问题描述

RubyGems 是 Ruby 编程语言的包管理器，它提供了一种用于分发 Ruby 程序和库的标准格式(采用称为gem"的自包含格式)，一种旨在轻松管理 gem 安装的工具，以及分发它们的服务器.它类似于 Python 编程语言的 EasyInstall.RubyGems 现在是 Ruby 1.9 版标准库的一部分.

RubyGems is a package manager for the Ruby programming language that provides a standard format for distributing Ruby programs and libraries (in a self-contained format called a "gem"), a tool designed to easily manage the installation of gems, and a server for distributing them. It is analogous to EasyInstall for the Python programming language. RubyGems is now part of the standard library from Ruby version 1.9.

也就是说，GEM_HOME 和 GEM_PATH 有什么区别?

That said, what's the difference between GEM_HOME and GEM_PATH?

推荐答案

GEM_PATH 提供了可以找到 gem 的位置(可能有多个).

GEM_PATH provides the locations (there may be several) where gems can be found.

GEM_HOME 是 gem 的安装位置(默认).

GEM_HOME is where gems will be installed (by default).

(因此 GEM_PATH 应该包含 GEM_HOME).

(Therefore GEM_PATH should include GEM_HOME).
