When I run rake db:create:all, I’m getting the following message:

rake aborted!
stack level too deep
And the database is not created. Can someone help me?

The stack level too deep error occurs also, if you want to destroy a record and you have an association with :dependent => :destroy to another model. If the other model has a association with :dependent => :destroy back to this model, the stack level is too deep, too.
Rake is a utility built into Ruby and Rails, which provides an efficient way for managing database changes. You can easily migrate database changes to servers by only using a command line!
db:reset: Resets your database using your migrations for the current environment. It does this by running the db:drop , db:create , db:migrate tasks. db:rollback: Rolls the schema back to the previous version, undoing the migration that you just ran. If you want to undo previous n migrations, pass STEP=n to this task.
rake is a Make-like program implemented in Ruby. rails is a web framework, which also has some rake tasks. This means that you can have a ruby program with rake but without rails, but not the other way around. By itself, rake will be faster because you don't need to load the whole rails application.
I've found another way to do not have to run bundle exec every time.
For myself, working w/ Sinatra (not Rails), adding gem 'rake' to my Gemfile worked like a charm. :)

I found a hint on the internet how to avoid the error. See the link to "Rail 3.1 and Rake aborted". There is given no reason, but to use bundle exec rake instead of the pure rake call has done the trick there. Seems like the call for rake is calling itself recursively, without having noticed that the files are yet loaded.
So give it a try and tell us if that worked for you.

If, like me, you are too lazy to use bundle every time:
Want to see a magic trick? Try running gem uninstall rake. Confirm when asked about broken dependencies. Counter-intuitive, I know.
Now run your rake command without bundle exec. Magic!
I don't know how it really works, but I'm thinking it has something to do with your local/global gemsets; your rvm global rake should be the one being used now.
No, this may not good practice, but like I said, it's for the lazy.
