Grunt watch Running “watch” task Waiting

问题

I have a problem with grunt-watch. When I use "grunt" in terminal outputs "Running "watch" task Waiting..."

krp-arina@krparina-Lenovo-G555:~/server$ grunt
Running "watch" task
Waiting...
krp-arina@krparina-Lenovo-G555:~/server$ grunt -v

But this does nothing, it just ends.

I want to compile less at each change. Here's my Gruntfile.js

module.exports = function(grunt) {
  require('load-grunt-tasks')(grunt);
  // Project configuration.

  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    less: {
      dist:{
        files: {
          'pd_wp/www/wp-content/themes/anarchy/css/commons.css':'pd_wp/www/wp-content/themes/anarchy/css/commons.less'
        },
        options: {
          compress: true,
          cleancss: false
        }
      }
    },
    watch: {
      options: {
        less: {
          files: ['pd_wp/www/wp-content/themes/anarchy/css/*.less'],
          tasks: ['less'],
          // options: {
          //   spawn: false
          // }
        }
      }
    }
  });


  // Default task(s).
  grunt.registerTask('w', ['watch']);
  grunt.registerTask('default', ['watch']);

};

I use grunt-cli v0.1.13 grunt v0.4.5 grunt-contrib-less v1.0.0 grunt-contrib-watch v0.6.1 load-grunt-tasks v3.1.0

nodejs v0.12.1

Somebody tell me what am I doing wrong

回答1:

I'm pretty sure your issue here is the order of your json config. I may be wrong though. The docs list watch: { taskName: { options: {} } }

and you have

watch: { options: { taskName: {} } }

have you tried this:

watch: {
      less: {
          files: ['pd_wp/www/wp-content/themes/anarchy/css/*.less'],
          tasks: ['less']
      }
  }
