ESP32 Arduino macOS exec: “python”: executable file not found in $PATH

Apple removed old Python 2 from macOS 12.3. Arduino ESP32 depends on Python interpreter.

Build in Arduino IDE may fail with error:

"python": executable file not found in $PATH

It’s sufficient to change name of binary to python3

Edit file

~/Library/Arduino15/packages/esp32/hardware/esp32/2.0.2/platform.txt

Change the line:

tools.gen_esp32part.cmd=python "{runtime.platform.path}/tools/gen_esp32part.py"

To line with python3:

tools.gen_esp32part.cmd=python3 "{runtime.platform.path}/tools/gen_esp32part.py"

Re-open Arduino IDE and build the project.
