I downloaded the jekyll-theme-clean-blog theme and successfully built it locally.
Once I move it to github pages, I get the following build error:
Your SCSS file assets/main.scss has an error on line 2: File to import not found or unreadable: ../assets/vendor/startbootstrap-clean-blog/scss/clean-blog.scss. Load paths: _sass /hoosegow/.bundle/ruby/2.7.0/gems/jekyll-theme-primer-0.5.4/_sass /hoosegow/.bundle/ruby/2.7.0/gems/jekyll-theme-primer-0.5.4/_sass.
I added
sass: sass_dir: _sass style: :compressed
to config file, still wont build on github pages.
Any help would be much appreciated.
GitHub Pages only supports a select number of themes (https://pages.github.com/themes/) listed below:
The one you've named isn't in that list. Basically this is the same issue as not being able to use Jekyll plugins. The solutions there are to use a different hosting solution, or commit the built output of your site to a repo.
