JupyterLab 4.2.0: ImportError: cannot import name 'get_allowed_levels' from 'jupyterlab_server.config'

Description

Opened JupyterLab and was notified of a newer version 4.2.0, so I exited Jupyter, and used conda install jupyterlab=4.2.0 at the (base) conda prompt.

Typing jupyter lab at (base) to launch, results in the following error:

(base) D:\users\trent\Dropbox\PythonProjects>jupyter lab

Traceback (most recent call last):
  File "C:\Users\trent\anaconda3\Scripts\jupyter-lab-script.py", line 5, in <module>
    from jupyterlab.labapp import main
  File "C:\Users\trent\anaconda3\Lib\site-packages\jupyterlab\labapp.py", line 26, in <module>
    from .commands import (
  File "C:\Users\trent\anaconda3\Lib\site-packages\jupyterlab\commands.py", line 32, in <module>
    from jupyterlab_server.config import (
ImportError: cannot import name 'get_allowed_levels' from 'jupyterlab_server.config' (C:\Users\trent\anaconda3\Lib\site-packages\jupyterlab_server\config.py)

jupyterlab_server 2.25.1 py311haa95532_0 is being used.

Reproduce

Launch jupyter lab at the (base) conda prompt

Expected behavior

I expect jupyterlab to launch

JupyterLab 4.2.0 requires jupyterlab_server>=2.27.1,<3 but you have 2.25.1 installed:

jupyterlab/pyproject.toml

Line 47 in 66bc3b0

"jupyterlab_server>=2.27.1,<3",

Most likely you installed some packages using pip and some using conda which leads to incorrect resolution of dependencies.

I was able to do conda search -f jupyterlab_server to get the current version and install it.

This was a new Anaconda installation, and I know better than to use pip in my Anaconda distribution.

Thanks for the reply and for confirmation it is not pip/conda issue. It looks like the dependency pin on conda-forge was wrong, even though it was correct in RC. New builds generated after conda-forge/jupyterlab-feedstock#434 was merged should fix this.
