Theme error: no theme named 'pydata_sphinx_theme'

[shapiromatron]

I get an error in configuration when running sphinx-autobuild, but it works just fine when using the standard sphinx-build.

I'm using the pydata-sphinx-theme.

► sphinx-build -b html source build/html
... build succeeded.

► sphinx-autobuild -b html source build/html
sphinx_args.filenames=[]
[sphinx-autobuild] > sphinx-build -b html source build/html
Running Sphinx v7.2.6
loading pickled environment... done

Theme error:
no theme named 'pydata_sphinx_theme' found (missing theme.conf?)
Sphinx exited with exit code: 2

The rendered output looks fine with the standard build command, I'm not sure what the issue is. Any ideas?

I was able to fix it by adding import pydata_sphinx_theme to my conf.py file, but it seems odd (or at least different than sphinx core) that it's required for autobuild to resolve the theme information.

Hmm, sphinx-autobuild literally just calls sphinx-build under the hood. Could you run things in verbose mode and, possibly, also print sys.path from conf.py to gather more diagnostics on this.

Also, are both Sphinx and sphinx-autobuild installed in the same directory?
