py2exe: "ImportError: No module named pywintypes" ...?? :-(

P: n/a
Hi,

I have a small test to "compile" al litle script as a WMI-Tester. The
script include a wmi-wrapper and "insert" the Win32-modeles.

here the code:

my "WMI-Tester.py"
-----
import wmi
computer = wmi.WMI ()
for item in computer.Win32_Process ():
print item
-----

the WMI-Wrapper
----
....
import win32com.client
import pywintypes
....
=> look at http://tgolden.sc.sabren.com/python/wmi.html
-----

the py2exe-setup.py
-----
from distutils.core import setup
setup(name="WMI_tester", scripts=["WMI_tester.py"],)
-----

and the error at
"setup.py py2exe":
running py2exe

ImportError: No module named pywintypes

In the python-enviroment works the script fine - why the
import-error???

Hi,

here the code:

my "WMI-Tester.py"
-----

computer = wmi.WMI ()
for item in computer.Win32_Process ():
print item
----- Ok. After installing wmi.py and rebooting my machine, this works for me
when run from Python.
the py2exe-setup.py
-----
from distutils.core import setup
setup(name="WMI_tester", scripts=["WMI_tester.py"],)
----- This script is not complete (but certainly a cut and paste error), you
have to add 'import py2exe'.

It seems that either your installation is corrupted or py2exe doesn't work with
ActiveState Python any longer, py2exe 0.4.1 requires a fairly new build
of the win32 extensions (154 or later, IIRC). Mark changed the way the special
pywintypes and pythoncom extensions are imported.
For me (Python 2.2.2, and a recent win32all) the py2exe build process
runs successfully.

The deeper problem occurs when the executable is run:

c:\wmi\dist\wmi-tester>wmi-tester.exe
Traceback (most recent call last):
File "<string>", line 1, in ?
File "imputil.pyc", line 103, in _import_hook

File "imputil.pyc", line 216, in import_top
File "imputil.pyc", line 271, in _import_one

File "wmi.pyc", line 117, in ?

File "<string>", line 70, in _finish_import
File "imputil.pyc", line 318, in _load_tail
ImportError: No module named win32com.gen_py

That is because the wmi module uses early binding to get some COM
constants described in a type library. For this, one would need to use
the --progids option to py2exe, so that the win32com.gen_py directory
which contains the makepy output is included into the exe.

Unfortunately this only works for *modules* in this directory, and not
(yet?) for packages, but wmi requires/creates a package named
565783C6-CB41-11D1-8B02-00600806D9B6x0x1x2 here, and I cannot come up
with a quick hack right now, neither do I know how to guess this name.

And I don't even find docs for win32com.client.GetObject("winmgmts:").
How can I, from this call, find out the typelib guid and version?

Also, I'm not sure if it is a good idea to include the makepy generated
modules into the executable. Maybe it would be better to create them at
runtime in a subdirectory (and include the makepy module into the exe).

Can anyone help?
