【Rails】用gem安装MySQL组件出现Failed to build gem native extension错误的解决办法

下午把一个rails程序的production模式采用MySQL数据库时，执行bundle install 提示我先确认 gem install mysql -v '...' 

我去执行后者，出现错误如下：

Error installing mysql2: ERROR: Failed to build gem native extension

后来上stackoverflow解决，方法如下：

On Ubuntu/Debian and other distributions using aptitude:sudo apt-get install libmysql-ruby libmysqlclient-devOn Red Hat/CentOS and other distributions using yum:sudo yum install mysql-develOn Mac OS X with Homebrew:brew install mysql
