You can get around this by running rake db:create db:migrate, but a more friendly error message should be possible.

    Chrome has failed me for the last time for attaching a patch.

    No tests, because there's no previous tests for rake stuff.

    +1 verified patch applies cleanly. Looks like the right error message now.

    +1 verified patch applies cleanly, addresses something I think should be fixed.

    It's worth pointing out that rails can be used without a database. Would it make sense to change the error message from:

      db/schema.rb doesn't exist yet. Run "rake db:migrate" to create it then try again.

    to

      db/schema.rb doesn't exist yet. Run "rake db:migrate" to create it then try again.  If you do not intend to use a database, you should instead alter config/environment.rb to remove active_record: config.frameworks -= [ :active_record ]

    I've attached a revised patch for consideration.

    +1 on idea and message, verified and applies cleanly on 2-3-stable and master

    sidenote: there should be a test suit for the basic included rake tasks, there are tests.

    +1 on John's message tweaks. I had thought to include a message to that effect, but figured it'd be a little too verbose. Looks fine though.

    Applies cleanly to edge Rails. But the patch needs tests.

    As I said before, there aren't any tests for ANY of the rake tasks, so starting to do that just for this one patch seems a little overwhelming.

    I frequently write rails apps with no database.

    +1 Yes, I really want this fix. I want to be reminded what to do rather than get a long stack trace that is always the same. Could there be analogous fixes for the perennial stack traces that result from not having some needed gem installed?

    patch applied to 2-3-stable. I ran the tests too, not that it makes a difference for a patch without tests.
