ruby-on-rails – 使用Bundler GEM不会安装Ruby Gem(EventMachine)

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.

解决方法

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“他们开始使用Ruby 2.2的那一刻,他们弃用了一堆库并将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. “.
