Ruby Gem（EventMachine）不会使用Bundler GEM安装

Question

所以我正在尝试安装GitLab，他们让我使用名为“bundler”的gem，它基本上安装了运行应用程序所需的GEM。 无论如何，在运行捆绑器后使用：

sudo -u git -H bundle install --deployment --without development test mysql aws

这将完美安装一吨宝石然后大约2分钟进入安装我将在终端中收到以下错误。

Ruby版本：来自SVN的最新版本（我已经检查过并且很好）

操作系统：Ubuntu 14.04 LTS（Trusty）

An error occurred while installing eventmachine (1.0.3), and Bundler cannot continue.
Make sure that `gem install eventmachine -v '1.0.3'` succeeds before bundling.

这可能只是ruby 2.2中的一个问题所以你可能会尝试使用2.1作为“当他们开始使用Ruby 2.2时，他们不赞成使用一堆库并将readline升级到更新的版本。当他们这样做时，它打破了比Ruby 2.2更少的东西。 “。
