Question

我遇到了grunt-watch的问题。当我使用＆＃34; grunt＆＃34;在终端输出＆＃34;跑步＆＃34;观看＆＃34;任务等待......＆＃34;

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.

+ default, w

No tasks specified, running default tasks.
Running tasks: default

Running "default" task

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

但这没有任何作用，只是结束了。

我想在每次更改时编译得更少。这是我的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']);

};

我用 grunt-cli v0.1.13 咕噜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

有人告诉我，我做错了什么

Answer 1

我很确定你的问题是json配置的顺序。我可能错了。文档列表 watch: { taskName: { options: {} } }

你有

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

你尝试过这个：

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

您必须指定一个任务例如：

咕post的帖子

如果不确定，请调用grunt -help：

grunt -help
Grunt: The JavaScript Task Runner (v0.4.5)

Usage
 grunt [options] [task [task ...]]

Options
    --help, -h  Display this help text.                                        
        --base  Specify an alternate base path. By default, all file paths are 
                relative to the Gruntfile. (grunt.file.setBase) *              
    --no-color  Disable colored output.                                        
   --gruntfile  Specify an alternate Gruntfile. By default, grunt looks in the 
                current or parent directories for the nearest Gruntfile.js or  
                Gruntfile.coffee file.                                         
   --debug, -d  Enable debugging mode for tasks that support it.               
       --stack  Print a stack trace when exiting with a warning or fatal error.
   --force, -f  A way to force your way past warnings. Want a suggestion? Don't
                use this option, fix your code.                                
       --tasks  Additional directory paths to scan for task and "extra" files. 
                (grunt.loadTasks) *                                            
         --npm  Npm-installed grunt plugins to scan for task and "extra" files.
                (grunt.loadNpmTasks) *                                         
    --no-write  Disable writing files (dry run).                               
 --verbose, -v  Verbose mode. A lot more information output.                   
 --version, -V  Print the grunt version. Combine with --verbose for more info. 
  --completion  Output shell auto-completion rules. See the grunt-cli          
                documentation for more information.                            

Options marked with * have methods exposed via the grunt API and should instead
be specified inside the Gruntfile wherever possible.

Available tasks
          sass  Compile Sass to CSS *                                          
       postcss  Process CSS files. *                                           
         watch  Run predefined tasks whenever watched files change.            
       default  Alias for "watch" task.                                        

Tasks run in the order specified. Arguments may be passed to tasks that accept
them by using colons, like "lint:files". Tasks marked with * are "multi tasks"
and will iterate over all sub-targets if no argument is specified.

The list of available tasks may change based on tasks directories or grunt
plugins specified in the Gruntfile or via command-line options.

这是postcss的运行时示例

francoisgravel@LMSD-FGRAVEL vistage-mv3 % grunt postcss
Running "postcss:dist" (postcss) task
Browserslist: caniuse-lite is outdated. Please run next command `npm update`
>> 1 processed stylesheet created.

Done, without errors.
