`ImportError: No module named six` when creating python2 virtualenv

[hutchisr]

Creating a python2 based virtualenv appears to no longer work. Running pyenv virtualenv 2.7.17 myvenv gives the following error:

ensurepip is disabled in Debian/Ubuntu for the system python.

Python modules For the system python are usually handled by dpkg and apt-get.

    apt-get install python-<module name>

Install the python-pip package to use pip itself.  Using pip together
with the system python might have unexpected results for any system installed
module, so use it on your own risk, or make sure to only use it in virtual
environments.
