rubygems – Ruby无法找到已安装的宝石

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.

我的所有ruby脚本/ gem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

并安装了示例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.

谢谢你的期待！

解决方法

正如Adam Vandenberg指出的那样,在加载宝石之前,你需要“rubygems”

有些框架可能会为您加载,如果您愿意,可以将其设置为.irbrc中的自动加载
