When i try to run the samples/robotbenchmark/squar_path example I first got the message:
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of Webots will drop support for Python 2.7.

While a Python 3.7 version
python --version
Python 3.7.4
is available via my Macports environment
port version
Version: 2.5.4
So I think that Webots doesn't use the settings from my macports profile - how could i achive this? I tried setting the python path to
/opt/local/bin/python
in preferenes/general but then I ended up with a complaint:
ImportError: dlopen(/Applications/Webots.app/lib/python37/_controller.so, 2): Library not loaded: /Library/Frameworks/Python.framework/Versions/3.7/Python
And I have not seen an option to specify the library path ...
The library path is not recognized /Library/Frameworks/Python.framework/Versions/3.7/Python does not exist but the /opt/local//Library/Frameworks/Python.framework/Versions/3.7/Python one does ..
So as a workaround in /Library/Frameworks i did a
sudo ln -s /opt/local/Library/Frameworks/Python.framework .
Now the robot starts...
