How can I fix "'jupyter' is not recognized as an internal or external command, operable program or batch file" when running Jupyter on Windows?

I have installed Jupyter on Windows 10, Python 3.x via pip install jupyter The installation works fine, even though I did restart the terminal. But trying to run jupyter notebook gives the following error 'jupyter' is not recognized as an internal or external command, operable program or batch file. How and where do I find the executable for Jupyter?
If you are absolutely sure that your Python library path is in your system variables (and you can find that path when you pip install Jupyter, you just have to read a bit) and you still experience "command not found or recognized" errors in Windows, you can try: python -m notebook For my Windows at least (Windows 10 Pro), having the python -m is the only way I can run my Python packages from command line without running into some sort of error: Fatal error in launcher: Unable to create process using ' " or Errno 'THIS_PROGRAM' not found
