As of the latest version of lion (and having installed sass/compass/haml), if you type "rails" in the terminal and you dont have it, it will tell you to just do a sudo install right there. Hope its as easy for you as it was for me.
对于最新版本的 Lion（并且已经安装了 sass/compass/haml），如果您在终端中输入“rails”而您没有它，它会告诉您只需在那里进行 sudo 安装。希望它对你和我一样容易。
