'rails' command creates directory with /vendor/rails which uses wrong version of rails
by kalfa in Programming Languages

For some reason when I run rails command, it installs 2.2.3 version of Rails in /vendor/rails and webbrick uses that version instead of 2.3.5 which is installed as a gem.

If I delete that, then it uses the right directory. I remember using git submodule once, but I don't think that has anything to do with this.

How can I correct this? Thanks

How do I figure out why errors are occurring when running unit tests on app that is being upgraded from Rails 2.3 to Rails 3.0?
by Hosein Mohtasham in Programming Languages

I've been tasked with upgrading an app from Rails 2.3.5 to 3.0.19. This also involves upgrading Ruby from 1.8.6 to 1.8.7. After this upgrade is complete and stable, the plan is then to move to Ruby 1.9 and Rails 3.2.

Gems (output from bundle install), fyi:

Using rake (10.0.3)
Using abstract (1.0.0)
Using activesupport (3.0.19)
Using build
