The .venv directory is created and subsequent use of pipenv install [package] work correctly.

Relevant package versions:

delegator.py==0.0.7
pexpect==4.2.1
pipenv==0.2.8
virtualenv==15.1.0

It would be good to make a reference to PIPENV_TIMEOUT environment variable in that exception.

Got similar problem with timeout. It waited for around 20 minutes, then failed:
