openpyxl库更新后无法导入save_virtual_workbook的问题咨询

Hey there, sorry to hear you're stuck with this issue after updating openpyxl—sudden breaks like this right after an update are so frustrating!

The problem here is that the save_virtual_workbook function got removed in newer versions of openpyxl. It used to live in the openpyxl.writer.excel module, but the development team decided to deprecate it in favor of a more standard approach using in-memory byte streams.

Luckily, there's a straightforward replacement that does exactly the same thing. Here's how you can adjust your code:

• If your old code looked like this:

  from openpyxl.writer.excel import save_virtual_workbook
  # 假设wb是你的工作簿对象
  workbook_bytes = save_virtual_workbook(wb)
  

• You can swap it out with this using io.BytesIO:

  from io import BytesIO
  # 假设wb是你的工作簿对象
  output_stream = BytesIO()
  wb.save(output_stream)
  # 记得把流指针移回开头，这样后续读取的时候能拿到完整内容
  output_stream.seek(0)
  # 如果需要字节数据，就用getvalue()
  workbook_bytes = output_stream.getvalue()
  

This approach is the official recommended alternative now, and it works just as well as the old function did for saving your workbook to an in-memory byte stream instead of a file.
