Rails 4.2和gem配置坏了

Question

我的OS X ruby​​开发环境坏了，我不知道为什么。 我不喜欢宝石路径是错误的，但我不知道如何解决它。

/Users/muqaddar/.rvm/rubies/ruby-2.0.0-p598/lib/ruby/site_ruby/2.0.0/rubygems/dependency.rb:315:in `to_specs': Could not find 'rails' (>= 0) among 14 total gem(s) (Gem::LoadError)
Checked in 'GEM_PATH=/Users/muqaddar/.rvm/gems/ruby-2.0.0-p598:/Users/muqaddar/.rvm/gems/ruby-2.0.0-p598@global', execute `gem env` for more information
    from /Users/muqaddar/.rvm/rubies/ruby-2.0.0-p598/lib/ruby/site_ruby/2.0.0/rubygems/dependency.rb:324:in `to_spec'
    from /Users/muqaddar/.rvm/rubies/ruby-2.0.0-p598/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_gem.rb:64:in `gem'
    from /usr/bin/rails:22:in `<main>'

这是我的gem env配置：

RubyGems Environment:
  - RUBYGEMS VERSION: 2.4.6

     - /Users/muqaddar/.rvm/bin

我尝试了很多东西，阅读了很多线程。 - 重新安装rvm - 删除.vendor / bundle - bundle install ...等

我认为宝石没有安装在正确的目录中。 如何根据我的rvm配置更改它？

如果您使用的是mac， 请尝试按以下步骤操作： http ： //www.installrails.com/

请注意，在安装新gem时，首先必须将其添加到编辑器中的Gemfile中。 例如：gem'bootstrap-sass'，'〜> 3.3.3'执行此操作后，使用终端导航到您的文件夹并输入：“bundle install”。 这将安装您添加的宝石。
