For reference, in Chalice we catch that error: https://github.com/aws/chalice/blob/master/chalice/deploy/packager.py#L95 to expose a better message to the user: https://github.com/aws/chalice/blob/master/chalice/constants.py#L207 along with a link to the documentation about how to resolve the problem.

When sam build is called, pip tries to download all the packages in wheel format. When this failes pip tries to convert the remaining packages from sdist to wheel. For some reason this doesn't work. The solution is to install wheel with the folowing command:
pip3 install wheel

This isn't working for me. I have wheel installed in the venv where I'm working as well as in my Mac's default interpreter and I'm still getting a failure due to missing wheels.
