Day one - SuSE factory - Why doesn't rake work?

Rails
1

What are the below rake errors telling me?

====
I’m a rails newbie, but a long time programmer SUSE user.

I’m trying get day one stuff to work where it says run rake to verify
everything is setup.

I’m a SuSE fan, so I’m trying to use SuSE 10.0.

So far everytime I run rake, it gives errors.

I’ve got a fairly simple mysql database setup that I want to work with.

Concerned that ruby 1.8.2 from SuSE 10 was too old, I’ve just
compiled/installed ruby-1.8.3 and rubygems-0.8.11 from the SUSE
factory (like Red Hat’s Fedora).

Currently when I run rake I get

rake

Usually this particular error indicates that you didn’t set up your id
field
in your table to be auto_increment. Start there and see how many other
errors go away.

Thanks,

As I said, this is my first time to run ruby/rails.

I have been trying “rake” with no options. Today I read something
that called for running “rake test”.

When I do “rake test” everything works fine.

Was that my mistake? Does “rake” by itself modify the devel DB which
in my case has some test data in it?

If “rake” should work, I’m still having problems even with the basic
ToDo setup called for in “four days on rails”. The scaffolding itself
seems to be working.

Thanks
