Jupyter lab build fails on windows subsystem linux with errno 13 Permission denied

I am trying to to run the jupyter lab build without success. I installed a venv with pyenv running python 3.8.5.

I’ll post below the command outputs for

jupyter labextension list
jupyter lab build
cat /tmp/jupyterlab-debug-5vr2zquq.log
jupyter labextension install @jupyter-widgets/jupyterlab-manager --minimize=False

Any advice would be appreciated. I have no idea how to fix this.
Thanks

❯ jupyter labextension list
JupyterLab v3.0.16
/home/bebop/.local/share/jupyter/labextensions
@jupyter-widgets/jupyterlab-manager v3.0.0 enabled OK (python, jupyterlab_widgets)

/mnt/s/dokumente/Privat/neue_fische/ot/ot-sopra_steria/.venv/share/jupyter/labextensions
jupyterlab-plotly v5.1.0 enabled OK

Other labextensions (built into JupyterLab)
app dir: /mnt/s/dokumente/Privat/neue_fische/ot/ot-sopra_steria/.venv/share/jupyter/lab

Build recommended, please run jupyter lab build:
plotlywidget needs to be included in build

❯ jupyter lab build
[LabBuildApp] JupyterLab 3.0.16

[LabBuildApp] Building jupyterlab assets (production, minimized)
Build failed.
Troubleshooting: If the build failed due to an out-of-memory error, you
may be able to fix it by disabling the dev_build and/or minimize options.

If you are building via the jupyter lab build command, you can disable
these options like so:

jupyter lab build --dev-build=False --minimize=False

You can also disable these options for all JupyterLab builds by adding these
lines to a Jupyter config file named jupyter_config.py:

c.LabBuildApp.minimize = False
c.LabBuildApp.dev_build = False

If you don’t already have a jupyter_config.py file, you can create one by
adding a blank file of that name to any of the Jupyter config directories.
The config directories can be listed by running:

jupyter --paths

Explanation:

  • dev-build: This option controls whether a dev or a more streamlined
    production build is used. This option will default to False (i.e., the
    production build) for most users. However, if you have any labextensions
    installed from local files, this option will instead default to True.
    Explicitly setting dev-build to False will ensure that the production
    build is used in all circumstances.

  • minimize: This option controls whether your JS bundle is minified
    during the Webpack build, which helps to improve JupyterLab’s overall
    performance. However, the minifier plugin used by Webpack is very memory
    intensive, so turning it off may help the build finish successfully in
    low-memory environments.

Hey are you running the command as root in WSL? If so, npm v6 refuses to do this by default and change the uid of the user running the npm command.

Hi fcollonval,

that’s a good point you are making. I don’t use sudo to install anything.
