大多数情况下(在jupyter不在/local/bin的情况下)使用，

which jupyter

示例输出

~/miniconda3/bin/jupyter

要查看jupyter的路径，请使用sudo显式地使用该路径

sudo ~/miniconda3/bin/jupyter 

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

在MacOs上，这对我来说很管用:

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

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
