Grunt 指南针开发和产品

Question

我对 GruntJS + SASS Compass 有疑问。我已经设置了 dev 和 prod 配置。 对于dev，css 有outputStyle: 'expanded'，对于prod，有outputStyle: 'compressed'。当我在做prod 时 - 它就像一个魅力。在控制台中我看到了

Running "compass:dist" (compass) task
overwrite css/screen.css (0.392s)
Compilation took 0.4s

css 压缩到应有的样子。

但是当我在做dev它时，控制台什么也没有显示

Running "compass:dev" (compass) task

Running "autoprefixer:dist" (autoprefixer) task

而且 css 仍然被压缩。

这是我的 Gruntfile.js 配置：

module.exports = function(grunt) {
grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),

    compass: {
        dev: {
            options: {
                sassDir: 'sass',
                cssDir: 'css',
                imagesDir: 'images',
                fontsDir: 'fonts',
                relativeAssets: true,
                boring: true,
                outputStyle: 'expanded',
                environment: 'development',
                raw: 'preferred_syntax = :sass\n'
            }
        },
        dist: {
            options: {
                sassDir: 'sass',
                cssDir: 'css',
                imagesDir: 'images',
                fontsDir: 'fonts',
                relativeAssets: true,
                boring: true,
                force: true,
                bundleExec: true,
                outputStyle: 'compressed',
                environment: 'production',
                raw: 'preferred_syntax = :sass\n'
            }
        }
    },

    autoprefixer: {
        dist:{
            files:{
                'css/screen.css':'css/screen.css'
            }
        }
    },

    concat: {

            ],
            dest: 'js/companyname/main.js'
        }
    },

    jshint: {
        all: ['Gruntfile.js'],
        beforeconcat: [
            'js/src/companyname/app.js',
            'js/src/companyname/bar.js'
        ]
    },

        prod: {

                dest: 'js'
            }]
        }
    },

    copy: {
        main: {

grunt.registerTask('prod', [

我做错了什么？

你可以制作两个不同的指南针开发者。

compass: {
   dev: {
     ...
     force: true
     ...
   },
   devWatch: {
   ... ur original ... 
   }
}

watch(compass: {tasks: ['compass:devWatch', ...]})

grunt.registerTask('watch', [
   'compass:dev',
   'watch'
]);

grunt.registerTask('dev', [
   'compass:dev'
]);
