ImportError: cannot import name 'PandasError'

问题

I am very new to Python 3x, running on a mac.

Currently using a sentdex tutorial for python with finance, tried running the following script:

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(2000,1,1)
end = dt.datetime(2016,12,31)

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

However this returns the following error message:

Traceback (most recent call last):
  File "F:\Downloads\Python Work\try figuring thigns out\finance\try.py", line 1, in <module>
    import pandas_datareader.data as web

  File "C:\Python36\lib\site-packages\pandas_datareader\_utils.py", line 5, in <module>
    from pandas.core.common import PandasError
ImportError: cannot import name 'PandasError'

I think maybe there's something wrong with panda-datareader itself, which I've ensured has been upgraded to most recent version (pandas-datareader 0.3.0.post0)

Is there an older version I can install instead? I've been using pip3 to install via mac terminal.

Thanks very much for any help!

I think you installed pandas v. 0.20.1 released yesterday. pandas-datareader is still not compatible with this version, for the moment you should stay on pandas 0.19.2:
