Warning! PATH is not properly set up, '/home/ly/.rvm/gems/ruby-2.0.0-p598/bin' is not at first place, usually this is caused by shell initialization files - check them for 'PATH=...' entries, it might also help to re-add RVM to your dotfiles: 'rvm get stable --auto-dotfiles', to fix temporarily in this shell session run: 'rvm use ruby-2.0.0-p598'.
请问,这个 rvm 的警告怎么消除
