title: SASS files conversion in blogdown (sam theme)
body: <p>I am trying to build a website using blogdown, and the Hugo theme <a href="https://github.com/victoriadrake/hugo-theme-sam" rel="nofollow noreferrer">Sam</a>.</p>
  
  <p>This theme has SASS files that get converted into a minified css file.
  When I change something in the SASS file, like for example the background color, it is not taken into account when using <code>serve_site</code>.</p>
  
  <p>Is there a way to make this work using <code>blogdown</code>?</p>
  
  <p>A way to reproduce the issue is:</p>
  
  <ul>
  <li>Create an empty directory called for ex. test_sam, and set it as a working directory</li>
  <li>then do:</li>
  </ul>
  
  <pre><code>   library(blogdown)
     new_site(theme = "victoriadrake/hugo-theme-sam")
  </code></pre>
  
  <ul>
  <li>Try to change something in <code>test_sam/themes/hugo-theme-sam/assets/sass/style.sass</code>, for example:</li>
  </ul>
  
  <p>change </p>
  
  <pre><code>html
      background-color: $dark-grey
  </code></pre>
  
  <p>to</p>
  
  <pre><code>html
      background-color: $white
  </code></pre>
  
  <p>This doesn't produce any change.
  Color variables (such as <code>$white</code>) are defined in <code>test_sam/themes/hugo-theme-sam/assets/sass/_vars.sass</code>
  The odd thing is that if I change it to an undefined variable name like <code>$yellow</code>, I get the following error message:</p>
  
  <blockquote>
    <p>Building sites … ERROR 2019/12/27 20:44:39 Transformation failed: SCSS
    processing failed: file "stdin", line 11, col 23: Undefined variable:
    "$yellow".  Total in 197 ms Error: Error building site: logged 1
    error(s)</p>
  </blockquote>
  
  <p>which shows that blogdown does access the sass files to build the site.</p>
  
  <p>I have very little knowledge about website building nor css, so maybe there is something quite obvious that I'm not getting.</p>
  
  <p>Thanks for your help!</p>
