Did the install of mkdocs-material succeed? On Mac OS you have to install with sudo or with the flag --user. Otherwise it won't work (at least on my machine).

Closing due to inactivity. If you still experience this problem, please post it on the MkDocs issue tracker, as I suspect it is not specific to the Material theme.

I had the exact same error, and squidfunk's suggestion worked. I simply:
sudo pip uninstall mkdocs-material
pip install mkdocs-material --user
