“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

Just add below to your Environmental Variable(system) PATH on Windows

C:\Program Files (x86)\Graphviz2.38\bin

there, you can find .exe files

If not work

Find Graphviz2.38/bin folder in your Program Files not in python lib

Then, add to your PATH

It's important to find a folder where .exe files exist
