Usage: rails COMMAND [ARGS]

The most common rails commands are:                                    
 generate    Generate new code (short-cut alias: "g")                  
 console     Start the Rails console (short-cut alias: "c")

             (short-cut alias: "db")                                   
 new         Create a new Rails application. "rails new my_app" creates a                                                                      
             new application called MyApp in "./my_app"                

In addition to those, there are:   
 destroy      Undo code generated with "generate" (short-cut alias: "d")

All commands can be run with -h (or --help) for more information.

And when I run bundle exec rake rails:update:bin It show the error message below

From here:

Actually it's spring which cause this issue. Try to comment it in the Gemfile, then bundle install and restart the server ; shutting it down, the warning is not present anymore.
