Pyinstaller not working - ImportError: Module 'pywintypes' isn't in frozen sys.path

[21672] Failed to execute script pyi_rth_win32api

The above is the error when I try to execute. There's not a pyi_rth_win32api anywhere in the new dist or build folders created - but it exists in \Lib\site-packages\PyInstaller\Hooks\rthooks

The date for the creation of that file in the hooks folder is today from after I ran pyinstaller, so it never existed before anywhere. Why is it creating that and trying to add it and causing the pyinstaller to fail?

Is OS outdated?

In site packages, there's are win32, win32com, win32comext, and win32ctypes directories.

None of them have pyi_rth_win32api.

Going through the text that came up when I first ran Pyinstaller, I notice some warnings that might be related?

Such as:

If anyone could please help me - I'm trying to create an executable to share a script I wrote with other users at work who do not use python.

Also - The script starts with a user input line. Not sure if that could be related?

Answer 1

Your application is missing one dll file: pywintypes37.dll
