Answer 1

Angular 6 looks for angular.json instead of angular-cli.json.

You need to update your @angular/cli. Adding to the above answer

I did update all the package with the following commands and updated all dependencies too. So as to remove all compatibility issues with other packages.

If you are starting your app or demo app, follow this procedure. Be extra careful if you are doing this for production app.

npm install -g npm-check-updates
ncu -u
ng update @angular/cli
npm install

Install npm-check-updates

npm install -g npm-check-updates 

Use ncu to update your package.json

ncu for display

ncu -u for re-writing your package.json

Update your @angular/cli to modify your application to be compatible with angular 6

ng update @angular/cli 

and run npm install to update your packages
