【问题描述】：

在需要加载 rubygems（来自 config/boot.rb 文件）的操作（rspec 相关）期间，我收到以下错误消息：

~/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

我在 SO 上查找了这个错误，发现了以下主题： ruby gem not found although it is installed 和 no such file to load -- rubygems (LoadError)

但是他们都提到问题可能来自机器上存在多个版本的 ruby。实际上就是这样，所以我决定使用 RVM 重新安装 ruby 和 rails。但是我还是有同样的问题！

附加信息：

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

有什么想法吗？

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

【讨论】：

您尝试使用哪个版本的 rspec？ spec 已被弃用，因此您可能会尝试使用旧版本的 rspec。
好 :) 如果您安装了任何旧的 rspec gem，我会尝试删除。
