The name of the Python 3 executable is python on Windows, but python3 everywhere else (don't ask why). This makes it a hell to run a Python 3 script from package.json scripts. This package introduces the run-python3 command that runs the correct Python 3 executable on all platforms.
Install the package.
npm install run-python3
Use it in package.json scripts:
...
"scripts": {
"command": "run-python3 my_cool_python_script.py"
},
...
