title: Adding bootstrap in Symfony 4
body: <p>In my Symfony 4 project, I try to add bootstrap as an import after</p>
  
  <pre><code>yarn add bootstrap --dev
  </code></pre>
  
  <p>As I follow documentation, I tried to import bootstrap as follows:</p>
  
  <pre><code>@import "~bootstrap/scss/bootstrap";
  </code></pre>
  
  <p>When I run <strong>yarn encore dev</strong>, it says module not found. </p>
  
  <p>Than I tried this:</p>
  
  <pre><code>@import "../../node_modules/bootstrap/scss/bootstrap.scss";
  </code></pre>
  
  <p>The output is:</p>
  
  <pre><code>Syntax Error: ModuleNotFoundError: Module not found: Error: Can't resolve './alert' in 'C:\Users\tolga\GIT\artifex\node_modules\bootstrap\scss'
  </code></pre>
  
  <p>What am I missing? alert.scss is there but it cannot find module. What should I try?</p>
