jupyter notebook 无法在 Chrome OS 上启动

Question

我刚刚用 pip 在我的 Chromebox (Chrome OS) 上安装了 jupyter notebook，我收到以下输出错误：

Traceback (most recent call last):
  File "/usr/local/bin/jupyter-notebook", line 10, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.7/dist-packages/jupyter_core/application.py", line 264, in launch_instance
    return super(JupyterApp, cls).launch_instance(argv=argv, **kwargs)
  File "/usr/local/lib/python3.7/dist-packages/traitlets/config/application.py", line 845, in launch_instance
    app.initialize(argv)
  File "/usr/local/lib/python3.7/dist-packages/traitlets/config/application.py", line 88, in inner
    return method(app, *args, **kwargs)
  File "/usr/local/lib/python3.7/dist-packages/notebook/notebookapp.py", line 2141, in initialize
    self._init_asyncio_patch()
  File "/usr/local/lib/python3.7/dist-packages/notebook/notebookapp.py", line 2117, in _init_asyncio_patch
    nest_asyncio.apply()
  File "/usr/local/lib/python3.7/dist-packages/nest_asyncio.py", line 14, in apply
    raise ValueError('Can\'t patch loop of type %s' % type(loop))
ValueError: Can't patch loop of type <class 'NoneType'>

这是 jupyter --version 的输出：

Selected Jupyter core packages...
IPython          : 7.30.0
ipykernel        : 6.6.0
ipywidgets       : 7.6.5

jupyter_core     : 4.9.1
jupyter_server   : 1.12.1
jupyterlab       : 3.2.4
nbclient         : 0.5.9
nbconvert        : 6.3.0

notebook         : 6.4.6
qtconsole        : 5.2.1
traitlets        : 5.1.1

有什么提示吗？谢谢

这可能是 nest-asyncio=1.5.2 (issue) 的问题。您可以运行以下命令卸载 nest-asyncio=1.5.2 的现有版本并升级到 1.5.3:

pip uninstall nest-asyncio
pip install nest-asyncio==1.5.3
