我正在尝试在 Python 3.7 中使用 Jupyter 笔记本安装索引器。

pip install indexer

我收到以下错误。

Collecting indexer

    Complete output from command python setup.py egg_info:

        except OSError, ex:

    ----------------------------------------
Note: you may need to restart the kernel to use updated packages.
Command "python setup.py egg_info" failed with error code 1 in C:\Users\manorama\AppData\Local\Temp\pip-install-vs0071ok\indexer\

我尝试了各种解决方案，例如

pip install --upgrade setuptools
pip install ez_setup

但没有任何效果。

如何安装索引器包？
