How to generate .angular-cli.json file in Angular Cli?

In Angular 6, .angular-cli.json has been replaced with angular.json

For Angular < 6:

Create a new file with name '.angular-cli.json'and add this file in your main directory.

{  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",  "project": {    "name": "my-app"  },  "apps": [    {      "root": "src",      "outDir": "dist",      "assets": [        "assets",        "favicon.ico"      ],      "index": "index.html",      "main": "main.ts",      "polyfills": "polyfills.ts",      "test": "test.ts",      "tsconfig": "tsconfig.app.json",      "testTsconfig": "tsconfig.spec.json",      "prefix": "app",      "styles": [        "styles.css"      ],      "scripts": [],      "environmentSource": "environments/environment.ts",      "environments": {        "dev": "environments/environment.ts",        "prod": "environments/environment.prod.ts"      }    }  ],  "e2e": {    "protractor": {      "config": "./protractor.conf.js"    }  },  "lint": [    {      "project": "src/tsconfig.app.json",      "exclude": "**/node_modules/**"    },    {      "project": "src/tsconfig.spec.json",      "exclude": "**/node_modules/**"    },    {      "project": "e2e/tsconfig.e2e.json",      "exclude": "**/node_modules/**"    }  ],  "test": {    "karma": {      "config": "./karma.conf.js"    }  },  "defaults": {    "styleExt": "css",    "component": {}  }}

Since Angular version 6 .angular-cli.json is deprecated. That file was replaced by angular.json file which supports workspaces.

I got this same error in my current project and was confused because I'm running the application / ng serve in one terminal, but got this when I tried to generate a component from another terminal. .angular-cli.json was already there and correct. So what gives?

I realized that I used the shortcut to open VisualStudio Code's internal terminal -- which opened the terminal to the *root of the project * (like most IDEs). The project contains other things in addition to the Angular application folder that has the .angular-cli.json file in question. I just had to cd to the right folder and run ng g c again and things were fine.

In my case it was just a silly error. I thought I'd come back to share in order to save people a real headache for something so simple. I see that Shiva actually has mentioned this above, but I thought I would give a bit more detail so it doesn't get overlooked.
