Rails 3.0 & Ruby 1.9.2rc: Rake commands return 'already initialized constant' & stack level too deep errors. Any ideas

Question

Answer 1

bundle exec bash works for me

Answer 2

Looks like a strange recursive require.

Did you try uninstalling all versions of rake and reinstalling it? There is a bug in 1.9.2rc affecting gem loading, so that might be it? I didn't look closely into it as many people are already following it closely...

Note: The 1.9.1 is the API version, so it is correct.

I had a .bundler folder on my root directory which was conflicting. Removing it did it for me.

rm -rf ~/.bundler

I'm afraid the easier solution is running this command instead of rake db:migrate

bundle exec rake db:migrate

Answer 5

If you have RVM installed, this issue can start to occur once you update rubygems to 1.8.15. The issue was that I had rake installed in the global gemset and my project's gemset. The solution was to have only one installation of rake. To delete it from the project gemset: 1. cd to the project 2. gem uninstall rake

Update to latest Rails minor version. So if you are at 4.2, update => 4.2.latest.
