Can't install any jupyterlab extensions in docker image

Question

I am running docker build task in Azure pipelines on a pipeline agent that runs on an on-prem host. I am trying to "RUN jupyter labextension install @jupyter-widgets/jupyterlab-manager".

In the base image:
node=14.14.0
jupyter=1.0.0
jupyter-packaging = 0.7.12
jupyter-resource-usage= 0.5.1
jupyter_client = 6.1.7
jupyter_console = 6.2.0
jupyter_core = 4.7.0
jupyter_server = 1.6.1
jupyter_telemetry = 0.1.0
jupyterhub = 1.3.0
jupyterhub-base = 1.3.0
jupyterlab = 3.0.12
jupyterlab-git = 0.30.0b2
jupyterlab-templates = 0.2.5
jupyterlab_code_formatter=1.4.5
jupyterlab_pygments = 0.1.2
jupyterlab_server = 2.3.0

Dockerfile looks like this:

USER root
COPY files/.npmrc $HOME/.npmrc
RUN jupyter labextension install --no-build @jupyter-widgets/jupyterlab-manager .....

.npmrc looks like so:

always-auth=true
strict-ssl=false
registry=https://pkgs.dev.azure.com/org-name/proj-name/_packaging/proj-name/npm/registry/
https-proxy=the-proxy-url
proxy=the-proxy-url

The pipeline does the following tasks:

Runs npmAuthenticate task on .npmrc to edit the .npmrc file with the auth-token. This succeeds..
Next runs docker build. The Dockerfile instructs to copy this modified .npmrc to $HOME and tries to install lab extensions

Found this thread : https://github.com/jupyter-widgets/ipywidgets/issues/1982#issuecomment-468716770
We use jupyterlab v3. So node>=12 is required. So I changed the Dockerfile to:

USER root
COPY files/.npmrc $HOME/.npmrc
RUN conda remove nodejs && conda install -c conda-forge nodejs=12 && conda list | grep nodejs &&
jupyter labextension install --no-build @jupyter-widgets/jupyterlab-manager .....

Tried this also: https://stackoverflow.com/a/52484330/3575135 . Didnt help

The normal "npm install @angular/cli" works. But the lab extensions are giving me a hard time. Nothing seems to be working at this point..

This is the error:

ValueError: "@jupyter-widgets/jupyterlab-manager" is not a valid npm package

Please help!

Answer 1

You should NOT be installing Node.js nor @jupyter-widgets/jupyterlab-manager for JupyterLab 3.0+. The extension system has been improved and the new "federated extensions" system no longer requires Node.js (and majority of extensions have migrated away from Node.js requirement). The readme of @jupyter-widgets/jupyterlab-manager clearly states that for JupyterLab 3.0+ you should use:

pip install jupyterlab_widgets

The same goes for most extensions – they will have a name of the PyPI package in their readme if they migrated. For more in-depth explanation please read this answer.

As a good advice please only use jupyter labextension install for extensions that have not migrated to pip/conda-installable federated extensions.

Answer 2

Copied the npmrc to /.npmrc instead of $HOME/.npmrc. This worked

Answer 3

@krassowski this not correct at all. Running

jupyter labextension install

yields this:

(Deprecated) Installing extensions with the jupyter labextension install command is now deprecated and will be removed in a future major version of JupyterLab.

Users should manage prebuilt extensions with package managers like pip and conda, and extension authors are encouraged to distribute their extensions as prebuilt packages
