title: Couldn't read tsconfig.base.json! - Apollo Angular project setup
body: <pre><code>ng add apollo-angular
  </code></pre>
  <p>It threw a number of warnings:</p>
  <pre><code>UPDATE src/app/app.module.ts (541 bytes)
  npm WARN notsup Unsupported engine for extract-files@9.0.0: wanted: {&quot;node&quot;:&quot;^10.17.0 || ^12.0.0 || &gt;= 13.7.0&quot;} (current: {&quot;node&quot;:&quot;10.16.3&quot;,&quot;npm&quot;:&quot;6.12.0&quot;})
  npm WARN notsup Not compatible with your version of node/npm: extract-files@9.0.0
  npm WARN karma-jasmine-html-reporter@1.5.4 requires a peer of jasmine-core@&gt;=3.5 but none is installed. You must install peer dependencies yourself.

  npm WARN @apollo/client@3.1.3 requires a peer of subscriptions-transport-ws@^0.9.0 but none is installed. You must install peer dependencies yourself.
  </code></pre>
  <p>So after adding the peer dependencies I try to add apollo-angular one more time:</p>
  <pre><code>MIA-LT-16354:src SSilwal$ ng add apollo-angular
  Skipping installation: Package already installed
