什么是“需要"路径?默认情况下查找? [英] What are the paths that "require" looks up by default?

问题描述

在Ruby中，有人告诉我这样做的时候

In Ruby, I have been told that when doing

require "some_file"

Ruby将在某些位置查找文件.

Ruby will look for the file in certain places.

我知道它在寻找some_file.rb，但是默认情况下它在哪里寻找?

I know that it looks for some_file.rb, but where does it look for it by default?

推荐答案

这取决于您的平台以及Ruby的编译方式，因此没有"the"答案.您可以通过运行以下内容找出答案:

It depends on your platform, and how Ruby was compiled, so there is no "the" answer to this. You can find out by running:

ruby -e 'puts $:'

但是，通常，您具有标准，站点和供应商的Ruby库路径，包括每个路径下的arch，版本和常规目录.

Generally, though, you have the standard, site, and vendor Ruby library paths, including an arch, version, and general directory under each.
