pip version in venv is old, doesn't support --require-hashes

When I create a new venv, the version of pip installed is really old (1.5.6). How do I update this?

OS Type: #CentOS Linux release 7.0.1406 (Core) Python version: $ python -V: Python 2.7.5 Pipenv version: $ pipenv --version : pipenv, version 8.2.7

Expected result

I expected that if the embedded pip version wasn’t the latest, that I could somehow update it.

Actual result

The version of pip is still really old:

$ pipenv --update All good! $ pipenv run pip --version pip 1.5.6 from /home/user/.local/share/virtualenvs/pipenv-iAtZuLQ4/lib/python2.7/site-packages (python 2.7)

This really really old pip version also means I can’t install from the lock file, as it uses a pip flag that doesn’t exist in this version:

Hi @scott-burgess! That’s odd. What is the version of pip installed with your system python(s)? You should be able to run pipenv run pip install --upgrade pip to upgrade the virtualenvs pip to the latest version.

Same issue, but instead caused by having an outdated system virtualenv (my system pip was fine). Solved with sudo pip install virtualenv --upgrade
