Warning! PATH is not properly set up...

今天發現輸入rvm -v時報警告了

Warning! PATH is not properly set up, '/.../ruby-2.2.2/bin' is not at first place.
         Usually this is caused by shell initialization files. Search for 'PATH=...' entries.
         You can also re-add RVM to your profile by running: 'rvm get stable --auto-dotfiles'.
         To fix it temporarily in this shell session run: 'rvm use ruby-2.2.2'.
         To ignore this error add rvm_silence_path_mismatch_check_flag=1 to your ~/.rvmrc file.

解決方法以下，僅供參考

rvm reset
