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

在终端中执行

export PATH=~/anaconda3/bin:$PATH

为我工作过Ubuntu 16.10, Python3, Anaconda3

更新

在~/中添加路径。Bashrc或~/。Zshrc(如果您正在使用ZSH bash)文件

vi ~/.bashrc

向文件中添加以下行

PATH=~/path/to/anaconda:$PATH

用以下命令关闭文件

esc + : + wq

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

我尝试了所有的方法，最后在运行树莓派4的树莓派操作系统上，这对我来说是有效的

sudo apt install python3-notebook jupyter jupyter-core

唯一对我有用的是将与pip3相关的Python版本导出到PATH:)(经过大量的挣扎) 运行:

which pip3

你应该得到这样的东西(在Mac中):

/Library/Frameworks/Python.framework/Versions/3.6/bin/pip3

现在运行:

export PATH=/Library/Python/3.6/bin:$PATH

如果它对你有用:)就把它添加到你的 Bashrc或ZSHRC

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
