import pywin32==225 failed

[AndrewTsao]

Hi, I install latest pywin32(pywin32 ==225) module, import failed. This is my python and os information.
Python 3.6.4 |Anaconda, Inc.| (default, Jan 16 2018, 10:22:32) [MSC v.1900 64 bit (AMD64)] on win32
This is error case.

Does import pywintypes work? If not, is it possible there's a pywintypes36.dll in your c:\windows\system32 directory?

I observe a similar problem with Python 27 ( here with a fresh pywin32==225 installation in a new virtualenv )

I install pywin32 in venv, import pywintypes ok, it's from anaconda site-packages.

I find that pywin32.pth append to sys.path, after Anaconda3's path. so import pywintypes from anaconda's libs.

Does Anaconda come with a pywin32 version? It looks like that pywintypes36.dll isn't the one from pywin32 225, which would explain the issue.

>>> import pywin32
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'pywin32'

There's no 'pywin32' module in the package, so that's expected.

What is pywintypes.__path__ after you import it? I can't reproduce this problem locally, but can if an old copy of pywintypes is loaded.

I am receiving the same error with 225 in a fresh Tox virtual environment. No issue in 224; not using Conda or anything exotic.

[stephanema]

I have the same Problem starting a script on windows python 3.7.4. 64 bit.
With 224 no problems, with 225 I get:

    import win32com.client
  File "D:\programme\python37\lib\site-packages\win32com\__init__.py", line 5, in <module>
    import win32api, sys, os
ImportError: DLL load failed: Die angegebene Prozedur wurde nicht gefunden.

I switched back to 224 for now.

[mhammond]

See my above comment - I can only reproduce this if there's an old pywintypesXX.dll around. No one has yet answered my question above re pywintypes.__path__ - so there's literally nothing I can do at the moment to help with this issue.

On AWS Windows AMIs pywintypes.__file__ is C:\Program Files\Amazon\cfn-bootstrap\pywintypes27.dll

pywintypes.__path__ returns AttributeError: 'module' object has no attribute '__path__' as the comment above mentions.

[mhammond]

On AWS Windows AMIs pywintypes.__file__ is C:\Program Files\Amazon\cfn-bootstrap\pywintypes27.dll

Thanks for that info - that file will need to be replaced with the one that comes with pywin32-225. There's no way for the pywin32 installer to do that because it doesn't know that path exists.

[azoellner]

But possibly it could be solved by prepending instead of appending the pywin32_system32 in the file pywin32.pth, so that the pywin32's own DLLs will be found first. See my comment #1399 (comment).

[mhammond]

Possibly, although when I struck this issue locally, that didn't solve it for me. But yeah, I guess it can't hurt. There's also #1417
