python xlwings包错误：OSError:[WinError 2147467259]未指定错误

Question

我正在尝试使用xlwings包将Python数据帧写入.xlsm文件。我的代码有时工作正常，但有时会失败并抛出：

OSError: [WinError -2147467259] Unspecified error

示例代码：

import xlwings as xw
import pandas as pd
import numpy as np
app = xw.App(visible=False)
filename="test.xlsm"
book = xw.Book(filename)
sht = book.sheets("ASSET")
#asset_df ,asset_spec_df are the  data-frame (i get this data-frame value from another function)
sht.range('B9').options(index=False, header=False).value = asset_df
sht=book.sheets("ASSETSPEC")
sht.range('B9').options(index=False, header=False).value = asset_spec_df
book.save()
book.close()
app.quit()

此代码有时会正常工作，但有时会抛出以下错误：

错误：

 book = xw.Book(filename) --- error line

Answer 1

如注释中所述，如果一次在多个实例中打开同一本书（aka..xlsm），应用程序将抛出错误

检查您现在尝试运行的应用程序是否已经在后台运行。如果是，请关闭这些活动应用程序并重新运行
