This problem occurs by so many cases, one of the major reasons is installed version of @angular/cli is different to globally installed version of @angular/cli Make sure that both are same version. In other cases you have to update the devkit.

Please have a look on these threads, you will get an idea:

  1. https://github.com/angular/angular-cli/issues/13172
  2. https://github.com/angular/angular-cli/issues/13861
  3. Angular cli build prod: TypeError: Cannot read property 'kind' of undefined

Update your typescript version to 3.8.3 .

OR

Change disableTypeScriptVersionCheck in tsconfig.json file.

"angularCompilerOptions": {
  "disableTypeScriptVersionCheck": true
}
