AssertionError on pipenv install in ubuntu trusty docker

I try to use pipenv in a docker container based on ubuntu trusty. Basically bare metal except for some security patches like apt-get install libssl-dev, libffi-dev and pip install requests[security]

I can run pipenv but whenever I try to call pipenv install I get the following output

root@782753ee5bc0:/# pipenv install requests

Running pipenv shell --fancy circumvents the problem
