JupyterLab 因 AssertionError 而无法运行

我用过pip 安装 JupyterLab在我运行 Pop!_OS 的机器上。安装成功，但当我尝试运行该程序时，出现以下错误：

Traceback (most recent call last):
  File "/home/foof/.local/bin/jupyter-lab", line 5, in <module>
    from jupyterlab.labapp import main
  File "/home/foof/.local/lib/python3.10/site-packages/jupyterlab/labapp.py", line 11, in <module>
    from jupyter_core.application import JupyterApp, NoStart, base_aliases, base_flags
  File "/home/foof/.local/lib/python3.10/site-packages/jupyter_core/application.py", line 16, in <module>
    from traitlets import Bool, List, Unicode, observe
  File "/home/foof/.local/lib/python3.10/site-packages/traitlets/__init__.py", line 5, in <module>
    from ._version import __version__, version_info
  File "/home/foof/.local/lib/python3.10/site-packages/traitlets/_version.py", line 7, in <module>
    assert __version__ == (
AssertionError

我已经重新安装了 Python 和 pip，但总是出现相同的错误。有什么指示吗？

看起来答案是改变特质版本编辑

~/.local/lib/python3.10/site-packages/traitlets/_version.py

读书：

version_info = (5, 2, 2)
__version__ = "5.2.2"
