錯誤提示：

用pandas read_excel()方法讀取xls或xlsx文件時，提示：ImportError: Missing optional dependency ‘xlrd’. Install xlrd >= 1.0.0 for Excel support Use pip or conda to install xlrd.

import numpy as np
import pandas as pd

df = pd.read_excel('pd-test.xls')
print('df=\n',df)

命令行運行py文件提示：

jupyter中運行提示：

 

錯誤原因：

1、提示沒有安裝xlrd模塊，pip方式安裝pandas時不會將xlrd作為依賴自動安裝，需要手動安裝xlrd模塊

 

解決方法：

1、pip手動安裝xlrd模塊。

pip install xlrd  -i https://pypi.tuna.tsinghua.edu.cn/simple
