Pyinstaller - ImportError: No system module 'pywintypes' (pywintypes27.dll)

Question

I am trying to package my python script into an executable. I thought I would be pretty straight forward as I don\'t have very many imports. First off here are my imports:

Answer 1

Not sure if you're still looking for help on this.

Errors 1 and 3 look like the same error. This SO question pointed me in the right direction. Essentially, install the MS VC++ 9.0 x64 redistribution package, and that should take care of those errors.

Error 2 appears to have been taken care of by following Lee's suggestion.

Error 4 is because, for some reason, PyInstaller stuck some empty file names in your binary list. I'm not sure if there's a less-hacky way to fix the error, but I was able to get around it by putting

for b in a.binaries:
    if b[0] == '':
        a.binaries.remove(b)

after the Analysis( ... ) block in my spec file.

I'm not sure if the library python%s%s required via ctypes not found warnings are relevant. They're awfully suspicious, but I went down a rabbit hole trying to figure out where those warnings were generated and only succeeded in wasting about two hours of my evening.
