无法在Mac Os下通过Gem安装Mysql的问题

在Mac Os下通过Gem安装Mysql时，老是报错：

Java代码

Building native extensions. This could take a while...

ERROR: Error installing mysql:

ERROR: Failed to build gem native extension.

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb

貌似是缺少了某些文件导致的，于是看了看/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb发现extconf.rb好像需要Mysql的PATH，于是执行：

Java代码

export PATH=$PATH:/usr/local/mysql/bin

sudo gem install mysql -v '2.8.1'

问题解决：
