macOS 12.3 Beta has removed the Python 2 support: spawn /usr/bin/python ENOENT

• Electron-Builder Version: 22.13.1

• Node Version: v16.13.1

• Electron Version: 16.0.8
• Electron Type (current, beta, nightly): current

• electron-updater Version: 4.6.5

• Target: macOS (x86, ARM64, universal?)

macOS 12.3 has removed the Python 2 support; thus, /usr/bin/python has been removed. electron-builder tries to call /usr/bin/python and it throws Error: Exit code: ENOENT. spawn /usr/bin/python ENOENT.

Reproducible Step

Ok, it’s working again in version 23.0.2, thanks.

Hi, on MacOS 12.3.1 Chip M1 Pro, I did the following procedures: 1 - Use ASDF to install python v2: asdf install python 2.7.18 2 - Set Python on shell with asdf: asdf shell python 2.7.18 3 - Export PYTHON_PATH environment: export PYTHON_PATH=/Users/YOUR_USER/.asdf/shims/python

Bingo! Now I can create the .DMG again.

Hope this helps someone else who has gone through this too.
