Hi everybody! I hope this information helps you find a solution. I contacted upstream sphinx-theme-builder a few days ago about why the relaxation flags in Nodejs weren't working: export STB_USE_SYSTEM_NODE = true export STB_RELAX_NODE_VERSION_CHECK = true He answered me this here: https://github.com/pradyunsg/sphinx-theme-builder/issues/50
According to him, the version currently in Debian NodeJS v16.13.2 is incompatible. There are even other problems related to this here too: https://github.com/pradyunsg/sphinx-theme-builder/issues?q=is%3Aissue+is%3Aclosed Another thing we have another problem similar to this: https://salsa.debian.org/python-team/packages/sphinx-book-theme https://github.com/executablebooks/sphinx-book-theme/blob/master/pyproject.toml In the new version 1.1.3, Upstream adopted sphinx-theme-builder as a backend And the aggravating factor is that the majority of dependencies. js is not in Debian. I believe the solution for pydata-sphinx-theme will work for sphinx-book-theme Nilson F. Silva
