安装 jupyterlab。

如果你得到这个错误:

ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.

We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.

requests 2.25.1 requires idna<3,>=2.5, but you'll have idna 3.1 which is incompatible.

用这个:

pip3 install jupyterlab --use-feature=2020-resolver

你没有退出并重新登录吗?它应该在您执行的路径上。 如果不是，pip在.local中安装可执行文件，所以在终端中:

 ~/.local/bin/jupyter-notebook

应该开始写笔记本

如果你使用'pip'而不是'pip3'为Python 2安装Jupyter notebook，它可能会运行:

ipython notebook

大多数情况下(在jupyter不在/local/bin的情况下)使用，

which jupyter

示例输出

~/miniconda3/bin/jupyter

要查看jupyter的路径，请使用sudo显式地使用该路径

sudo ~/miniconda3/bin/jupyter 

尝试“pip3 install jupyter”，而不是pip。这对我很管用。
