A solution withoutchanging any files locally and bypassthe version control of your package manager (pip) is to define is_list_likelike this:
不更改本地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
right before
就在之前
import pandas_datareader as web
Furthermore this problem will be fixed in pandas_datareader version 0.7.0 release.
此外，此问题将在 pandas_datareader 0.7.0 版中修复。

Because the is_list_likeis moved to pandas.api.types, I change the fred.py file which is highlighted in the picture. I replace from pandas.core.common import is_list_likewith from pandas.api.types import is_list_like, and it works.
因为is_list_like移到了pandas.api.types，所以我更改了图片中突出显示的fred.py 文件。我代替from pandas.core.common import is_list_like用from pandas.api.types import is_list_like，和它的作品。

This is due to the fact that is_list_likehas been moved from pandas.core.commonto pandas.api.typesin Pandas 0.23.0. This issue has been repaired hereand will be a part of the Pandas Datareader 0.7.0 release. For now, I would recommend using the dev version of Datareader. Instructions for installing can be found in the documentation.
这是由于这样的事实is_list_like已经从移动pandas.core.common到pandas.api.types在大熊猫0.23.0。此问题已在此处修复，并将成为 Pandas Datareader 0.7.0 版本的一部分。目前，我建议使用 Datareader 的开发版本。安装说明可以在文档中找到。
