Terminal Can'；t在终端中运行Grunt命令-在SASS处卡住

我得到一个奇怪的错误：

/Library/Ruby/Site/1.8/rubygems/ext/builder.rb:12: uninitialized constant Gem::UserInteraction (NameError)

有人有什么建议吗？我认为这可能是一个路径问题，只是不知道如何重置它

以下是错误消息：

这看起来像是更新中的一些问题

您可以尝试更新：

gem update --system
gem update sass

---

我不完全确定原因是什么，但我认为最近的一次gem更新为我打破了它（因为一些rubygems版本附带了问题：）

---

对我来说，解决这个问题的方法是手动从下载和安装rubygems。试一试，在我们等待有人解释根本原因时，可能也会解决您的问题。

这些命令不起作用-只是收到一条错误消息。不知道该怎么办？这里也是一样，在尝试任何gem命令（gem list/update等）时，我得到了一个类似的错误：/Library/Ruby/Site/1.8/rubygems/config_file.rb:40:uninitialized constant gem:：UserInteraction（namererror）
