rails create my_app

Question

any one can give me a idea why when I try create my_app which is not working, and only showing:

usage:
    rails new APP_PATH [options]
options:
  -r, [--ruby=PATH]
  -b, [builder=TEMPLATE]...

and under my site folder, I couldn't find the my_app folder. when I open the text mate by typing mate my_app, how can I make it show the folder location?

Answer 1

If you have setup TextMate as command line tool, simply do

$ rails new my_app
$ mate my_app

and it will open the newly generated app in TextMate

Answer 2

正确的命令是rails new app_name
