plotly.py: Jupyter Lab extensions fail to build

OK I’ve pushed up versions 1.5.2 of the extensions, so that should resolve the current issue!

The root cause of this problem appears to be a bad version of https://www.npmjs.com/package/@types/plotly.js which is something we depend on but do not maintain.

In principle I could just pin the version to a known-working one here: https://github.com/plotly/plotly.py/blob/master/packages/javascript/jupyterlab-plotly/package.json#L35 and release versions 1.5.2 of our extensions. I will try to do this tonight (Pacific Time).

Thanks for your quick work on this. I followed the instructions here again, changing all @1.5.1 references to @1.5.2 and the installation and build worked perfectly.

@peterblazejewicz yes, thanks, your comment above pointed the way. I rather wish that the types project did a bit more QA on stuff like this 😉

Extremely helpful, thank you @matdecac ! This error doesn’t have the same cause as the one I have previously encountered, so I will have to investigate more fully next week.

If anyone else encounters an installation problem, please continue to provide similar details so I can determine if we have one or many issues to tackle 😃

OK I think I have enough info to fix this, I should have a fix in a day or two, thanks for the information everyone!

Hi, I have the same issue. It appeared suddenly. Two days ago, build was successful. Today, I created a new conda env (copy from a environment.yml with the exact same packages) and it fails. Here is the output of jupyter labextension list

JupyterLab v1.2.6
Known labextensions:
   app dir: C:\Users\Samuel.PALVADEAU\projects\OpenClassRooms\DataAnalyst\P6\conda-env\share\jupyter\lab
        @jupyter-widgets/jupyterlab-manager v1.1.0 enabled  ok
        @jupyterlab/toc v1.0.1 enabled  ok
        jupyterlab-plotly v1.5.1 enabled  ok
        plotlywidget v1.5.1 enabled  ok

Build recommended, please run `jupyter lab build`:
    @jupyter-widgets/jupyterlab-manager needs to be included in build
    plotlywidget needs to be included in build
    jupyterlab-plotly needs to be included in build

and the log file
