我目前正在开展一个项目，要求我接管现有的Ruby on Rails网站并完成它。我对此非常陌生，并且遇到了一些问题。
我甚至无法从终端启动服务器，我怀疑这是与版本相关的问题，因为我只是将我的计算机配置为使用Ruby on Rails，并且网站开发开始了一年或两个月前。如果我自己创建并处理项目，一切正常。我是OSX Mavericks的MacBook上的。
以下是一些细节：
要启动服务器，我使用终端进入项目目录并输入：
rails server
此命令给出了以下错误消息：
/Users/Davydov/.rvm/rubies/ruby-2.1.0/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- bundler/setup (LoadError)

我当然在网上浏览这个问题很长一段时间，有人告诉我这样做：
bundle install
如果我理解这很重新安装了所有的宝石，最后我收到一条错误消息：

An error occurred while installing mysql2 (0.3.11), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.11'` succeeds before bundling.
此错误消息表明我应该运行，并确保在捆绑之前成功：
gem install mysql2 -v '0.3.11
这就是我得到的：

此刻我被困住了，不知道该怎么做。所有的帮助都表示赞赏。
