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

如果jupyter运行此命令:

~/.local/bin/jupyter-notebook

只需在终端中运行此命令

 export PATH=~/.local/bin:$PATH

我都试过了，

pip install jupyter

and

pip3 install jupyter

但最后还是用

sudo -H pip install jupyter

以另一个用户-H执行命令

-H (HOME)选项要求安全策略将HOME环境变量设置为密码数据库指定的目标用户(默认为root)的主目录。根据策略的不同，这可能是默认行为。

为了能够从终端运行jupyter notebook，您需要确保~/。Local /bin在您的路径中。

通过执行export PATH=$PATH:~/来实现。当前会话的本地/bin，或者将该行添加到~/的末尾。Bashrc使您的更改在以后的会话中持续(例如使用nano ~/. Bashrc)。如果您编辑~/。Bashrc，您将需要登出并重新登录，以查看您的更改生效。

用conda重新安装jupyter:

conda install jupyter

在MacOs上，这对我来说很管用:

/Users/`userName`/opt/anaconda3/bin/jupyter_mac.command
