Quick install pyinstaller

Open cmd on the computer and enter the following line:

pip install pyinstaller==4.10 -i https://pypi.doubanio.com/simple

Choose the installer version to download according to your own needs, I downloaded pyinstaller==4.10

If you don't know what version you need, you can enter pip install pyinstaller in cmd first (this can also be downloaded, but errors often occur, and it is not recommended to download relatively large packages in this way) and you can see the downloaded version, or in View in settings in pycharm .

The result of the operation is as follows:
