python - ubuntu using pyinstaller

Question

The command cannot be found. It has been installed through pip3. Ubuntu uses python3,
but it cannot be used. The online tutorial is to enter the installation location of pyinstaller, but the installation location of pyinstaller cannot be found.

Answer 1

The components installed through pip3 are Python components.
pyinstaller is a component of python.
Try the following:

python pyinstaller.py -F main.py

Answer 2

The above method is correct, but the reason why the command is not found in Linux is because you have not added the directory of the pyinstaller script to the system environment. You can search under /usr/bin/ to see if there is a python script such as pip. I am ignorant. Please don't step on it!
