grunt-contrib-watch livereload not reloading

Question

我已经尝试了一整天让这个负载工作，但我被难住了。我的grunt.js文件在下面，我确保在html文件的末尾添加了我的脚本。有什么想法吗？

module.exports = function(grunt) {
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-compass');
grunt.initConfig({
    uglify: {
        my_target: {
            files: {
                '_/js/script.js' : ['_/components/js/script.js']
            }//files
        } //mytarget
    }, //uglify
    watch: {
        options : { livereload: true },
        scripts: {
        files: ['_/components/js/*.js'],
        tasks: ['uglify']
    }, //scripts
    html: {
        files: ['*.html']
    }//html
    }//watch
}) // initconfig
grunt.registerTask('default', 'watch');
} //exports

尝试使用浏览器extension进行livereload。

我为你录制了一小段gif动画截屏。在这里，我展示了如何通过npm安装依赖模块，以及如何在启用livereload的情况下构建项目。

我的工具版本是NPM 1.4.21和NodeJS v0.10.30

这是我的Gruntfile.js和评论

module.exports = function (grunt) {

  grunt.initConfig({

    pkg: grunt.file.readJSON('package.json'),

    // Delete contents before the full build
    clean: {
      dist: ['dist', 'dist/js'],
      html: ['dist/**/*.html']
    },

    /* Uglify javascript located in app/js/*.js
       And copy it to dist/js/main.js

       So all JS will be in one file.
       P.S. Remember that our js task in uglify is called "js" */
    uglify: {
      options: {
        report: 'min'
      },
      js: { // task to combine separate files into main.js
        files: {
          'dist/js/main.js': [
            'app/js/**/*.js'
          ]
        }
      }
    },

    copy: { // Just copy HTML files from app folder
      html: {
        files: [{
          expand: true,
          cwd: 'app/',
          src: ['**/*.html'],
          dest: 'dist/',
          filter: 'isFile'
        }]
      },
    },

    connect: { // Create server that will serve
               // requests to our compiled app
      dist: {
        options: {
          port: 3000,
          base: 'dist'
        }
      }
    },

    watch: { // Most instersting.
             // Will be watching for changes in JS and HTML.
      options: {
        livereload: true
      },
      js: { // Here you need to specify the same task name
            // as in uglify task we thought above
        files: ['app/js/**/*.js'], // Which files to uglify and copy
        tasks: ['newer:uglify'] // Do it
      },
      copy: { // Remove old html and copy new to dist folder
        files: ['app/**/*.html'],
        tasks: ['clean:html','newer:copy:html']
      }
    },

  });

  // Load all grunt modules with one command
  require('load-grunt-tasks')(grunt);

  grunt.registerTask('build', [
    'clean:dist', // Remove all
    'uglify', // Uglify all
    'copy' // Copy all HTML
  ]);

  grunt.registerTask('default', [
    'build', // Build the project
    'connect:dist', // Start server
    'watch' // Watch for changes
  ]);

};

这是package.json，没有任何评论(一切都足够清楚了)

  "engines": {
    "node": ">= 0.10.0"
  },
  "devDependencies": {
    "grunt": "~0.4.5",

有几个选项可以让实时重新加载工作：

中间件浏览器扩展：http://feedback.livereload.com/knowledgebase/articles/86242-how-do-i-install-and-use-the-browser-extensions-

• add a javascript行：<script src="//localhost:35729/livereload.js"></script>

• connect
