Jekyll site stopped working, but nothing changed

Question

My jekyll sight had been running fine for a while until I add a blog post, which works perfectly locally, but then I get an error via email from GitHub saying

SCSS file Desktop/my-blog/css/style.scss has an error on line 1: File to import not found or unreadable: ../_sass/bootstrap. Load path: /hoosegow/.bundle/ruby/2.4.0/gems/jekyll-theme-primer-0.4.0/_sass.

I went to report this as an issue on the theme I was using, but I noticed that others were having similar build issues with Jekyll. Here's the link to that thread

Also, here is my style.css file, which seems to be causing the error.

Any advice is extremely helpful!

Answer 1

The error is telling you that the file bootstrap.scss can't be imported; either because it isn't in the location specified (the theme /_scss/ directory) or because it isn't called bootstrap.scss. The link you posted seems completely unrelated.
