How to fix “‘jupyter’ is not recognized as an internal or external command, operable program or batch file” when running Jupyter on Windows?

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 ' "


Errno 'THIS_PROGRAM' not found
