Description:
    The 'rails new' command creates a new Rails application with a default
    directory structure and configuration at the path you specify.

    You can specify extra command-line arguments to be used every time
    'rails new' runs in the .railsrc configuration file in your home directory.

    Note that the arguments specified in the .railsrc file don't affect the
    defaults values shown above in this help message.

Example:
    rails new ~/Code/Ruby/weblog

    This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
    See the README in the newly created application to get going.

any ideas?

It sounds like your rails executables have been removed therefore rails is no longer knows it's in a rails project directory. Which version of rails are you using? Could you post your project directory structure.

As a first step try regenerating the binstubs:

$ rake rails:update:bin

Thanks for the offer PaulM wht threw me was I'd done nothing to change any of the project structure or that. rake db worked. In the end I did a lot of stuff but uninstalled and reinstalled ruby and rails and homebrew etc still didnt work. make a new app and that worked. So ended up having to revert back to a older part of the project
