我刚刚将我的RoR开发环境迁移到了Ubuntu。 我从github上下了一个项目，试图安装所有必要的gem。 但是，每当我运行bundle或bundle install或bundle install exec我得到以下错误：

有没有人处理过这种特殊的痛苦？ 您的帮助是永远赞赏。
你需要告诉打包者在哪里找到你的盒子上的mysql-dev的东西。 通常像下面这样的工作：
bundle config build.mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config
当然，你需要用你实际的路径替换上面的路径到mysql_config。 如果你没有安装mysql_config，那么你将需要在你的服务器上安装mysql-dev软件包。 看起来你可能在共享服务器上，所以希望已经安装了开发包。 如果没有，你需要请求它。
您在Ubuntu 14.04（Trusty）上缺少的库是： libmysqlclient-dev 。 下面的行为我做了诡计：
sudo apt-get install libmysqlclient-dev
