Ruby on rails 安装eventmachine-v'的本机gem时发生编译错误；0.12.10'；

我无法使用

rake bundle\u install安装项目：

$ rake bundle_install
cd nats && bundle install
rake aborted!
Command failed with status (5): [cd nats && bundle install...]

An error occurred while installing eventmachine (0.12.10), and Bundler cannot continue.
Make sure that `gem install eventmachine -v '0.12.10'` succeeds before bundling.

然后，当我尝试所需版本的
eventmachine
时，我得到了以下输出：

$  sudo gem install eventmachine -v '0.12.10'
ERROR:  Error installing eventmachine:

我已完成以下设置：

$ rake --version
rake, version 0.9.2.2
$ ruby -v
ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]

如何解决此问题？
据我所知，此版本似乎存在问题，我发现解决此问题的唯一方法是这样。我的建议是查看Gemfile.lock，看看哪个gem需要这个版本，考虑一下您是否真的需要它，或者检查这个gem是否是更新的，因为它是eventmachine的一个非常旧的版本
 为什么要使用这样一个旧版本的gem？原因是在
rake bundle\u install
的输出结束时，它要求在尝试设置项目之前尝试
gem install eventmachine-v'0.12.10'
。我试图通过以下方法解决这个问题，这是一个ruby版本的问题。我最终安装了
ruby1.9.3p551
和
rvm
。
