title: installing npm in Laravel in order to use Bootstrap in my project
body: <p>i'm new to laravel and it's been a while that i'm trying to install bootstrap files(css and js) .
  i first did this in cmd :</p>
  
  <pre><code>composer require laravel/ui --dev
  </code></pre>
  
  <p>which ended in </p>
  
  <blockquote>
    <p>Package manifest generated successfully.</p>
  </blockquote>
  
  <p>then :</p>
  
  <pre><code>php artisan ui bootstrap
  </code></pre>
  
  <p>that showed me :</p>
  
  <blockquote>
    <p>Bootstrap scaffolding installed successfully.
    Please run "npm install &amp;&amp; npm run dev" to compile your fresh scaffolding.</p>
  </blockquote>
  
  <p>but now when i execute <code>npm install</code> in cmd , it shows me an error :</p>
  
  <blockquote>
    <p>'npm' is not recognized as an internal or external command,
    operable program or batch file.</p>
  </blockquote>
  
  <p>what the hell is wrong with it ??</p>
