因为我开始使用 ubuntu 20.04 LTE，所以我想安装 jupyter notebook 及其控制台。我安装了点子：

sudo apt install python3-pip

因此，我安装了：

pip3 install jupyter

pip3 install notebook

我无法执行任何这些命令来让笔记本或控制台运行。

我发现在我的路径~/.local/bin/中存储了所有这些 python 脚本。从那里我可以运行笔记本和控制台。但是控制台无法执行。它总是抱怨有一些模块丢失或不在路径中。

pip3 也存储在此路径中。我的意思是不应该是这样的/usr/lib/python3/dist-packages/...。我不知道我第一次使用 ubuntu 时是怎么搞砸的。

很抱歉我的描述不清楚，因为 3 小时我试图解决这个问题，但我不再记得每一步了。有人可以帮忙吗？谢谢。
