Repro Steps

1. Install an app via aio app init
2. Choose Standalone Application
3. Uncheck Events and Web Assets

Investigation

python v2 is no longer installed with macOS 12.3 Monterey and greater: https://developer.apple.com/documentation/macos-release-notes/macos-12_3-release-notes#Python

Workaround

To get rid of this error, users have to either:

1. install python v2 manually: https://www.python.org/downloads/release/python-2713/
2. symlink an existing python@3 (may cause issues): https://dev.to/malwarebo/how-to-set-python3-as-a-default-python-version-on-mac-4jjf
3. Configure their python for node-gyp (after installing python@3): https://github.com/nodejs/node-gyp#configuring-python-dependency

Fix

This has to be fixed via wskdebug, perhaps there is an update in their dependencies that will not require python 2.

Note: this is an optional dependency of ssh2 (via wskdebug), and doesn't affect wskdebug functionality AFAIK
