ruby-on-rails - Ruby on Rails 控制台在加载时挂起

Question

无论出于何种原因，Ruby on Rails 控制台拒绝启动；它只是挂起。我没有对我的代码做任何更改，其他使用相同版本的 Ruby 和 Ruby on Rails 的项目没有问题。当我最终 Ctrl + C 时，我得到了这个指向 Spring 的堆栈跟踪。

我无法解释为什么这种情况时时刻刻都在发生，而它运行良好。我已经通过 RVM 清除了所有的 gem，并通过 bundle 命令重新安装了所有的 gem，但仍然没有成功。任何想法将不胜感激。

据我所知，Ruby on Rails 服务器也没有问题。该问题与项目相关，但没有更改任何代码，只有 Ruby on Rails 控制台有问题。

ruby 2.1.2
rails 4.1.4

重新启动 Spring 应该可以修复挂起的命令:

$ bin/spring stop

在删除并重新创建新的 Ruby on Rails 应用程序后，我遇到了挂起的命令(rake、bin/rails 等)。谷歌没有那么有用。我希望是这样。

当您重新运行命令时，Spring 将自动启动。
