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

I had a similar problem:

Traceback (most recent call last):
  File ".\install\pywin32_postinstall.py", line 605, in 
    install()
  File ".\install\pywin32_postinstall.py", line 328, in install
    LoadSystemModule(lib_dir, "pywintypes")
  File ".\install\pywin32_postinstall.py", line 166, in LoadSystemModule
    mod = imp.load_dynamic(modname, filename)
ImportError: DLL load failed: The specified module could not be found.

My mistake was that I installed pywin32 via pip for user

pip install pywin32 --user

So the needed DLLs were in user's AppData: %appdata%\Python\Python27\site-packages That's why pywin32_postinstall.py couldn't find them.

Re-installing without --user option helped.
