I follow steps (from turtorial jupyterlab/extension-examples) below and meet this bug

# clone the repository
git clone https://github.com/jupyterlab/extension-examples.git jupyterlab-extension-examples

# go to the extension examples folder
cd jupyterlab-extension-examples

# create a new environment
conda env create

# activate the environment
conda activate jupyterlab-extension-examples

# go to the hello world example
cd hello-world

# install the extension in editable mode
python -m pip install -e .

I tried py3.11, py3.10,py3.8, but all meet the same problem.

By the way, I successfully built my environment and developed my extension a few months ago. After reinstalling anaconda, I found that command failed.

I’ve been stuck for days and I don’t know why
