• I have searched the issue tracker and believe that this is not a duplicate.

Make sure you run commands with -v flag before pasting the output.

Steps to reproduce

Initialize and then add xlwings

pdm init
pdm add xlwings

import xlwings as xw in py file

Actual behavior

Get the error that pywintypes could not be found afterimport xlwings

Traceback (most recent call last):
  File "e:\Code\pdm-test\test.py", line 1, in <module>
    import xlwings as xw
  File "e:\Code\pdm-test\__pypackages__\3.9\lib\xlwings\__init__.py", line 9, in <module>
    from . import _xlwindows as xlplatform
  File "e:\Code\pdm-test\__pypackages__\3.9\lib\xlwings\_xlwindows.py", line 14, in <module>
    import pywintypes
  File "e:\Code\pdm-test\__pypackages__\3.9\lib\win32\lib\pywintypes.py", line 117, in <module>
    __import_pywin32_system_module__("pywintypes", globals())
  File "e:\Code\pdm-test\__pypackages__\3.9\lib\win32\lib\pywintypes.py", line 98, in __import_pywin32_system_module__
    raise ImportError("No system module '%s' (%s)" % (modname, filename))
ImportError: No system module 'pywintypes' (pywintypes39.dll)

Expected behavior

After installing xlwings, can find pywintypes39.dll in __pypackages__\3.9\lib\pywin32_system32\, it should be imported correctly
