Keep receiving a warning by mail for page building about bulma-clean-theme

Thanks for bearing with me.

It seems you can remove the need for theme: bulma-clean-theme in your _config.yml file completely if you add gem 'github-pages', group: :jekyll_plugins to your Gemfile and then add github-pages to your plugins in _config.yml

plugins:
  - jekyll-sitemap
  - jekyll-paginate
  - jekyll-redirect-from
  - github-pages

Then run bundle update.

Now when you run bundle exec jekyll serve locally it should build using the specified remote_theme as per GitHub Pages build.

When working locally I set my _config.yml as follows with both remote_theme and theme.

theme: bulma-clean-theme
remote_theme: chrisrhymes/bulma-clean-theme

and when I push to github pages I comment out the theme to avoid getting the warning email, but leave the remote_theme setting

#theme: bulma-clean-theme
remote_theme: chrisrhymes/bulma-clean-theme

I contacted github pages support about this in February this year and they said to use github-pages gem to resolve the issue, but at that time the gem required an old version of Jekyll. It looks like the latest version of github-pages gem now uses Jekyll 3.8.5.

So every time I work locally or I push my changes to GitHub, I need to modify these settings ?

[chrisrhymes]

This is what I do currently but it’s not ideal. I will try and add GitHub pages gem to a test site this weekend to see if this resolves the need for changing settings.

Okay, so I tried it and it seems to be working. But I get an error when running bundle exec jekyll serve: Invalid theme folder: _sass.
Is this folder needed or not ?

[chrisrhymes]

Glad its working for you.
For the invalid theme folder message, it looks like this is a warning, rather than an error, from Jekyll when using a remote_theme instead of theme.
