pandas_datareader ImportError：無法導入名稱string_types

Question

import pandas_datareader as pdr 
pdr.get_data_yahoo('AAPL') 

我通過pip安裝了pandas_datareader，並且它全部成功。

當我嘗試運行一個簡單的代碼，我得到以下錯誤：

"C:\Users\<username>\Anaconda2\python.exe" 
"C:/Users/<username>/PycharmProjects/untitled2/Yahoo.py"

我的Python 2.7版本ADN的Windows 7 64位系統。

安裝過程是否有問題？

conda版本問題。需要升級conda版本
