I am getting Error as below:

./cache-busting.js

'.' is not recognized as an internal or external command,

Is there any solution ? Or is there anything I am missing?

I run npm run build to build the application.

In your package.json file, add "postbuild": "node ./cache-busting.js" after your build scripts like:

"scripts": {
        "start": "ionic-app-scripts serve",
        "clean": "ionic-app-scripts clean",
        "build": "ionic-app-scripts build",
        "postbuild": "node ./cache-busting.js",
        "lint": "ionic-app-scripts lint",
        "docs": "./node_modules/.bin/compodoc -d ./docs/ -p ./tsconfig.json --theme vagrant",
        "serve-docs": "./node_modules/.bin/compodoc -s -d ./docs"
    }
