Pipenv requires existing folder ~/.local/share/virtualenvs

[tcwalther]

Issue description

When running the current commit 51cbc2e of pipenv in a Docker image (like python:3.6), one has to manually create the folder /root/.local/share/virtualenvs for pipenv to work.

Expected result

root@851be9e3b8d1:/tmp# pipenv install requests
Creating a virtualenv for this project…
Pipfile: /tmp/Pipfile
Using /usr/local/bin/python (3.6.6) to create virtualenv…
...

Actual result

root@851be9e3b8d1:/tmp# pipenv install requests

Steps to replicate

docker run -it --rm python:3.6 bash
# inside the container
pip install git+git://github.com/pypa/pipenv.git@51cbc2e2f76a7c60f879a608fd96e95faca35f2e
pipenv install requests

To fix:

# inside the container
mkdir -p /root/.local/share/virtualenvs

I’d assume the solution would be to create ~/.local/share/virtualenvs to make sure it exists.

@uranusjr Can I take this up?

[uranusjr]

sure, go ahead

[Enzime]

@sinscary are you still working on this one or can I take it up?

[sinscary]

@Enzime I didn't get time to look at this. You can take it up 👍
