对我来说，在激活虚拟环境之前，它不起作用。

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

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

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

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
