpanm和local :: lib的组合，如

I don't have root access on a remote box I'm working with, so I'm using a combination of cpanm and local::lib as described here to install CPAN modules to my local directory on the box. Using cpanm, I assume cpanm Module::To::Update would install the newest version of the module in my local library.

显然，我不需要root访问权限即可升级CPAN模块，就像我刚刚尝试过的那样，升级过程非常顺利.但是，我仍然很好奇Perl将使用哪个模块版本:本地版本还是默认的CPAN版本?还是只使用较新的一个?

Apparently, I don't need root access to upgrade my modules with CPAN, as I just tried it, and the upgrade went swimmingly. However, I'm still curious which version of the module Perl will use: the local version, or the default CPAN version? Or will it just use whichever is newer?

如果这在perldoc或Stack Overflow中存在，我也将不胜感激.我尝试同时搜索两者，但是找不到它=/

If this exists in perldoc or Stack Overflow, I'd appreciate that as well. I tried searching both, but I wasn't able to find it =/

推荐答案

它使用通过 @INC .

It uses the first one it finds when searching though @INC in order.
