Windows – How to install the win32com python library

microsoft-outlookpythonwindows

I am trying to install the win32com module. I know I should download the Python for Windows extension, but it does not work.

After I have installed Python for Windows and try import win32com.client, I get the following error message:

>>> import win32com.client

    Traceback (most recent call last):
      File "<pyshell#2>", line 1, in <module>
        import win32com.client
      File "C:\Python27\lib\site-packages\win32com\__init__.py", line 5, in <module>
        import win32api, sys, os

ImportError: No module named win32api

Trying to google for help on how to install win32api for Python does not help either; I am just referred to the Python for Windows extensions again.

Best Answer

  1. Start a command line with admin rights.
  2. python -m pip install pywin32
  3. C:\Program Files\Stackless36\Scripts>python pywin32_postinstall.py -install
  4. python C:\code\Python\speech\speak.py

Where speak.py consists of this text:

import win32com.client

speaker = win32com.client.Dispatch("SAPI.SpVoice")
speaker.Speak("It works, bitches.")

Working fine on Python 3.6.4 Stackless 3.1b3 060516 (v3.6.4-slp:9557b2e530, Dec 21 2017, 15:23:10) [MSC v.1900 64 bit (AMD64)] on win32. Vanilla CPython hangs out here:
