Convert .py to .exe with cmd

I was trying to convert my main.py to a exe file

I followed a tutorial on youtube i did it like it said

first open cmd in the folder

then type in pip install pyinstaller

then type in like this pyinstaller --onefile main.py
but it does’nt convert it shows this

>Solution :

While Eyal’s solution is correct, there is an easier option. Just run this:

py -m PyInstaller --onefile main.py

It could also be python -m PyInstaller --onefile main.py depending on your system configuration.
