我正在尝试将我的数据帧从云函数写入 gcs 存储桶，我可以编写 csv 但我无法从云函数写入 excelfile。这是我的代码：

要求.txt

# Function dependencies, for example:
# package>=version
google-cloud-storage==1.30.0
gcsfs==0.6.2
pandas==1.1.0
pandas-gbq==0.15.0
openpyxl==3.0.5
XlsxWriter==1.3.7

主文件

import xlsxwriter
import openpyxl
import numpy as np
import pandas as pd
from pandas.io import gbq
from google.cloud import storage

# Defining Output Folder path.
output_folder = "gs://samples/results/output/"

def testing(request):
  # initialize list of lists
  data = [['tom', 10], ['nick', 15], ['juli', 14]]
  
  # Create the pandas DataFrame
  df = pd.DataFrame(data, columns = ['Name', 'Age'])
  df.to_csv(output_folder + "test_csv.csv", index=False) #able to write csv
  df.to_excel(output_folder + "test_excel.xlsx", index=False) #Error
  return None

Error: FileNotFoundError: [Errno 2] No such file or directory

完全错误：
