我是Python的新手，openpyxl软件包遇到了一个非常令人困惑的问题。
每次我尝试将工作簿保存到文件时，都会出现错误： TypeError：输入类型，预期字符串或Element的输入值无效
即使对于非常简单直接的代码，我也会遇到相同的错误：
wb = openpyxl.Workbook()
ws = wb.active
ws.title = 'test'
ws['A1'].value = 'test'
ws['A2'].value = 'design'
wb.save("D:\\PyData\\test\\test.xlsx")
此“ text.xlsx”文件将被创建，但已损坏，尽管我可以将其解压缩以查看3个文件，但Microsoft Excel无法打开它。
这是完整的追溯：

我认为我可能错过了一些东西，但确实找不到。我在论坛上搜索，但似乎没有人遇到相同的问题。
任何人都可以给我一些提示吗？
非常感谢
