“RuntimeError: Make sure the Graphviz executables are on your system's path” after installing Graphviz 2.38

Question

I downloaded Graphviz 2.38 MSI version and installed under folder C:\\Python34, then I run pip install Graphviz, everything went well.

Answer 1

import os
os.environ["PATH"] += os.pathsep + "/Macintosh HD⁩/anaconda3⁩/lib⁩/⁨python3.7⁩/site-packages⁩/sphinx⁩/templates⁩/graphviz"

This solved the PATH issue on MAC for me!
