title: `npm install` fails on node-gyp rebuild with `gyp: No Xcode or CLT version detected!`
body: <p>Every time I try <code>npm install</code>. I get the following error. How do I fix it?</p>
  <pre><code>gyp: No Xcode or CLT version detected!
  </code></pre>
  <p>I am on <code>node -v → v8.8.0</code> &amp; <code>npm -v → v6.11.3</code></p>
  <p>I tried to run it on VSCode terminal and iTerm, but both ended up getting the same error. (both are updated to the latest version). The only new thing I did is updating my macOS to the latest version (Catalina 10.15.3 today).</p>
