Start by reproducing `!pip install wget` in the Python 3.7 Carnets environment and inspect the reported pip/pkg_resources conflict-check traceback. Determine whether installation actually fails or only emits an error after succeeding; done means the command completes without the traceback and the installed module remains usable.
