pyinstaller: command not found

ubuntu18.04 successfully installed pyinstaller

sudo pip3 install pyinstaller

, But execute the command: pyinstaller -F temp.spec but it prompts that the command cannot be found

I searched for some solutions on the Internet, mainly the path and download the source code to install, I feel troublesome to uninstall and reinstall

sudo pip3 uninstall pyinstaller
sudo pip3 install pyinstaller

Just execute it again
