开发时关闭Grunt Concat

Question

我目前遇到的问题是Grunt将所有内容汇总在一起所以如果有一个.js错误那么它只是在连接文件中的一行显示它而不是我真正应该看的地方是否有办法关闭concat ，uglify或任何我需要阻止这种情况发生...在“开发者模式”中标记它的方式真的很酷然后去生产它可以自动回到concat，uglify，但我我满足于在我工作时将其关闭然后恢复更改。

GruntFile：

/*global module:false*/
module.exports = function (grunt) {

        useminPrepare: 'grunt-usemin'

    // Project configuration.
    grunt.initConfig({
        // Metadata.
        pkg: grunt.file.readJSON('package.json'),
        banner: '/*! <%= pkg.title || pkg.name %> - v<%= pkg.version %> - ' +
        '<%= grunt.template.today("yyyy-mm-dd") %> */\n',

创建如下不同的配置：

grunt.registerTask('dev', [
// List all tasks for dev
]);

grunt.registerTask('prod', [
// List all tasks for production
]);

执行：grunt dev
