jupyter-lab - 初始化jupyter lab时配置错误

Question

以下是初始化Jupyter lab时报错的信息。错误似乎并不严重，但我无法打开网页。我如何解决它？令我惊讶的是，Jupyter notebook 运行良好。

[~] jupyter lab

[I ... ServerApp] jupyterlab | extension wassuccessfully linked. [W 2021-08-28 11:32:26.627 NotebookApp] 'browser'has moved from NotebookApp to ServerApp. This config will be passed toServerApp. Be sure to update your config before our next release.

[W ... NotebookApp] 'notebook_dir' has moved fromNotebookApp to ServerApp. This config will be passed to ServerApp. Besure to update your config before our next release.

[C ... NotebookApp] Bad config encountered duringinitialization: Trait, server_extensions, not found.

感谢您的帮助。所有错误都消失了，除了最后一条信息:初始化期间遇到错误配置:特征、server_extensions、未找到。

配置目录下有一个json文件，里面写着

{
  "NotebookApp": {
    "server_extensions": [
      "jupyter_nbextensions_configurator"
    ],
    "nbserver_extensions": {
      "jupyterlab": true
    }
  }
}

最后，我在删除配置目录后重新安装了 jupyterlab。它现在才有效。我该结束这个话题了。
