Ruby on rails 尝试运行gem命令时运行RubyGems插件时出错

我在尝试运行

gem

命令时遇到此错误。有人知道这是什么原因吗？这导致我无法运行

railsgmigration

命令（我得到一个类似的错误），我可能会想象更多

更新：我还尝试了

rake

命令，它抛出了相同的错误。

我发现了一个与 ，看起来可能是（1）Ruby安装问题，或者（2）RubyGem问题。如果它是一个Ruby问题，您需要使用RVM（Ruby版本管理器）卸载并重新安装Ruby，这似乎对一些人有效。如果是（2）RubyGem问题（很可能是），则必须删除“/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

建议的用户之一（您可以从链接中找到）： *当我使用“gem-v”时，响应将给出错误“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_安装程序（加载错误） 所以我编辑了“rubygems_plugins.rb”，修改了rubygems_bundler的require路径，修改后的路径是“/rubygems_bundler/{file_name}”，问题解决了。“*

我希望这些说明+链接能帮助你解决这个问题。去年夏天我确实阅读了Michael Hartl的同一本教程。我想我遇到了类似的问题。我想我可能删除了一个文件夹来解决这个问题，也许还重新安装了一些东西（但我不是100%，因为已经有一段时间了）.

试着打电话

$gem更新--系统
