用conda重新安装jupyter:

conda install jupyter

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。

更新的Jupyter版本默认不附带笔记本组件。

根据你的包管理器，你可以通过以下方式安装笔记本组件:

pip install notebook

or

poetry add notebook

Try

Python -m notebook

或者，如果您使用pip3安装笔记本:

Python3 -m笔记本

在Mac OS Catalina和Python3.7上

我用下面的命令从源代码编译了python3.7

./configure --prefix=/opt/python3.7.4 --with-ssl
make
make install

pip3.7安装jupyter后，我发现可执行文件在/opt/python3.7.4/bin下

在Python3编译后缺少sqlite3以获得更多关于python3.7和ubuntu14.04下pip的详细信息

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
