Well, I gave a specific example in Rails, using DB migrations against a shared DB. It’s not an unsolvable problem, and of course each dev can have their own DB, but if this is poorly managed it’s easy to become unwieldy. Outside of that, if many devs are constantly making dependency changes such that every time you “git pull” you have to rebuild environments, etc. Maybe devs are adding features but not prepopulating dev environments with sensible test data so your dev environment gets horked. Etc etc. Its not usually about merging the code itself.
