将多个JS合并为一个

我有任务 gulp dev 这应该会将一组JS文件合并到dist/JS中的一个文件中,但是我似乎无法获得gulp命令来创建文件dist/JS,有人能看到我在这9个小时里哪里出错了。 谢谢

大口锉

gulp.task("dev", function () {

    // set the dev config (cache in utils.js)
    utils.setConfig({
        env: "dev",
        watch: true,
        notify: true,
        tasks: ["js", "css", "copy", "bower", "svg-sprite"]
    });

    // build with this config
    utils.build();

});

然后。。。

    var gulp           = require("gulp"),
    utils          = require("./utils"),
    config         = utils.loadConfig(),
    gulpif         = require("gulp-if"),
    fs             = require("fs"),
    uglify         = require("gulp-uglify"),
    sourcemaps     = require("gulp-sourcemaps"),
    browserify     = require("browserify"),
    shim           = require("browserify-shim"),
    through2       = require("through2"),
    babelify       = require("babelify"),
    minify         = require('gulp-minify'),
    replaceName    = require('gulp-replace-name');


// dev/default settings
utils.setTaskConfig("js", {

    default: {

        // Pass array instead of single file!
        src: [
            config.root + "/js/index.js",
            config.root + "/js/owlCarousel.js",
            config.root + "/js/search/search.js",

            // Angular 1.x doesn't play well with CommonJS modules :(
            config.root + "/js/search/angular-1.5.1.min.js",
            config.root + "/js/search/angular-animate-1.5.1.min.js",
            config.root + "/js/search/angular-sanitize-1.5.1.min.js"
        ],

        dest: config.dest + "/js",

        // js uglify options, to skip, set value to false or omit entirely
        // otherwise, pass options object (can be empty {})
        uglify: false,

        // browserify options
        browserify: {
            debug: true // enable sourcemaps
        }
    },

    prod: {

        browserify: {},

        // uglify javascript for production
        uglify: {}
    }
});


// register the watch
utils.registerWatcher("js", [
    config.root + "/js/**/*.js",
    config.root + "/js/**/*.jsx"
]);
