Tried pipenv for the first time few weeks ago. The first thing I do is 'pipenv install celery[redis]', fairly trivial, and I hit a critical bug. The package installs fine, but the lockfile is unusable now because of the extra. So every time I install something, i need to run sed, to remove all extras from the Pipfile.lock. And then there is the speed. pipenv is pathetically slow installing packages. And I am thinking to myself having recently read an article about how bad npm is, "Only people who never had to deal with pythons packaging mess think npm is horrible"
