我有一个在 Windows Server 2008 上运行的 Python 脚本。它打开一个电子表格并向电子表格添加一个过滤器行，关闭它，然后将其压缩。主电子表格是使用 xlwt 创建的。我只使用 Pywin32，因为用户想要添加一个过滤器行。
当手动执行此操作（即直接通过 Windows 资源管理器或命令行）时，它可以工作。但是，当通过 Task Schduler 手动触发脚本或让它在所需时间触发时，它不起作用。
“运行身份”用户是管理员。我已检查以确保它以最高权限运行。
我通过将输出传送到日志文件来捕获错误消息。回溯显示：
File "C:\www\..\main\management\commands\excel_writer.py", line 183, in add_filter_control
xl.Workbooks.Open(file_path)
File "<COMObject <unknown>>", line 8, in Open
pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, u'Microsoft Office Excel', u'Die Open-Methode des Workbooks-Objektes konnte nicht ausgef\xfchrt werden.', u'C:\\Program Files\\Microsoft Office\\OFFICE11\\1031\\xlmain11.chm', 0, -2146827284), None)
好的......这是德语，但它基本上说“无法执行工作簿打开方法”。
但是，我不知道为什么。有人对如何找出原因有任何提示吗？
干杯

以下是一些代码和设置：
电子表格创建代码
...
w = xlwt.Workbook('UTF-8')

add_filter_control(filepath) << This is where the filter code is called.
ziparchive(filename, archive)

if cellref is not None:
xl.ActiveWorkbook.Worksheets(sheetname).Range(cellref).AutoFilter(1)
xl.ActiveWorkbook.Close(SaveChanges=1) # 1 is True, 0 is False
xl.quit()
