Check to make sure you have the correct package.json file. There will be a scripts block with all the npm commands available to the app.

Example:

"scripts": {

    "build": "dt-app build --prod",

    "start": "dt-app dev",

    "generate:function": "dt-app generate function",

    "generate:action": "dt-app generate action",

    "uninstall": "dt-app uninstall",

    "deploy": "dt-app deploy",

    "update": "dt-app update",

    "info": "dt-app info",

    "help": "dt-app help",

    "lint": "eslint ."

  }

You may simply be missing the `start` script that should be located in in the `package.json` file. I would verify that this script actually exists before running.
