Hi there, since Apple upgraded MacOS Monterey to 12.3 Arduino is not able to find python - apparently there is no more python 2.7 in MacOS. But installing python 3 and making sure it is in $PATH does not help much - still the problem is: Arduino - or as I was told on Arduino Gighub page - ESP32 part…

[image] Python Releases for macOS The official home of the Python Programming Language I would install the latest Python 2 AND Python 3 from here. % which python /usr/bin/python % python -V Python 2.7.18 % which python3 /Library/Frameworks/Python.framew…

true, but the thing is not WRONG python (3 instead of 2) but LACK of python - not visible by the environment variables and I opened the ticket with Arduino - they told me: "Arduino does NOT use python but the manager for ESP uses" so ticket was closed today

actually I made a link to/opt/homebrew/bin/python not /usr/local/bin/python but since both paths are in $PATH it should not make a difference papio@MBP16M1papio ~ % ls -la /opt/homebrew/bin/python* | grep -v config lrwxr-xr-x 1 root admin 25 15 Mar 15:06 /opt/homebrew/bin/python -> /opt/homebre…

I confirm, my ESP32Cam uses this library : gen_esp32part.py

I think entire ESP IDF is based on python :wink:

Yes, another question maybe gen_esp32.py needs absolutely python 2 , reason why compiler asks for additional command line features ? Is it possible to re-install python2 on monterey 12.3 with homebrew ?

I have the same problem in Windows 10 Arduino IDE 2.0 RC-5

MacBook Air (Intel), Monterey 12.3 1. instal Homebrew: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" 2. instal Python2: brew install python@2 3. don't start Arduino from GUI!!! open terminal type: open /Applications/Arduino.app no more error…

I have installed Python 2.7.18 with your tip , and it works when I launch Arduino.app with Terminal. Thanks

Couldn't install python@2 with my Macbook Air M1. however it worked after johnwasser's advice (here above), Python 2.7.18 and Arduino.app launch thru Terminal. Thanks zyghom, nadym and johnwasser for all these posts.
