1、簡述

今天閑得蛋疼在cmd下使用pip install jupyter安裝了jupyter notebook，想研究研究，可惜用了一會(huì)兒暫時(shí)覺得對(duì)我無用，所以想卸載了它，于是輸入命令pip unstall jupyter，哪知查詢后只是卸載了jupyter，其依賴關(guān)系庫依然存在。
百度一番沒有結(jié)果，然后使用google輸入how to uninstall jupyter就發(fā)現(xiàn)了pip-autoremove這個(gè)卸載工具：how-to-uninstall-jupyter

• 輸入pip install pip-autoremove安裝該工具
• 輸入pip-autoremove jupyter -y卸載jupyter
