Make sure that `gem install eventmachine -v '1.0.3'` succeeds before bundling.

我正在尝试安装缺少的 gems 以便我可以使用 drush omega-guard

There was a problem with your setup:                                 [error]

Bundler can't satisfy your Gemfile's dependencies.
Install missing gems with `bundle install`.

但是我得到了 eventmachine 的错误，我该如何解决这个问题？我尝试更改 ruby​​ 的版本以查看它是否有效，但我遇到了一些其他错误。

显然您没有 C++ 编译器。如果您使用的是 Ubuntu，请尝试 sudo apt-get install g++。
