title: Ionic app: an unhandled exception occurred: Could not find module “@angular-devkit/build-angular/src/angular-cli-files/models/webpack-configs/utils”
body: <p>I created an empty blank ionic app (without capacitor), added the cordova plugin and install the google-plus package.</p>
  <p>In the devDependecies section of the packages.json I have:</p>
  <pre><code>&quot;@angular-devkit/build-angular&quot;: &quot;^0.1100.1&quot;,
  &quot;@angular-devkit/core&quot;: &quot;^11.0.1&quot;,
  &quot;@angular/cli&quot;: &quot;~10.0.5&quot;,
  &quot;@angular/compiler&quot;: &quot;~10.0.0&quot;,
  &quot;@angular/compiler-cli&quot;: &quot;~10.0.0&quot;,
  &quot;@angular/language-service&quot;: &quot;~10.0.0&quot;,
  </code></pre>
  <p>I proceeded in building the app by doing:</p>
  <blockquote>
  <p>ionic cordova build android --prod --release --verbose</p>
  </blockquote>
  <p>But I get the exception:</p>
