“OSError：[Errno 9]错误的文件描述符”与 pandas.to_excel() 函数

Question

我正在使用pandas中的函数

.to_excel()

，

import pandas as pd

df = pd.DataFrame([[1, 2], [3, 4]])
with pd.ExcelWriter('output.xlsx') as writer:
    df.to_excel(writer, sheet_name="MySheet")

这会导致错误

OSError: [Errno 9] Bad file descriptor

Excel文件已经存在，但在其他地方打不开。

我正在使用python 3.10.11，pandas 2.2.3，openpyxl 3.1.5

追溯：

    with pd.ExcelWriter('output.xlsx') as writer:

  File ~\AppData\Local\Programs\Python\Python310\lib\site-packages\pandas\io\excel\_base.py:1353 in __exit__
    self.close()

  File ~\AppData\Local\Programs\Python\Python310\lib\site-packages\pandas\io\excel\_base.py:1357 in close
    self._save()

  File ~\AppData\Local\Programs\Python\Python310\lib\site-packages\pandas\io\excel\_openpyxl.py:110 in _save
    self.book.save(self._handles.handle)

  File ~\AppData\Local\Programs\Python\Python310\lib\site-packages\openpyxl\workbook\workbook.py:386 in save
    save_workbook(self, filename)

  File ~\AppData\Local\Programs\Python\Python310\lib\site-packages\openpyxl\writer\excel.py:294 in save_workbook
    writer.save()

  File ~\AppData\Local\Programs\Python\Python310\lib\site-packages\openpyxl\writer\excel.py:275 in save
    self.write_data()

  File ~\AppData\Local\Programs\Python\Python310\lib\site-packages\openpyxl\writer\excel.py:60 in write_data
    archive.writestr(ARC_APP, tostring(props.to_tree()))

  File ~\AppData\Local\Programs\Python\Python310\lib\zipfile.py:1816 in writestr
    with self.open(zinfo, mode='w') as dest:

  File ~\AppData\Local\Programs\Python\Python310\lib\zipfile.py:1180 in close
    self._fileobj.seek(self._zinfo.header_offset)

OSError: [Errno 9] Bad file descriptor

Answer 1

正如我在评论中提到的，问题出在文件权限或文件被锁定/使用时。

尝试这样。

以

w

写入模式运行。

with pd.ExcelWriter('output.xlsx', mode='w', if_sheet_exists='replace') as writer:
    df.to_excel(writer, sheet_name="MySheet", index=False)

或者使用不同的引擎

df.to_excel('output.xlsx', sheet_name="MySheet", engine='xlsxwriter', index=False)
