Python错误集锦:pandas读取excel提示ImportError: Missing optional dependency ‘xlrd’.

原文链接:http://www.juzicode.com/archives/3125

错误提示:

用pandas read_excel()方法读取xls或xlsx文件时,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)

命令行运行py文件提示:

Traceback (most recent call last):
  File "pd-test.py", line 4, in <module>
    df = pd.read_excel('pd-test.xls')
  File "D:\Python\Python38\lib\site-packages\pandas\util\_decorators.py", line 296, in wrapper
    return func(*args, **kwargs)

    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.

jupyter中运行提示:

错误原因:

1、提示没有安装xlrd模块,pip方式安装pandas时不会将xlrd作为依赖自动安装,需要手动安装xlrd模块

解决方法:

1、pip手动安装xlrd模块。

pip install xlrd  -i https://pypi.tuna.tsinghua.edu.cn/simple
import numpy as np
import pandas as pd

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