KeyError when trying to build almost empty docs

[funkyfuture]

hello, i'm trying to port an existing Sphinx-powered documentation to use this theme and i'm hitting some problems. therefore i set up a fresh Sphinx project for fiddling around, but with hardly any contents, the build fails.

steps to reproduce:

1. set up and activate a virtual environment
2. pip install sphinx-immaterial
3. sphinx-quickstart
4. add sphinx_immaterial to extensions and set as HTML theme
5. make html

addendum, when i do the same, but with an editable installation of the current main branch, it yields:

the …/sphinx_immaterial/bundles directory exists nowhere.

The first error is fixed by deleting your old build directory. The second error is because you need to run the nodejs-based build step. Did you use pip install -e . to create the editable install?

As for the absent sphinx_immaterial/bundles folder, that should be generated at install time with

npm install
npm run build

executed from setup.py.

maybe i oversaw it, but a hint that a clean is always required would be helpful then. or, if it's a requirement, should the builder make sure of it?

indeed, but the static_bundles command isn't invoked.

otherwise that helped to get started, thanks!

We often see this when the old build used a different theme. I don't think of it as a requirement, rather good practice to start a fresh build when switching themes (or testing mods of a theme).

a'ight, i'll propose an addition for the Getting Started section.

In this case the issue is due to the sphinx-immaterial monkey patching of the search index generation code in Sphinx. In fact it could make sense to add something to the search index code to deal with this automatically, since quite a few users have run into this issue.

Hi,

has the issue been resolved yet? I am still facing this same issue.

[2bndy5]

The current solution is to purge any previous docs build. Are you switching from a different theme? That seems to be the most likely culprit here.
