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")
server Start the Rails server (short-cut alias: "s")
dbconsole Start a console for the database specified in config/database.yml
(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:
application Generate the Rails application code
destroy Undo code generated with "generate" (short-cut alias: "d")
plugin new Generates skeleton for developing a Rails plugin
runner Run a piece of code in the application environment (short-cut alias: "r")
All commands can be run with -h (or --help) for more information.
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.
