无法在 Windows 10 上导入 pywinauto

Question

我使用pip install pywinauto 安装了pywinauto。

操作系统：Windows 10

Python：3.6.2

当我运行 python 并尝试导入 pywinauto 时，我收到错误：

FileNotFoundError: [WinError 2] The system cannot find the file specified: 'UIAutomationCore.dll'

任何想法如何解决这个问题？

Answer 1

我今天遇到了同样的问题，并由pip install comtypes==1.1.7 修复。 它是由 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，现在运行良好。

Answer 2

它应该在 comtypes==1.1.9 中修复。请检查。

问题是在comtypes==1.1.8 中引入的。我的错。

Answer 3

尝试使用不同版本的 python（例如 3.7.5 或 3.8）：

https://github.com/pywinauto/pywinauto/issues/887

“在 Python 3.7.6 和 3.8.1 中存在同样的问题。在 3.7.5 或 3.8 中不会出现问题。 我认为这将在 3.8.2 中修复（但还不确定）”

Answer 4

试试这个，对我来说效果很好

1. 从https://github.com/mhammond/pywin32/releases安装pywin32
2. pip install -U comtypes
3. pip install six
4. pip install Pillow
5. cd c:\windows\syswow64\
6. regsvr32 UIAutomationCore.dll
7. python
8. import pywinauto #问题应该解决了

我有 Win10 和 python 3.9.....我不喜欢 Win10 另一件事可能是您的 numpy 库，将其卸载并重新安装。 pip 卸载 numpy 点安装 numpy
