我在ubuntu 11.0上安裝了以下版本的rvm。'rvm get head'無法識別的命令行參數：'get'（請參閱：'rvm usage'）Ubuntu 11.10 oneric
$ rvm -v
rvm 1.0.1 by Wayne E. Seguin ([email protected]) [http://rvm.beginrescueend.com/]
但是，在運行rvm get head時，出現以下錯誤。
$ rvm get head && rvm reload
fail: Unrecognized command line argument: 'get' (see: 'rvm usage')
$ rvm update --head

你能幫我弄清楚是什麼問題？以及如何解決它？
