centos - 在 jupyterHub 上为 jupyterLab 获取 404

Question

所以我试图在生产模式(Centos)下使用 JupyterLab 设置 JupyterHub 服务。为简单起见，我选择了系统用户身份验证 (PAM)。所以现在我有几个用户能够运行单个服务器。问题是我需要设置一个 JupyterLab 才能正常工作。
我做了一切(可能还有更多)jupyterhub 文档告诉我要做的事情:

在系统范围内启用 jupyterlab 扩展 ( jupyter serverextension enable --py jupyterlab --sys-prefix )

添加了所需的配置选项 ( c.Spawner.cmd = ["jupyter-labhub"] )

其他一些没用的东西
但是 /lab url 仍然返回 404 错误。
相关控制台输出:

我没有任何想法，因此将不胜感激。

Answer 1

所以，我通过 pip3 安装 jupyterlab 包来解决这个问题。
这就是它的样子:

我尝试为具有 /home/jupyterhub/.local/bin/pipenv run jupyter serverextension enable --py jupyterlab --user 的用户启用 jupyterlab
但那返回我异常:

ModuleNotFoundError: No module named 'jupyterlab'I re-checked that my Pipfile.lock includes a jupyterlab extension... and it was!2. I tried to install jupyterlab with the most standart way:

pip3 install jupyterlab它做了一件事!
仍然不确定为什么使用 pipenv 安装的 jupyterlab 没有结果。
