在 pyWin32 中搜索 Python 3.5.2 版本

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 pyWin32 文件并收到如下错误：

Exception:

During handling of the above exception, another exception occurred:

我遇到了同样的问题。我通过直接调用所需函数来规避问题，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
 )

我想查看目录中的更改。 Tim Golden examples 将 PyWin32 API 用于此确切目的，但我未能安装该软件包。

因为我只需要两个函数，所以我最终直接从 ctypes.windll.kernel32 引用了它们。对于更复杂的项目，这可能不可行。 Windows Developer Center 对所需的功能进行了详细的记录 well，因此很容易找到所需的标志。

请注意，您可能需要区分 unicode 和 ansi 名称，例如CreateFileW (Unicode) 和 CreateFileA (ANSI)，寻找函数时。这让我有些困惑，因为我正在搜索 CreateFile 而不是 CreateFileW.

我从Whosebug找到了答案。 pip install pywin32 对我没用，但 pip install pypiwin32 对我有用。
