  <p>I tried some solutions I found on the web like installing this: </p>
  
  <pre><code>npm i windows-build-tools
  </code></pre>
  
  <p>but it doesn't work for me.</p>
  
  <p>I got VS2017 installed and also the Platform Toolset v141 as you can see here (last checkbox): <a href="https://gyazo.com/3207242a2bf4fed60dbefd1dc0761f9d" rel="nofollow noreferrer">VS17 Updater</a></p>
