title: SCSS file error: File to import not found or unreadable: bootstrap
body: <p>I am trying to set up a site ran on Jekyll I haven't updated in awhile (obviously my developer skills are very rusty in general) with Github Pages. Whenever I try, I get this error:
   Your site is having problems building: Your SCSS file sass/about.scss has an error on line 1: File to import not found or unreadable: default. Load paths: _sass /hoosegow/.bundle/ruby/2.4.0/gems/minima-2.1.1/_sass. For more information, see <a href="https://help.github.com/articles/page-build-failed-invalid-sass-or-scss/" rel="noreferrer">https://help.github.com/articles/page-build-failed-invalid-sass-or-scss/</a>.</p>
  
  <p>All my scss pages like about.scss start with this:</p>
  
  <pre><code>---
  ---
  
  @import "default";
  </code></pre>
  
  <p>or </p>
  
  <pre><code>---
  ---
  
  @import "bootstrap";
  </code></pre>
  
  <p>I have made sure that my config.yml file has this:</p>
  
  <pre><code>sass:
    sass_dir: ./_sass
  </code></pre>
  
  <p>and I am not sure what to do from here.</p>
