Ruby on rails RubyonRails服务器没有'；开始

我目前正在从事一个项目，该项目要求我接管一个现有的RubyonRails网站并完成它。我对这个很陌生，有一些问题

我甚至不能从终端启动服务器，我怀疑这是一个与版本相关的问题，因为我刚刚将我的计算机配置为使用Ruby on Rails，并且网站开发是在一两年前开始的。如果我自己创建并处理一个项目，一切都会很好。我在OSX Mavericks旗下的MacBook上

以下是一些细节：

要启动服务器，请使用终端进入项目目录并键入：

rails server

此命令提供以下错误消息：

/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)

from script/rails:5:in `<main>'

如果我理解得很好，这会重新安装所有gems，最后我会收到这样一条错误消息：

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

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.

此错误消息建议我应该运行，并确保在绑定之前成功：

gem install mysql2 -v '0.3.11

这就是我得到的：

此时此刻，我被困住了，不知道该怎么办。感谢您的帮助

干杯

我相信有很多与mysql2 gem安装问题相关的问题您安装了mysql吗？简而言之，您需要先使用类似于自制的东西（

brew安装mysql

）来安装mysql二进制文件和库。谢谢大家，这就解决了问题！好几天了，真不敢相信我这么笨，非常感谢
