无法在 Ubuntu 服务器上安装 Mysql gem

Question

我在 gem 文件中添加了 mysql gem，但是当我运行 bundle install 时，它显示以下错误。

An error occurred while installing mysql (2.9.1), and Bundler cannot continue. Make sure that `gem install mysql -v '2.9.1'` succeeds before bundling.

我正在我的 Ubuntu 机器上安装这个 gem。我使用的是 rails 版本 4.2.0 和 ruby​​ 2.1.7。我在下面解释 mu gemfile。
