When you froze edge did you remember to re-run the rails command? Depending on how long ago it was when you generated your app some of the script files, as well as environment files, could be out of date.
From the root of your application execute: “ruby vendor/rails/railties/bin/rails .”
I just created a new project using "ruby vendor/rails/railties/bin/
rails" inside my freezed rails and even this new version didn't
started, got the same errors!
I never would guess this.
I couldn't run ruby script/about but then I "freezed" again, saw the
active_resource code was downloaded and everything works fine now.
