“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

You should install the graphviz package in your system (not just the python package). On Ubuntu you should try:

sudo apt-get install graphviz
