Question

我正在尝试在Windows 7,64位和python版本3.5.2上安装pyWin32。我找不到pyWin32。我从http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyhook下载并安装了pyWin32个文件，并收到如下错误：

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)

During handling of the above exception, another exception occurred:

Answer 1

我有同样的问题。我通过直接调用所需的函数来规避问题，例如：

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
)

而不是：

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
 )

我想观看目录中的更改。 Tim Golden有examples使用PyWin32 API用于此目的，但我无法安装该软件包。

由于我只需要两个函数，所以我最终直接从ctypes.windll.kernel32引用它们。对于更复杂的项目，这可能不可行。 Windows开发人员中心非常详细地记录了所需的功能well，因此很容易找到所需的标记。

请注意，您可能必须区分unicode和ansi名称，例如在查找函数时，CreateFileW（Unicode）和CreateFileA（ANSI）。这对我造成了一些困惑，因为我正在搜索CreateFile而不是CreateFileW。

Answer 2

我从Stackoverflow找到答案。 pip install pywin32 pip install pypiwin32对我无效，但.git/确实如此。

搜索pyWin32 for Python 3.5.2版本
