无法在Windows 10上导入pywinauto

约翰·安德森

我安装pywinauto使用pip install pywinauto。

作业系统：Windows 10

的Python：3.6.2

当我运行python并尝试导入时pywinauto，出现错误：

Python 3.6.2 (v3.6.2:5fd33b5, Jul  8 2017, 04:57:36) [MSC v.1900 64 bit (AMD64)] on win32

    tlib_mtime = os.stat(self.filename).st_mtime
FileNotFoundError: [WinError 2] The system cannot find the file specified: 'UIAutomationCore.dll'

任何想法如何解决这一问题？

我今天有相同的问题，并通过进行了解决pip install comtypes==1.1.7。这是由comtypes库引起的，该库在12月26日发布了新版本1.1.8。降级到以前的版本，现在可以正常运行。
