Error when executing npm run grunt default?

Navigation

I have the following files for the GruntJS configuration and thus pass my js files to js.min files

The package.json file: 

  {
  "name": "grunt-primerospasos",
  "version": "1.0.0",
  "description": "Descripcion de mi primer proyecto en gruntjs",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "repository": {
    "type": "git",
    "url": "git+https://gitlab.com/jggj/grunt-primerospasos.git"
  },
  "keywords": [
    "gruntJS"
  ],
  "author": "jggarcia",
  "license": "ISC",
  "bugs": {
    "url": "https://gitlab.com/jggj/grunt-primerospasos/issues"
  },
  "homepage": "https://gitlab.com/jggj/grunt-primerospasos#README",
  "devDependencies": {
    "grunt": "^1.0.1",
    "grunt-contrib-uglify": "^3.1.0"
  },
  "dependencies": {
    "grunt-contrib-uglify": "^3.1.0",
    "grunt": "^1.0.1"
  }
}

and the Gruntfile.js file, like this: 

    module.exports = function (grunt) {
    //Configuraciones del proyecto
    grunt.initConfig({
        //Conf Uglify
        uglify: {
            options: {
                mangle: false,
                compress: {
                    drop_console: true
                }
            },
            js: {
                files:[{
                    cwd: 'js/src/', //ruta de nuestro javascript fuente
                    expand: true,   //ingresar a las subcarpetas
                    src: '*.js'     //patrón relativo a cwd
                    dest: 'js/min/' //destino de los archivos compresos, minificados
                }]
            }
        }
    });

//Cargar grunt-contrib-uglify (plugin)
grunt.loadNpmTasks('grunt-contrib-uglify');

//Registrar la tarea default, esta ejecutara la tarea grunt uglify
grunt.registerTask('default',['uglify']);

};

When I run the npm run grunt default command it gives me the following error: 

    npm ERR! Windows_NT 10.0.15063
npm ERR! argv "C:\Program Files\nodejs\node.exe" "C:\Program Files\nodejs\node_modules\npm\bin\npm-cli.js" "start"
npm ERR! node v6.11.3
npm ERR! npm  v3.10.10

npm ERR! missing script: start

npm ERR!     <https://github.com/npm/npm/issues>

npm ERR! Please include the following file with any support request:
npm ERR!     C:\xampp\htdocs\grunt-primerospasos\npm-debug.log

and in the end I can not convert my js files to minified ones. What could be my mistake?

When I run the npm run grunt default command it gives me the following error:

The command that you have to execute is grunt default

  

grunt default   Running "uglify: js" (uglify) task

     
    

No files created.     Done.

  

It will also work for you if you run grunt , as it performs the default

task by default

Person who does not help you enough, you have to edit this code in some way: 

"scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
},

The safest thing is that if you run npm test you will see that text and it will leave the terminal.

Most likely, you do not have the "start" script defined as the error says: 

"scripts": {
    "start": "node your-script.js"
}

What happens is that you need to start a server node to use grunt, you can take a look here .
