If rails server fails to start for you due to APP_PATH issue below:
Navid:someapp navid$ rails s => Booting WEBrick => Rails 4.1.0 application starting in development on http://0.0.0.0:3000 => Run `rails server -h` for more startup options => Notice: server is listening on all interfaces (0.0.0.0).

I was able to fix the above issue in two ways:
You can either comment out the spring gem or do the following instead, which I recommend:
From within your project directory, do the following:
Do the following at your own risk!!! Keep a backup of your project directory before you start doing this.
Copy off your rails and rake scripts just in case or back up your entire project directory
cp bin/rails /tmp/rails (or some other directory) cp bin/rake /tmp/rake (or some other directory) rake rails:update:bin spring binstub --all
‘rails server’ command should work for you now.
