pywin32 compatibility error

[mayankpj@…]

I am using "pywin32-217.win32-py2.7.exe" with script built on python 2.7, I get warning while buiding:

8160 WARNING: pythoncom is changing its name to pythoncom27
8191 WARNING: pywintypes is changing its name to pywintypes27

The dist directory contains files: "pythoncom27.dll" and "pywintypes27.dll"

runnning the executable gives following error:

Traceback (most recent call last):
  File "<string>", line 65, in <module>
  File "C:\pyinstaller-2.0\PyInstaller\loader\iu.py", line 386, in importHook
    mod = _self_doimport(nm, ctx, fqname)
  File "C:\pyinstaller-2.0\PyInstaller\loader\iu.py", line 480, in doimport
    exec co in mod.__dict__
  File "C:\pyinstaller-2.0\LnT_Model\build\pyi.win32\LnT_Model\out00-PYZ.pyz\win32com", line 6, in <module>
  File "C:\pyinstaller-2.0\PyInstaller\loader\iu.py", line 409, in importHook
    raise ImportError("No module named %s" % fqname)
ImportError: No module named pythoncom

I have read that installing pywin32 version 212 resolves the issue, but they did not release exe installer for python 27. Any help will be appreciated.

PyInstaller? is renaming these modules and adding 27 to then. It is really ancient code and I'm not sure why it is doing. We need to verify that. Could you post here any code example?

I import a library called pandas, simple script with just one line can be used to reproduce the error:

import pandas as pd
print "Hello World!"

I had posted the problem with pandas developers on ​https://github.com/pydata/pandas/issues/1787 but have received no replies as of now.

One thing I do not understand is why it is picking up modules pythoncom and pywintypes. Somehow pyinstaller is not processing hooks for pythoncom but it includes it's runtime hook part.

Could you please as a workaround try the following code in your app?

import pythoncom

[matysek]

Could you please try latest dev version? I think it should be fixed there now.

dear matysek,

I have tried with developer version of pyinstaller and the latest version of pandas with python 2.7.2.

A one line script "import pandas" did not work either. I also noticed that using xlrd and some other modules in my script also produce warning about pythoncoms but still runs OK on various systems.

[matysek]

The following message should be now gone.

WARNING: pythoncom is changing its name to pythoncom27

Do you experience now a different error or is it still the same?

If you are experiencing a different error then it is probably related directly to pandas and not to pythoncom module. In this case please open a new bug report related to panda.
