任何人寻找运行的jupyter作为sudo，当jupyter安装virtualenv(没有sudo) -这为我工作:

首先验证这是一个PATH问题:

检查jupyter返回的路径是否被sudo用户覆盖:

sudo env | grep ^PATH

(相对于当前用户:env | grep ^PATH)

如果它没有覆盖-添加一个软链接从它覆盖的路径之一。为例:

sudo ln -s /home/user/venv/bin/jupyter /usr/local/bin

现在你应该能够运行:

sudo jupyter notebook

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

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

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

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
