Answer 1

Looks like your Angular CLI is v6+, and your Angular App is v2. There must be angular-cli.json file in your project. In the latest version of CLI, after v6, config. file is renamed with angular.json with slighter changes. Please create angular.json file and update it accordingly, if this is the case.

Otherwise, just create a new project using ng new <appName> and hit ng serve . As Angular CLI is the latest installed in your machine, so it will create angular.json by default.

Answer 2

Yes looks like your Angular project is outdated, the newest Angular uses angular.json , not angular-cli.json .

Either ask the creator to update it or do it yourself by following this: https://update.angular.io/
