Import pyfinance 后报错

首先在anaconda里面安装完成pyfinance后，在spyder里面 import pyfinance，提示报错如下：

Traceback (most recent call last):

File "D:\MustHaveSoft\Anaconda\lib\site-packages\pyfinance\utils.py", line 78, in
from pandas.tseries.frequencies import FreqGroup, get_freq_code

ImportError: cannot import name 'FreqGroup' from 'pandas.tseries.frequencies' (D:\MustHaveSoft\Anaconda\lib\site-packages\pandas\tseries\frequencies.py)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

File "", line 1, in

百度了一圈楞是没找到和我有相似问题的人，求解~

如果你安装好了，但是在spyder里又没有，表示spyder里面的python解释器并没有安装成功，安装成功的是你电脑其他的Python版本
