Javascript Grunt CSS和JS文件不在

我正在开发一个web应用程序，并尝试使用Grunt Build加载以下样式表。当使用Grunt服务时，它们都可以很好地加载，但是当使用Grunt构建加载时，样式表无法加载

<!-- build:css styles/vendor.css -->
<link rel="stylesheet" href="../bower_components/bootstrap/dist/css/bootstrap.css" />
<link rel="stylesheet" href="styles/main.css" />
<link rel="stylesheet" href="styles/ol.css" />
<!-- endbuild -->

我的GrunFile.js如下：

// Generated on 2015-05-01 using generator-angular 0.11.1
'use strict';

// # Globbing
// for performance reasons we're only matching one level down:
// 'test/spec/{,*/}*.js'
// use this if you want to recursively match all subfolders:
// 'test/spec/**/*.js'

module.exports = function (grunt) {

  // Load grunt tasks automatically
  require('load-grunt-tasks')(grunt);

  // Time how long tasks take. Can help when optimizing build times
  require('time-grunt')(grunt);

  // Configurable paths for the application
  var appConfig = {
    app: require('./bower.json').appPath || 'app',
    dist: 'dist'

  // Define the configuration for all the tasks
  grunt.initConfig({

    // Project settings
    yeoman: appConfig,

    // Watches files for changes and runs tasks based on the changed files
