我想从终点站启动Jupyterlab

我在MacOS 10.14上。 我用自制软件安装了Python 我尝试使用
brew安装Jupyter lab
安装Jupyter lab,但收到以下错误消息:

Error: No available formula with the name "jupyterlab" 
==> Searching for a previously deleted formula (in the last month)...
Warning: homebrew/core is shallow clone. To get complete history run:
  git -C "$(brew --repo homebrew/core)" fetch --unshallow

Error: No previously deleted formula found.
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
==> Searching taps on GitHub...
Error: No formulae found in taps.
我试着用
pip3
命令
pip3 install jupyterlab
安装它。成功了。但是,当我尝试使用命令
jupyter lab
启动它时,我收到以下错误消息: 执行Jupyter命令“lab”时出错:

[Errno 2] No such file or directory
当我运行命令
brew list
时,
jupyterlab
不在列表中


我怀疑问题在于
pip3
homebrew
没有以相同的方式管理路径,而问题就在那里。我该怎么办呢?

好的,我刚刚用
brew
重新安装了jupyter(
brew重新安装jupyter
),用
pip3重新安装了jupyterlab安装了jupyter lab
,它成功了
