RVM红宝石如何找到宝石？ [英] How do RVM rubies find gems?

问题描述

我在Mac OS X（10.9.2）的RVM下使用了Ruby 1.8.6。我将所有东西安装为本地用户（不是root），然后使用以下命令安装gem：

  gem install gli -v 1.6 
  

当我用 require（'gli'）


  in'require'：no file to load  -  gli（LoadError）
  

即使 gem list 显示 gli（1.6.0）。





我不确切知道RVM如何做它的gemsets，但是没有 $ LOAD_PATH 。

<$ c $>中的任何一个目录中的$ c> gli.rb p> RVM如何与 $ LOAD_PATH 进行交互以在gemset中找到必要的gem？

解决方案

尝试在源文件的顶部添加 require'rubygems'>。在默认情况下，不需要1.8版的rubygems。

$ c> GEM_HOME 指示安装宝石的位置。要找出你的情况是什么：

  $ echo $ GEM_HOME 
  

这应该显示与RVM相关的路径，因为RVM会更改此环境变量以使 $ gem install 命令在其目录中安装宝石。

I'm using Ruby 1.8.6 under RVM on Mac OS X (10.9.2). I installed everything as a local user (not root), and then installed a gem using:

gem install gli -v 1.6

When I run a ruby with require('gli'), I get the error:

in `require': no such file to load -- gli (LoadError)

even though gem list shows gli (1.6.0).

I don't know exactly how RVM does its gemsets, but there is no gli.rb file in any of the directories in the $LOAD_PATH.

How does RVM interact with the $LOAD_PATH to find the necessary gems in the gemset?

解决方案

Try adding a require 'rubygems' at the top of your source file. In 1.8 rubygems aren't required by default.

Thus said, regarding gem paths:

GEM_HOME indicates where gems are installed. To find out what it is for your case do:

$ echo $GEM_HOME

This should display an RVM-related path, since RVM changes this environment variable in order to make the $ gem install command install gems in its directories.
