Question

尝试运行gem命令时出现此错误。有谁知道是什么原因造成的？这导致我无法运行rails g migration命令（我得到类似的错误），我想可能还有更多。

更新：我还尝试了rake命令，它会抛出相同的错误。

我找到了与same problem相关的较旧链接，它似乎可能是（1）Ruby安装问题，或（2）RubyGem问题。如果它是一个Ruby问题，你需要使用RVM（Ruby版本管理器）卸载并重新安装Ruby，它似乎对某些人有效。如果是（2）RubyGem问题（它可能是），你要么必须删除'/Users/storwell/.rvm/gems/ruby-2.0.0-p247@global/gems/executable-hooks-1.2.2/ '文件夹或更改rubygems_plugin.rb文件中的内容。

其中一位用户建议（您可以从链接中找到）： *“当我使用”gem -v“时，响应会给我错误”加载RubyGems插件时出错“/Users/mercury/.rvm/gems/ruby-1.9.3-p194@global/gems/rubygems-bundler- 0.2.8 / lib / rubygems_plugin.rb“：无法加载此类文件 - rubygems_bundler / rubygems_bundler_installer（LoadError）所以我编辑“rubygems_plugins.rb”，然后我更改了rubygems_bundler的require路径，修改后的路径为“./rubygems_bundler/ {file_name}”，问题解决了。“*

我希望这些说明+链接可以帮助您解决问题。去年夏天，我确实通过了Michael Hartl的同一本教程。我想我遇到过类似的问题。我想我可能已经删除了一个文件夹以解决问题，也许还重新安装了一些东西（但我不是100％，因为它已经有一段时间了）。
