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，可惜用了一會兒暫時覺得對我無用，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，其依賴關系庫依然存在。
百度一番沒有結果，然后使用google輸入how to uninstall jupyter就發現了pip-autoremove這個卸載工具：how-to-uninstall-jupyter

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