1、在终端中输入‘sudo pip3 install jupyter’, 出现黄色的‘warring',如下：

The directory '/home/stone/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag. The directory '/home/stone/.cache/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory.

解决方法：

在sudo 后面添加-H
sudo -H pip3 install jupyter
