Problem

pipenv install requests fails

Expected result

requests is installed
OR
a clear error message is shown

Actual result

When possible, provide the verbose output (--verbose), especially for locking and dependencies resolving issues.

Steps to replicate

Using python:3.6.5 official Docker image

# docker run --rm -it python:3.6.5 bash

[techalchemy]

This happens when you try use pipenv to create a virtualenv from the root directory. This is not an intended usage and is an edge case. We have plans to improve the messsaging here

[janzankowski]

+1 to fixing this. Very cryptic indeed.

[Kilo59]

Have there been any updates for this problem?

[techalchemy]

We don't vendor pip 9 and we have improved error messaging so I would have to suggest upgrading pipenv if you encounter this and filing a new issue if it persists

Still encounterning cryptic errors with version 2018-11-26. What version was this fixed in?
