ImportError：无法导入名称'StringIO'

Question

我正在尝试通过代码从雅虎公司的股票中获取数据。 但是我在pandas_datareader.data上收到ImportError，说 ImportError：无法导入名称“ StringIO” 请帮忙 我对此很陌生...已经花费了4个小时，但无法解决。

我什至尝试过

import io 
from io import StringIO

仍然出现相同的错误.. !!

import datetime as dt 
import matplotlib.pyplot as plt 
from matplotlib import style 
import pandas as pd 
import pandas_datareader.data as web 



style.use('ggplot')
start = dt.datetime(2018,1,1)
end = dt.datetime(2018,12,31)

df = web.datareader('TSLA','yahoo',start,end)
print(df.head(5))

错误：-
