python - import pandas_datareader 给出 ImportError : cannot import name 'is_list_like'

Question

我在虚拟环境中工作。我可以在没有任何错误的情况下导入和使用 Pandas ，但是当我尝试 import pandas_datareader

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import datetime as dt
from matplotlib import style
import pandas_datareader as web

它给出了以下错误-

Traceback (most recent call last):
  File "stock.py", line 6, in <module>
    import pandas_datareader as web
  File "/home/xxxxx/django-apps/env/lib/python3.5/site-packages/pandas_datareader/__init__.py", line 2, in <module>
    from .data import (DataReader, Options, get_components_yahoo,

ImportError: cannot import name 'is_list_like'

Answer 1

不在本地更改任何文件并绕过包管理器 (pip) 的版本控制的解决方案是像这样定义 is_list_like:

import pandas as pd
pd.core.common.is_list_like = pd.api.types.is_list_like

就在之前

import pandas_datareader as web

此外，此问题将在 pandas_datareader 0.7.0 版本中修复。
