这是我的代码

import win32com.client as win32
excel = win32.gencache.EnsureDispatch('Excel.Application')

我正在使用 PyCharm VirtualEnv

我没有找到任何解决方案，有人对此有想法吗？

注意：我是如何尝试使用 win32 访问 excel 工作簿的，以便能够修改它！！..

Answer 1

您必须考虑 运行 来自虚拟环境的代码。

并卸载环境外的任何其他 pywin32 模块。

试一试！

Answer 2

遇到同样的问题并通过关闭所有 运行 Excel 个应用程序来解决它。

Answer 3

我遇到了同样的问题...通过添加这两行解决了我的问题：

workbook.Close(SaveChanges=True)
xl.Quit()

Answer 4

如果 运行 行 excel = win32.gencache.EnsureDispatch('Excel.Application') 在您的实例中不止一次（又名 For 循环），也会出现问题。
