$PATH is not properly set up

问题

I just ran 'rvm get stable' to be given the below error;

Warning! PATH is not properly set up, '/Users/jamesbkemp/.rvm/gems/ruby-2.2.1/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-2.2.1'.

Previous to running 'rvm get stable' I ran 'brew upgrade ruby' to Ruby 2.2.2.

'echo $PATH' returns the below:

/usr/local/heroku/bin:/Users/user/.rvm/gems/ruby-2.2.1/bin:/Users/user/.rvm/gems/ruby-2.2.1@global/bin:/Users/user/.rvm/rubies/ruby-2.2.1/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Users/user/.rvm/bin:/Users/user/.rvm/bin

I don't understand what the issue is here or why when i run 'ruby -v' it returns 'ruby 2.2.1p85'.

Running 'rvm list' returns the below, as well as the same PATH error message detailed above;

ruby-2.0.0-p353 [ x86_64 ]
   ruby-2.0.0-p451 [ x86_64 ]
   ruby-2.1.0 [ x86_64 ]
   ruby-2.1.5 [ x86_64 ]
=* ruby-2.2.1 [ x86_64 ]
   ruby-2.2.2 [ x86_64 ]

Can anyone help?

回答1:

Put RVM code at the start of $PATH

I just had the same problem. I went to terminal and entered subl ~/ which opens up your home folder on Sublime Text (or you can use another text editor).

I then clicked on every file starting with ., e.g. .bash_profile, .bashrc, .mkshrc, .zshrc

Whenever I saw this line:

export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting

I changed it to this:

export PATH="$HOME/.rvm/bin:$PATH" # Add RVM to PATH for scripting

That way, the RVM code is at the start of $PATH. Then I quit Terminal and started it up again to make sure those config files were loaded.
