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.
I had the same error even with no anaconda installed. After a few minutes i realized that i was trying to create a virtualenv folder (C:/myname/virtual_folder) at the same directory level as was my Python installation folder (C:/myname/python27) .
So I just created a folder and then inside of it (C:/myname/prefolder/..) i run ("virtualenv virtual_folder") with no issues .
Removal of ~/.pydistutils.cfg worked for me.

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.
I have the same problem. The reason was with invalid path of python. Fixed it with removing python to 'c:\python37' from appdata. It cuz you have unicode chars in the path name.
I had this same issue while installing requirements from requirements.txt
.
This was what solved the problem for me.
pip install --upgrade virtualenv
pip install --upgrade pip
After doing this, if you ever get errors while trying to install a dependency like below

Then use pip --no-cache-dir install <package-name>
to install the package; where <package-name>
is the name of the package you want to install.
e.g pip --no-cache-dir install pbr
You can get virtualenv to work with conda if you downgrade python to 2.7.9:
$pip install python=2.7.9
