Panel: MaterialTemplate, BootstrapTemplate, GoldenTemplate not working - GET 404 when requesting bundled assets

[MarcSkovMadsen]

I have installed the latest version of the Panel Master Branch and reinstalled my conda environment following the developer guide. I get an error during the installation https://github.com/holoviz/panel/issues/1652. But I believe Panel, Bokeh etc. is still installed and I can run what I need. I have also successfully run panel build panel.

If I replace VanillaTemplate with MaterialTemplate in the file panel\tests\template\test_vanilla_manual.py I get

$ python -m panel serve 'panel\tests\template\test_vanilla_manual.py' --dev

[philippjfr]

You have to install them correctly by running pip install -e . or python setup.py develop. The assets are now bundled and need to be collected before this works.

[MarcSkovMadsen]

Ok. But I guess then that this issue is about the Developer Guide needs to be updated?

[philippjfr]

Already on it.

[MarcSkovMadsen]

Also when I run

$ python setup.py develop
Traceback (most recent call last):

    % (js_version, version))
ValueError: panel.js version (0.10.0-a33) does not match panel version (0.10.0a34+g3961571a-dirty). Cannot build release.

[philippjfr]

My fault, will fix momentarily. Need a pre-commit hook to make sure I've done that before tagging a dev release.

[philippjfr]

If you want to fix it locally for you just bump the number to a34 in package.json and package-lock.json.

[MarcSkovMadsen]

After bumping to a34 there is still a requests error.

[philippjfr]

Ah, okay, sorry for being the guinea pig here but glad this is getting caught. Will have to add that dependency to the pyproject.toml.

[MarcSkovMadsen]

It's strange. Because it does not help me to add it to pyproject.toml. And requests is installed in my environment.

[MarcSkovMadsen]

Ahh. The problem is no longer requests. Its ipywidgets_bokeh

        __import__(imp)                        dg
    ModuleNotFoundError: No module named 'ipywidgets_bokeh'

[MarcSkovMadsen]

Maybe it would be an idea to setup some CI/ CD that replicates the steps of the Developer Guide?

[MarcSkovMadsen]

I've added ipywidgets_bokeh to the pyproject.toml file. Now the problem is

The CI does do that but it's on linux, we need to set up GitHub actions to run it on OSX and Windows too.

[philippjfr]

Okay, fixed the requirement on ipywidgets_bokeh, added the developer docs, added requests to the pyproject.toml. Now just need to track down that encoding problem.

[philippjfr]

Okay, pushed a fix for that, could you try out the PR?

[philippjfr]

Will merge and get a dev release out but would very much appreciate the testing. I'll test everything on my Windows machine later but might take me a while.

[xavArtley]

I have tested python setup.py develop on the last commit all seems working now

[philippjfr]

Thanks @xavArtley, I appreciate it. Overall I'm very happy about the bundling work, by default everything is now loaded from the server itself, which means most things can be run even when there's not internet available. There's also no more inlined CSS and everything can fall back cleanly to CDN resources if requested.

[MarcSkovMadsen]

FYI. I did a git pull holoviz master and ran python setup.py develop with success.
