我真的不知道如何解决这个问题，我已经将 eventmachine gem添加到Gemfile中，但是它没有帮忙...

I don't really know how to fix this, I've added the eventmachine gem into the Gemfile, but it didn't help...

您能帮我解决一下吗？

谢谢

推荐答案

在我的情况下，此问题已解决：

In my case this fixed it:

• $ gem uninstall eventmachine


• 在提示符下告诉它卸载所有版本（它告诉您有关依赖项的信息）


• $ bundle install

我正在阅读 https://github.com/eventmachine/eventmachine/issues/333 。 eventmachine出现问题，因此确保获得最新版本似乎是个好主意。

I was reading through this https://github.com/eventmachine/eventmachine/issues/333. There were problems with eventmachine, so making sure I got the newest version seemed a good idea.
