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

我通过pip安装了pandas_datareader，但一切都成功了。

当我尝试运行一个简单的代码时，我得到了以下错误：

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

Traceback (most recent call last):

我有Python 2.7版本和Windows 7 64位系统。

安装过程是否有问题？
