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 Initializing Command-line options: --verbose  Reading "Gruntfile.js" Gruntfile...OK  Registering Gruntfile tasks.

Running tasks: default  Running "default" task  Running "watch" task Waiting... Verifying property watch exists in config...OK 

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']       }   } 

grunt-contrib-watch docs
