I'm getting the ModuleNotFoundError: No module named 'lxml' while trying run a python script in Mac os. 
I've installed python in /usr/local/bin. All the libraries are also successfully installed. 
I tried setting the PATH to include the location where the libraries are installed, but it didn't help. Please advise.
This is fixed by setting the PYTHONPATH Variable in OS X.
