Searching pyWin32 for Python 3.5.2 version

Question

I'm trying to install the pyWin32 on windows 7, 64 bit and python version 3.5.2. I can't find the pyWin32. I download and install the pyWin32 files from http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyhook and getting error as below:

Exception:
Traceback (most recent call last):
File "C:\Users\nisarahmed.h\AppData\Local\Programs\Python\Python35-32\Lib\shutil.py", 
line 381, in _rmtree_unsafe os.unlink(fullname)

'C:\\Users\\NISARA~1.H\\AppData\\Local\\Temp\\pip-ditl64b5-unpack\\pypiwin32-219-cp35-none-win32.whl'

During handling of the above exception, another exception occurred:

Thanks in advance

Answer 1

I found the answer from Stackoverflow. pip install pywin32 didn't work for me but pip install pypiwin32 did.

Answer 2

I had the same issue. I circumvented the problem by calling the required functions directly, for example:

from ctypes import *

FILE_LIST_DIRECTORY = 0x1
FILE_SHARE_DELETE = 0x00000004
FILE_SHARE_READ = 0x00000001
FILE_SHARE_WRITE = 0x00000002
FILE_FLAG_BACKUP_SEMANTICS = 0x02000000

OPEN_EXISTING = 0x3

handle = windll.kernel32.CreateFileW(
     path,
     FILE_LIST_DIRECTORY,
     FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE,
     None,
     OPEN_EXISTING,
     FILE_FLAG_BACKUP_SEMANTICS,
     None
)

instead of:

import win32file
import win32con
hDir = win32file.CreateFile (
    path_to_watch,
    FILE_LIST_DIRECTORY,
    win32con.FILE_SHARE_READ | win32con.FILE_SHARE_WRITE | win32con.FILE_SHARE_DELETE,
    None,
    win32con.OPEN_EXISTING,
    win32con.FILE_FLAG_BACKUP_SEMANTICS,
    None
 )

I wanted to watch changes in a directory. Tim Golden has examples to use the PyWin32 API for this exact purpose, but I failed to install the package.

Since I only needed two functions I ended up referencing them directly from ctypes.windll.kernel32. This might not be feasible for more complex projects. The Windows Developer Center documents the required functions quite well, so it's easy to find out required flags.

Note that you might have to differentiate unicode and ansi names, e.g. CreateFileW (Unicode) and CreateFileA (ANSI), when looking for the function. This caused some confusion for me, as I was searching for CreateFile rather than CreateFileW.
