Ruby on rails RVM未设置路径变量

我正在我的计算机上运行以下命令：

rvm使用ruby-v2.1.1之后我得到了以下错误：

Using /home/sfawebuser/.rvm/gems/ruby-2.1.2 Command 'sort' is available in '/usr/bin/sort'Command 'head' is available in '/usr/bin/head'   The command could not be located because '/usr/bin' is not included in the PATH environment variable.The command could not be located because '/usr/bin' is not included in the PATH environment variable.   head: command not foundsort: command not found

看起来它正在覆盖路径值并删除/usr/bin。然后我找到了.profile文件的源文件，其中包含/usr/bin。当我再次运行上面的命令时，我得到了完全相同的错误。因此，在RVM中的某个地方，它正在执行一个导出路径=“…”，该路径覆盖了原始路径，并且不知何故忘记了包含原始路径，该路径包含/usr/bin。在执行任何rvm命令后，都必须手动查找.profile文件，这是一个恼人的问题。我看了一下代码，但有点混乱。有没有人见过这个问题以及它是如何解决的

rvm列表的输出：

Command 'awk' is available in '/usr/bin/awk'
The command could not be located because '/usr/bin' is not included in the PATH environment variable.
awk: command not found
Command 'dpkg' is available in '/usr/bin/dpkg'
The command could not be located because '/usr/bin' is not included in the PATH environment variable.

rvm rubies

/somepath/.rvm/scripts/list: line 245: sort: command not found

No rvm rubies installed yet. Try 'rvm help install'.

试试看：

rvm-reload

和

rvm-install 2.1.1

和

rvm-use 2.1.1

这么简单真是不可思议！谢谢Maringan！节省了我很多时间。。。我喜欢先自己想办法解决问题，但经过8个多小时的徒劳之后，我决定是时候寻求帮助了：-）感谢您的及时回复。
