pipenv: Unable to install package in container

I was troubleshooting an opened bug (https://github.com/pypa/pipenv/issues/1639) that I seem to have run into. In trying to reproduce it, it seems like i bumped into another issue.

This looks similar to the closed https://github.com/pypa/pipenv/issues/1441 issue, however, the command virtualenv --python=python3 myenv did not error out as anticipated in the comments.

Expected result

I expected to see a Pipfile and Pipfile.lock in the /tmp/test1 directory.

Actual result

Saw the strack trace above.
