默认系统自带的ruby是ruby 1.8.6,我们就不需要升级了，想升自己升吧

sudo gem install rake-0.8.7.gem

sudo gem install activesupport-2.2.3.gem

sudo gem install activerecord-2.2.3.gem

sudo gem install actionpack-2.2.3.gem

sudo gem install actionmailer-2.2.3.gem

sudo gem install activeresource-2.2.3.gem

sudo gem install rails-2.2.3.gem

sudo gem update --system

下面三个包需要图形化界面安装

MySQLStartupItem.pkg

mysql-5.1.48-osx10.5-x86.pkg

MySQL.prefPane

sudo cp /usr/local/mysql/support-files/my-large.cnf /etc/my.cnf

rails mytest --database=mysql

以上命令则会在你的默认用户文件夹下,建立一个mytest的文件夹

cd mytest

ruby script/server 启动ror
