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

I tried for hours, read lots of posts and finally find a way out.

pip uninstall virtualenv conda install virtualenv

The reason is the virtualenv installed by pip is not compatible with conda. I don't know more details, but it works for me.
