加载rubygems时出错 [英] Error loading rubygems

问题描述

在一个需要加载rubygems（从config / boot.rb文件）中进行的操作（rspec相关）期间，我收到以下错误消息：

During an operation (rspec related) that required loading rubygems (from config/boot.rb file) I got the following error message:

~/config/boot.rb:1:in `require': no such file to load -- rubygems (LoadError)
~/config/boot.rb:1
    from ~/config/application.rb:1:in `require'
    from ~/config/application.rb:1
    from ~/config/environment.rb:2:in `require'
    from ~/config/environment.rb:2
    from ~/spec/spec_helper.rb:3:in `require'
    from ~/spec/spec_helper.rb:3
    from ~/spec/models/user_spec.rb:1:in `require'
    from ~/spec/models/user_spec.rb:1
    from /usr/lib/ruby/1.8/spec/runner/example_group_runner.rb:15:in `load'
    from /usr/lib/ruby/1.8/spec/runner/example_group_runner.rb:15:in `load_files'
    from /usr/lib/ruby/1.8/spec/runner/example_group_runner.rb:14:in `each'
    from /usr/lib/ruby/1.8/spec/runner/example_group_runner.rb:14:in `load_files'
    from /usr/lib/ruby/1.8/spec/runner/options.rb:132:in `run_examples'
    from /usr/lib/ruby/1.8/spec/runner/command_line.rb:9:in `run'
    from /usr/bin/spec:3

我寻找这个错误所以，发现了以下主题：
找不到ruby gem它被安装了和
没有这样的文件加载 - - ruby​​gems（LoadError）

I looked for this error on SO and found the following topics: ruby gem not found although it is installed and no such file to load -- rubygems (LoadError)

然而他们都提到这个问题可能来自机器上多个版本的ruby的存在。事实上，情况就是这样，所以我决定使用RVM运行全新的ruby和rails安装。但是我仍然遇到同样的问题！

However they both mentionned that the problem could come from the existance of multiple versions of ruby on the machine. Actually that was the case, so I decided to run a fresh installation of ruby and rails using RVM. But I still have the same problem!

其他信息：

Additional information:

which ruby
/usr/local/rvm/rubies/ruby-1.9.2-p136/bin/ruby

which rails
/usr/local/rvm/gems/ruby-1.9.2-p136/bin/rails

which gem
/usr/local/rvm/rubies/ruby-1.9.2-p136/bin/gem

gem --version
1.5.0

ls /usr/lib/ruby
1.8  1.9.1  gems

任何想法？

推荐答案

所以我显然解决了我的问题通过使用命令 rspec 而不是 spec 。如果有人能够解释幕后实际发生的事情，那就太好了！

So I apparently solved my problem by using the command rspec instead of spec. If someone can explain what is actually going on behind the scene, it would be great!
