我刚刚将我的 RoR 开发环境迁移到 Ubuntu。我从 github 上提取了一个正在开发的项目，并尝试安装所有必要的 gem。然而，每当我跑步时bundle or bundle install or bundle install exec我收到以下错误：

An error occured while installing mysql (2.8.1), and Bundler cannot continue.
Make sure that `gem install mysql -v '2.8.1'` succeeds before bundling.
有人处理过这种特殊的疼痛吗？我们将永远感谢您的帮助。
您需要告诉捆绑程序在您的盒子上哪里可以找到 mysql-dev 的东西。通常像下面这样的东西会起作用：
bundle config build.mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config
当然，您需要将上面的路径替换为 mysql_config 的实际路径。如果您没有安装 mysql_config，那么您需要在服务器上安装 mysql-dev 软件包。看起来您可能位于共享服务器上，因此希望开发包已安装。如果没有，您需要提出请求。
