Python pandas.io.data 模块迁移

这段时间用pandas做数据分析，

1

import pandas.io.data as web

 然后得到下面的错误提示

    "The pandas.io.data module is moved to a separate package "

ImportError: The pandas.io.data module is moved to a separate package (pandas-datareader). After installing the pandas-datareader package (https://github.com/pandas-dev/pandas-datareader), you can change the import ``from pandas.io import data, wb`` to ``from pandas_datareader import data, wb``.

　　原来是迁移到了pandas-datareader包，但是 

1

import pandas-datareader.io.data as web

 仍然错误，于是我进Pypi查了一下这个包，原来这个包从0.19.0已经不再支持 pandas.io.data 和 pandas.io.wb，需将pandas.io换成pandas_datareader，即

1

import pandas_datareader.data as web
