带有 jupyter 实验室的 Django 扩展 shell_plus

问题描述

我一直在尝试使用 ./manage.py shell_plus --lab 命令，但我不断收到以下错误：

...
  File "/home/user/.local/share/virtualenvs/project-MorsWGAo/lib/python3.8/site-packages/django_extensions/management/commands/shell_plus.py",line 556,in handle
    runner()
  File "/home/user/.local/share/virtualenvs/project-MorsWGAo/lib/python3.8/site-packages/django_extensions/management/commands/shell_plus.py",line 303,in run_jupyterlab
    self.run_notebookapp(app,options)
  File "/home/user/.local/share/virtualenvs/project-MorsWGAo/lib/python3.8/site-packages/django_extensions/management/commands/shell_plus.py",line 237,in run_notebookapp
    app.initialize(notebook_arguments)
  File "/home/user/.local/share/virtualenvs/project-MorsWGAo/lib/python3.8/site-packages/jupyterlab/labapp.py",line 732,in initialize
    super().initialize()
  File "/home/user/.local/share/virtualenvs/project-MorsWGAo/lib/python3.8/site-packages/jupyter_server/extension/application.py",line 403,in initialize
    raise JupyterServerExtensionException(msg)
jupyter_server.extension.application.JupyterServerExtensionException: This extension has no attribute `serverapp`. Try calling `.link_to_serverapp()` before calling `.initialize()`.

我正在使用 pipenv 这可能是我的 Pipfile 的潜在相关部分：

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[scripts]
dev = "./scripts/dev.sh"

[requires]
python_version = "3.8"

[pipenv]
allow_prereleases = true

[packages]
Django = "~=3.0.0"
...
django-extensions = "*"
...
[dev-packages]
Flake8 = "*"
autoflake = "*"
bpython = "*"
epc = "*"
importmagic = "*"
ipdb = "*"
ipython = "*"
pyls-black = "*"
pyls-isort = "*"
coverage = "*"
werkzeug = "*"
jupyterlab = "*"

我真的很感激这方面的任何帮助。提前谢谢。

编辑

简单的解决方法是使用 ./manage.py shell_plus --notebook，然后在浏览器中简单地导航到 /lab 并在 notebooks 部分选择 Django Shell-Plus。
