Virtualenv OSError - setuptools pip wheel failed with error code 1

Question

I get the following error message when trying to set up a virtual environment with virtualenv 15.0.2 but receive OSError setuptools pip wheel failed with error code 1.

Answer 1

Running

conda install -c anaconda virtualenv=15.1.0 

worked for me.

This is because virtualenv doesnt work with pip while conda exists on your system.
