Error creating installation package for SWMM

[barrc]

I am following the instructions here: https://github.com/USEPA/SWMM-EPANET_User_Interface/wiki/Create-Installation-Package-for-Windows-10-(python-3-Qt-5-version), using current dev-ui-py3qt5.

I installed pyinstaller, then removed the files listed in step b. When I got to the step

pyinstaller --clean frmMainSWMM_py3qt5.spec

it failed with this traceback:

@TongZhai this is the issue I had when I tried to build the installation package. It sounded like you may have run into a similar issue in the past -- any advice?

This is the symptom caused by having PyInstaller v3.6. As noted in the wiki page "Create Installation Package for Windows 10 (python 3 Qt 5 version)", updated April 1, 2020:

*Note, PyInstaller 3.6 did not work successfully in this process -- possibly due to a bug in that version -- but PyInstaller 3.4 works, so that is the recommended version."
