Ruby on rails Can'；在意外运行$gem update--system之后，请不要运行rails服务器

我运行了

gem更新--system

，认为它可以解决我遇到的问题，现在我无法运行

rails服务器。它不会加载，取而代之的是，我不断得到以下信息。有人能告诉我在运行更新之前如何撤消此操作并恢复到

我已经运行了git签出，但问题仍然存在

最新版本的Rubygems似乎有缺陷

您只需使用以下命令恢复到旧版本，一切正常：

gem update --system 1.8.24

我今天也有同样的问题。将bundler更新至最新版本修复了此问题：

gem update bundler

如果您正在运行rbenv

rbenv rehash

您需要升级bundler吗？在尝试引导RubyMine调试ruby脚本时，我看到了类似的错误（错误类似于：stub\u source\u index170:未初始化的常量Gem:：SourceIndex（NameError）），这对我来说很有效。只是gem update bundler修复了它。我认为根据另一个答案更新bundler比降级rubygems更好：）我同意，这就是为什么我对另一个答案投了赞成票！我也应该编辑我的吗？@DanielRistic，没关系。我第一次试过布鲁诺，但在我的情况下没有成功。你的工作很有魅力。对答案和问题进行投票表决。
