无法从 'jupyterlab_server' 导入名称 'WORKSPACE_EXTENSION'

Question

更新到最近的jupyter_server(1.13.1)后，当我进入

jupyter lab

我明白了

Traceback (most recent call last):
  File "/usr/local/bin/jupyter-lab", line 5, in <module>
    from jupyterlab.labapp import main
  File "/usr/local/lib/python3.9/site-packages/jupyterlab/__init__.py", line 7, in <module>
    from .labapp import LabApp
  File "/usr/local/lib/python3.9/site-packages/jupyterlab/labapp.py", line 18, in <module>
    from jupyterlab_server import WORKSPACE_EXTENSION, LabServerApp, slugify
ImportError: cannot import name 'WORKSPACE_EXTENSION' from 'jupyterlab_server' (/usr/local/lib/python3.9/site-packages/jupyterlab_server/__init__.py)

我该如何纠正这个问题？我是否安装了不兼容的软件包版本？

jupyterlab-pygments               0.1.2
jupyterlab-server                 2.10.0

Answer 1

jupyterlab-server 版本 2.10.0 有一个意外的重大更改，已在 2.10.1 中修复。要解决此问题，请升级到 2.10.1（或更新版本）：

pip install jupyterlab-server>=2.10.1

使用 conda-forge 的 conda 安装应该不会受到影响，因为 2.10.0 从未在那里发布过。
