I typed -m pip install --upgrade pip in the right directory to upgrade and I get an error saying

When I try to do pyinstaller in command prompt this happens:

C:\Users\Stevie>pyinstaller
'pyinstaller' is not recognized as an internal or external command,

Anyone know why?

Answer 1

直接在命令提示符中（不在 Python 解释器中）输入python -m pip install --upgrade pip

Answer 2

you should first try pip freeze to see if pyinstaller is installed by pip If it is installed, try

pip uninstall pyinstaller
pip install pyinstaller
