Information

It would be nice if pipenv worked with this library. Right now, it gets stuck on the Locking... phase of pipenv (for a very long time, maybe hours). With the debug flag -v turned on, it shows a ton of Google Python libraries being installed during this time. It might be trying to rebuild the world instead of using binaries.
