All*_*uza 4 python dataframe stock pandas pandas-datareader
我正在尝试使用 python 中的 pandas datareader 使用 data_source 作为 Yahoo 来获取一家公司（在本例中为 APPLE）的历史价格数据。
直到几天前（2021 年 7 月），这种方法还很有效。我不确定雅虎是否再次停止了他们的 API 或者只是我一个人这样做。
import pandas_datareader as wb
data = wb.DataReader('AAPL', data_source='yahoo', start='2019-9-1')
print(data)
这是我得到的错误：

我有同样的错误。
我将 pandas-datareader 从 0.9.0 升级到 0.10.0。我还将 pandas 从 1.1.1 升级到了 1.3.0。
然后错误就消失了。我不知道哪一个真正解决了这个问题。
一种可能的升级方法是键入：pip install --upgrade pandas-datareader。
