Question

尝试保存带注释的Excel工作簿时出现问题。在Excel文件中没有任何注释，我的脚本没有问题。我只是使用：

wb_archive = load_workbook(archive_file)

但是，如果我要保存的文件带有注释，则该文件不起作用，并且显示以下消息：

AttributeError：'NoneType'对象没有属性'read'

因此，我使用以下方法打开文件：

wb_archive = load_workbook(archive_file, keep_vba=True)

第一次运行是可以的，但是第二次总是失败，并显示以下错误：

KeyError：“存档中没有名为'xl / sharedStrings.xml'的项目”

我在代码的某处错了吗？
