如何修复“ ImportError：无法导入名称'StringIO'”

Question

python版本是3.6.6，而pandas_datareader版本是0.7.0

当我导入pandas_datareader时，发生如下错误。

C:\PycharmProjects\Demo\venv\Scripts\python.exe C:/PycharmProjects/Demo/stock.py
Traceback (most recent call last):
  File "C:/PycharmProjects/Demo/stock.py", line 3, in <module>
    import pandas_datareader as wb
  File "C:\PycharmProjects\Demo\venv\lib\site-packages\pandas_datareader\__init__.py", line 2, in <module>
    from .data import (DataReader, Options, get_components_yahoo,
  File "C:\PycharmProjects\Demo\venv\lib\site-packages\pandas_datareader\data.py", line 7, in <module>
    from pandas_datareader.av.forex import AVForexReader
  File "C:\PycharmProjects\Demo\venv\lib\site-packages\pandas_datareader\av\__init__.py", line 3, in <module>
    from pandas_datareader.base import _BaseReader
  File "C:\PycharmProjects\Demo\venv\lib\site-packages\pandas_datareader\base.py", line 11, in <module>
    from pandas.compat import StringIO, bytes_to_str
ImportError: cannot import name 'StringIO'

有人可以帮我吗？

Answer 1

问题是pandas 0.25.0 已经删除了pandas.compat。所以回到 0.24.2

pip install "pandas<0.25.0"

或者

pipenv install "pandas<0.25.0"

我在Python3.6和Python3.7中遇到了同样的问题

降级了，在Python2.7上也能正常运行 另外，看到上面有评论说Python3.5也能运行。
