在Ubuntu 12.04.1 LTS上安装ruby 2.0.0-p247

我正试图在我的ubuntu设备上安装ruby 2.0，我不断得到以下信息：

SERVER_USER@SERVER_NAME:/var/www/FOLDER_NAME$ rvm get stable && rvm install ruby-2.0.0

我回来了

ERROR: Unrecognized command line argument: 'requirements' ( see: 'rvm usage' )

我以前没有看到过，结果我的rvm被破坏了，因为我使用了apt get install ruby rvm，而不是直接从rvm.io安装curl，所以重新安装rvm就成功了。
