Pipenv locking taking forever

[aapeliv]

$ pipenv install
Pipfile.lock (b9c44e) out of date, updating to (ec4b23)...
Locking [dev-packages] dependencies...

Then it gets stuck for quite a while.

This is a rather well known issue:
pypa/pipenv#356
pypa/pipenv#1914

You can issue the command --skip-lock to speed things up

When there's a variety of installation candidates it's quite slow. This is something we could improve by pinning some versions of packages.

I'll take a look at pinning some of the package versions.
