Py: The command pyinstaller could not be found

Question

I am trying to convert a script to an executable with pyinstaller, but pyinstaller won't work.

I've tried installing it for 3.8 and 3.7, but neither works. How do I know what versions pyinstaller is available for, or what am I doing wrong? It just tells me that there is no command called pyinstaller.

Commands I tried:

pyinstaller --onefile main.py

pyinstaller.exe --onefile main.py

py -3 pyinstaller --onefile main.py

py -3 pyinstaller.exe --onefile main.py

py -3.7 pyinstaller --onefile main.py

py -3.7 pyinstaller.exe --onefile main.py

py -3.8 pyinstaller --onefile main.py

py -3.8 pyinstaller --onefile main.py

If on Unix-like OS (Linux, *BSD, probably MacOS): https://superuser.com/questions/1310800/pyinstaller-command-not-found

If pip says the module is installed, the binary is somewhere on your system. On most *nix systems, you can use the find command. On windows, the where command should do something similar . Once you find it, you can create a symlink or copy it to a directory where you or the OS can find and run it.

If pip is having trouble installing it, that's a completely different issue. If the above solution doesn't work, paste the output of pip install pyinstaller into a new question about pip failing to install pyinstaller rather than the OS being unable to find pyinstaller.
