ImportError:无法导入名称'PandasError'

Question

我是Python 3x的新手,在mac上运行.

目前使用带有finance的python的sentdex教程,尝试运行以下脚本:

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())

但是,这会返回以下错误消息:

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\__init__.py", line 3, in <module>
    from .data import (get_components_yahoo, get_data_famafrench, get_data_google, get_data_yahoo, get_data_enigma,  # noqa

    from pandas_datareader.google.daily import GoogleDailyReader

    from pandas_datareader.base import _DailyBaseReader
  File "C:\Python36\lib\site-packages\pandas_datareader\base.py", line 13, in <module>
    from pandas_datareader._utils import (RemoteDataError, SymbolWarning,
  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'

我想也许panda-datareader本身有问题,我已经确保它已升级到最新版本(pandas-datareader 0.3.0.post0)

是否有我可以安装的旧版本？我一直在使用pip3通过mac终端安装.

非常感谢您的帮助!

Answer 1

我想你昨天发布了pandas v.0.20.1.pandas-datareader仍然与这个版本不兼容,目前你应该留在pandas 0.19.2:

pip install -U pandas==0.19.2

Answer 2

pandas_datareader(0.5.0)的最新版本负责此导入错误.你可以安装它pip:

sudo pip install -U pandas_datareader
