What have worked for me was:

1.) Make sure your angular version starts with 7.2.15 (if not, you should install this version first) 2.) Be sure your Node version is 12.x.x 3.) Typescript version 3.4.5 3.) ng update @angular/cli @angular/core (for @angular/cli, be sure to install it both local & global) 4.) npm uninstall @angular-devkit/build-angular 5.) npm install @angular-devkit/build-angular 6.) ng update --all 7.) If you have ViewChild on your application, be sure to edit them with: Source

@ViewChild(<name>, {static: true}) <name>; // Adding static: true on the 2nd param
