"Read timed out" error while generating lock file.

Issue description

Creating the virtual environment and installing packages from pip with pipenv install is fine, but I get a Read timed out. error while creating the lock file. I’m running pipenv install numpy as the working example with Python version 2.7.12 on Ubuntu 16.04. (I do have pyenv installed but for this example the shim just points to the system python.)

Running pip list in the virtual environment shows the package installed correctly. (As does running the import statement in the python shell.) It’s just the lock file that has problems. I also tried running pipenv lock --clear with the created Pipfile, and the same error shows up.

Expected result

Clean exit and production of Pipfile.lock (not produced in practice)

Actual result

I had the same problem. This seems to have something to do with #2110 and #2193. The problem went away when I upgraded my system wide certifi from 2018.1.18 to 2018.8.13:

$ PIP_REQUIRE_VIRTUALENV=false pip3 install certifi --upgrade

what about adding a cache proxy on your machine?
