以下是我在Linux mint 19上所做的:

我安装jupyter与:

pip install jupyter

和命令:

jupyter notebook

没有工作，所以:

sudo apt install jupyter-notebook

我解决了这个问题，jupyter笔记本工作了。

使用Ctrl+Alt+T打开终端窗口。 执行gedit ~/.profile命令。 加线。导出路径= $路径:/。local / bin / jupyter-notebook。到底部保存。 注销后重新登录。

希望这能起作用。

在Mac OS上，您需要导出~/。在$PATH变量中使用local/bin。

# Edit the bash profile:
$ vim ~/.bash_profile

# Add this line inside ~/.bash_profile:
export PATH=$PATH:~/.local/bin

# Update the source:
$ source ~/.bash_profile

# Open Jupyter:
$ jupyter notebook

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

在Mac Os High Sierra上，我安装了jupyter

python3 -m pip install jupyter    

然后，二进制文件被安装在:

/Library/Frameworks/Python.framework/Versions/3.6/bin/jupyter-notebook

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
