如何修復“ImportError：無法導入名稱'StringIO'”

Question

python版本是3.6.6，pandas_datareader版本是0.7.0

當我導入pandas_datareader時，會發生如下錯誤。

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'

有人能幫助我嗎？

Answer 1

問題是pandas 0.25.0刪除了pandas.compat。 所以回到0.24.2

pip install "pandas<0.25.0"

要么

pipenv install "pandas<0.25.0"

Answer 2

我遇到了與Python3.6和Python3.7相同的問題

降級，它在Python2.7上工作正常。另外，看到上面的注釋，Python3.5的工作原理。
