在学习Python中pandas的过程中，打算将爬虫取到的数据保存到Excel文件中，使用

df=pandas.DataFrame(c)
#print(df)
df.to_excel('house.xlsx',sheet_name='sheet1')

　　总是报错 Module Not Found Error: No module named 'openpyxl'
发现是有个库没有导入

问题：

Traceback (most recent call last):
  File "E:/testPython/machine_learn/expmle_test1/Shells_Reptile.py", line 28, in <module>
    df.to_excel('house.xlsx',sheet_name='sheet1')
  File "E:\testPython\venv\lib\site-packages\pandas\core\generic.py", line 2256, in to_excel
    engine=engine,

    from openpyxl.workbook import Workbook
ModuleNotFoundError: No module named 'openpyxl'

解决办法：

使用:pip list查看是否有：openpyxl这个包；

没有导入：pip install openpyxl

import openpyxl

import requests
import pandas
import openpyxl

即可
