问题描述

更新:

eventmachine gem 已安装并在我的 gemfile 中:

the eventmachine gem is installed and in my gemfile:

请帮忙！尝试使用以下内容创建数据库:

推荐答案

有人在评论中回答...见下文.

Someone kind of answered in comments...see below.

基本上，虽然我有不同版本的 Ruby，但由于某些 gem 只安装在某些版本的 ruby​​ 上，这让我感到困惑.

Basically though I had seperate versions of Ruby, which was getting confusing because some gems were only installed on certain versions of ruby.

修复完全卸载 ruby​​ 和 rails，然后重新安装.修好了！

这有帮助:

此评论在另一个线程中似乎对您的问题很有希望.你能确保你的 Gemfile 中有gem eventmachine"或类似的东西，并且可以成功捆绑吗?– 斯科特赫尔姆 1 月 6 日 6:24

This comment in another thread seems promising for your issue. Can you ensure that you have "gem eventmachine" or similar in your Gemfile, and can successfully bundle? – Scott Helm Jan 6 at 6:24
