我在Gruntfile.js中进行了此设置

module.exports = function(grunt) {
    grunt.initConfig({
        less: {
            development: {
                options: {
                    compress: false,
                    yuicompress: false,
                    optimization: 0
                },
                files: {
                    // target.css file: source.less file
                    "assets/css/main.css": "assets/css/main.less"
                },
            } 
        },
        watch: {

            styles: {
                // Which files to watch (all .less files recursively in the less directory)
                files: ['assets/css/*.less', 'assets/less/*.less'],
                tasks: ['less'],
            },
            // Live reload CSS
            css: {
                files: ['assets/css/*.css'],
                options: {
                    nospawn: true,
                    interrupt: false,
                    livereload: true,
                },
            },
        },
    });
    // Watch
    grunt.loadNpmTasks('grunt-contrib-watch');
    // Less Complile …
