Ruby on rails 尝试使用rvm卸载2.2.1卸载ruby 2.2.1时，权限被拒绝

我使用的是OS X约塞米蒂版本10.10.4，我对ruby和rails还不熟悉。正在尝试为我正在学习的类构建测试应用程序，但无法卸载ruby重新开始

检查权限

ls-l/Users/thomascalhoun/.rvm/rubies/ruby-2.2.1/lib/ruby/gems/2.2.0/gems/tzinfo-1.2.2/test/zoneinfo

这是我得到的…

sudo chown-R thomascalhoun/Users/thomascalhoun/.rvm/

工作得非常出色！祝福你！
