title: The Angular Compiler requires TypeScript >=4.2.3 and <4.3.0 but 4.4.0-dev.20210724 was found instead
body: <p>The Angular Compiler requires TypeScript &gt;=4.2.3 and &lt;4.3.0 but 4.4.0-dev.20210724 was found instead.
  I have understood one thing that whenever error like this occurs you should type this command:</p>
  <pre><code>npm i -D typescript@4.2.6 
  </code></pre>
  <p>You should keep guessing the right number between 4.2.3 and 4.3.0 I got 4.2.4 as a correct guess.</p>
