1、简述
今天闲得蛋疼在cmd下使用pip install jupyter安装了jupyter notebook，想研究研究，可惜用了一会儿暂时觉得对我无用，所以想卸载了它，于是输入命令pip unstall jupyter，哪知查询后只是卸载了jupyter，其依赖关系库依然存在。
百度一番没有结果，然后使用google输入how to uninstall jupyter就发现了pip-autoremove这个卸载工具：how-to-uninstall-jupyter
- 输入
pip install pip-autoremove安装该工具 - 输入
pip-autoremove jupyter -y卸载jupyter
