Question

我的智慧结束了。我在OSX10.6上，我的宝石都搞砸了。我试图使用的宝石之一是Hashie。我在互联网上环顾四周，有几个人似乎遇到了类似的问题，但我的解决方案似乎都不适用于我的情况。谢谢你的期待。

所有我的ruby脚本/宝石都安装在/opt/ruby-enterprise-1.8.7-2010.02中：

Komputor:~$ which ruby gem irb rails
/opt/ruby-enterprise-1.8.7-2010.02/bin/ruby
/opt/ruby-enterprise-1.8.7-2010.02/bin/gem
/opt/ruby-enterprise-1.8.7-2010.02/bin/irb
/opt/ruby-enterprise-1.8.7-2010.02/bin/rails

安装示例gem，hashie（和许多其他）：

Komputor:~ $ gem list -l | wc -l
      67
Komputor:~ $ gem list | grep hashie
hashie (0.4.0)
Komputor:gems $ cd /opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8/gems
Komputor:gems $ ls | grep hashie
drwxr-xr-x  13 root  admin   442 Nov 24 17:13 hashie-0.4.0

然而，当我尝试从irb或脚本访问它们时，它都失败了：

Komputor:~ $ irb
irb(main):001:0> require 'hashie'
LoadError: no such file to load -- hashie
    from (irb):1:in `require'
    from (irb):1
irb(main):002:0>

一些环境变量：宝石环境：

Komputor:gems $ gem env

我很乐意发布任何调试命令的输出。

感谢您的期待！

正如Adam Vandenberg所指出的那样，在加载宝石之前，你需要require "rubygems"

某些框架可能会为您加载此内容，如果您愿意，可以在.irbrc中将其设置为自动加载

Ruby无法找到已安装的gem
