pipenv install is very slow

See original GitHub issue

Running pipenv install after changing one dependency takes about ~5 minutes for me, on a windows 10 machine with an SSD.

The vast majority of that time is spent inside Locking [packages] dependencies...

It seems like there might be some quadratic-or-worse complexity in this step?

I’ve included most of our pipfile below, but I had to remove some of our private repo dependencies:

Why are all the issues to this topic closed? I can’t pipenv install a single thing due to the lock-step hang.

Right now for me it is not slow, it is freezing…

A pipenv install my_package or a simple pipenv install does not give me any output, after 20 minutes.

EDIT: Confirmation, still nothing after a few hours. Is it the same problem? Usually it was slow, but it ended after 5 to 10 minutes.
