Hi, I’m trying to make a ‘HelloWorld App’, but i’m stopped with this problem, after typed ‘rails server’ i get this message:
"$: ~/TRAINING/Ruby/hello/hello_app$ rails server
bin/rails:6: warning: already initialized constant APP_PATH
/home/juanjo/TRAINING/Ruby/hello/hello_app/bin/rails:6: warning: previous definition of APP_PATH was here
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:
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. "
what is the problem ? why can’t start rails server?
Thanks.
