编辑:

我找到了另一个用于安装MySQL的SO链接。在尝试使用自制软件之前,请先尝试这样做 Unable to install MySQL on Mac OS X

自制:

使用自制软件是安装MySQL的另一种解决方案 实际上我几乎用其他所有东西都使用自制软件。

这是与文档的安装链接。
https://github.com/mxcl/homebrew/wiki/installation

基本命令/自述。
http://mxcl.github.com/homebrew/

安装后,您可以

brew install mysql

以下是一些可以指导您的Google搜索结果(搜索结果为brew install mysql) 如果您有root密码问题,则可以使用SO链接 http://solutions.treypiepmeier.com/2010/02/28/installing-mysql-on-snow-leopard-using-homebrew/
brew install mysql on mac os

安装mysql之前安装以下gem。这是为了ubuntu ..

sudo apt-get install mysql-server mysql-client
sudo apt-get install libmysql-ruby libmysqlclient-dev
