Usbin grunt: file JavaScript concatenato non creato

Question

Sto utilizzando l'attività usemin nel mio generatore Yeoman. Nell'HTML sembra che abbia funzionato correttamente poiché i file JavaScript separati sono sostituiti da un collegamento a un singolo file. Tuttavia, il file a cui si fa il riferimento non è stato creato. Mi manca un'impostazione?

Gruntfile.js

'use strict'; 

module.exports = function (grunt) { 
    // load all grunt tasks 
    require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks); 

    // configurable paths 
    var yeomanConfig = { 
     app: 'app', 
     dev: 'dev', 
     dist: 'dist' 
    }; 

    grunt.initConfig({ 
     yeoman: yeomanConfig, 

     clean: { 
      dist: { 
       files: [{ 
        dot: true, 
        src: [

Answer 1

Si sta andando ad avere bisogno di concat e compiti min dopo usemin. Usemin cambia semplicemente la configurazione per concat.

In uno dei miei progetti, ho le seguenti:

<!-- build:js /js/scripts.min.js --> 
    <script src="/assets/javascript/source/index.js"></script> 
    <script src="/assets/javascript/source/flipper.js"></script> 
    <script src="/assets/javascript/source/utils.js"></script> 
    <script src="/assets/javascript/source/overlay.js"></script> 
    <script src="/assets/javascript/source/views.js"></script> 
    <script src="/assets/javascript/source/rotator.js"></script> 
    <script src="/assets/javascript/source/promos.js"></script> 
    <!-- endbuild --> 

e il mio compito Grunt è questo:

grunt.registerTask('produce', [ 
    'useminPrepare', 
    'concat', 
    'uglify', 
    'cssmin', 
    'usemin' 
]); 

Hai semplicemente bisogno di avere concat & uglify installato al vostro progetto, non c'è nessuna configurazione necessaria dal momento che usemin lo gestisce.
