用python读取Excel表格时出现的一些问题

import numpy as np
 import pandas as pd
data = pd.DataFrame([])

path='/Users/yingtian/Desktop/读取的文件.xlsx'

f = pd.ExcelFile(path)

此时报错：

Traceback (most recent call last): File “”, line 1, in

f = pd.ExcelFile(path) File “/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/pandas/io/excel/_base.py”,

raise ImportError(msg) from None ImportError: Missing optional dependency ‘xlrd’. Install xlrd >= 1.0.0 for Excel support Use pip or
conda to install xlrd.

解决“ImportError: Missing optional dependency ‘xlrd’. Install xlrd >= 1.0.0 for Excel support Use pip or conda to install xlrd.”的方法：
在终端按装xlrd模块：

pip install xlrd

没有成功。
先执行：

engine=‘openpyxl’

然后再执行：

pip install xlrd

安装成功。

重新在python中执行：

f = pd.ExcelFile(path)

此时报错：

Traceback (most recent call last): File “”, line 1, in

f = pd.ExcelFile(path) File “/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/pandas/io/excel/_base.py”,

raise ValueError( ValueError: Your version of xlrd is 2.0.1. In xlrd >= 2.0, only the xls format is supported. Install openpyxl
instead.

在终端中执行：

pip install openpyxl

Collecting openpyxl

此时

f = pd.ExcelFile(path)

可正常运行。
