  <p>I tried doing the below steps also.</p>
  
  <pre><code>Edited package.json: Had to change my version for @angular/compiler-cli. In my case I had to bring it back to 5.2.0, as it somehow got to 5.2.10.
  
  Deleted the node_modules directory.
  
  Ran: npm install
  
  Installed: npm install @angular/flex-layout.
  </code></pre>
  
  <p>But again i ran in different errors. I also tried changing the version of flex from <code>"@angular/flex-layout": "^6.0.0-beta.16"</code> to <code>"@angular/flex-layout": "^2.0.0-beta.12"</code> in package.json file but I am still getting these errors.</p>
  
  <p>Can anybody please help me to resolve this issue...?</p>
