我正处于Ruby on Rails编码过程中，在最近一个小时内运行了几个rails生成方法，突然一个新的生成命令抛出错误消息。当我尝试通过rake运行我的测试时出现类似的错误。然后在命令行中输入“rails”。然后对于“宝石”命令相同的错误。Rails/Gem命令突然抛出错误
所以我想，不知何故，我打破了我的“rubygems”宝石文件？这是令人担忧的，因为我在卢西丁编码，并且坦白地说，远不及它！
任何人都可以帮助解释可能发生了什么，以及最好的解决方案可能是什么？现在，我会尝试重新安装Ruby，但这是一个昂贵的解决方法，我想避免多次执行。
错误堆栈跟踪如下所示：

我的宝石文件（以上项目）是：
source 'http://rubygems.org'
gem 'rails', '3.0.7'
gem 'sqlite3'
gem "jquery-rails"
虽然在所有命令行实例出现错误。
[编辑]在这个阶段，我已经完全重新安装红宝石和铁轨，问题已经消失。尽管如此，我仍然保留旧的安装目录，以防万一我们能够解决这个问题的底部，或者万一它再次发生！
[第二编辑]新的安装，机器重启后，创业板再次启动失败，并且是的RubyMine说，它不能找到任何宝石（甚至RubyGems的）：

也许是的RubyMine拧安装？还是Windows 7？我的核心开发语言永远不会出现问题 - 非常令人沮丧！
轨和宝石命令在其他项目环境正常工作？你能否在另一个目录中创建新的rails项目？将您的Gemfile内容添加到问题文本。 – crsde 2011-05-02 06:58:33
rails和gem命令在所有环境中都失败（通过Rubymine和命令行调用）。因为所有的命令都会抛出一个如上所述的错误，所以不能做任何与rails相关的操作。 – Phantomwhale 2011-05-02 07:53:53
