gulp将多个JS合并为一个

Question

我有一个任务gulp dev，应该将JS文件数组合并到dist / js中，但是我似乎无法得到gulp命令来创建文件dist / js，有人可以看到我去了哪里现在9个小时错了。 谢谢

原始文件

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...

任务/ js

    var gulp           = require("gulp"),
    utils          = require("./utils"),
    config         = utils.loadConfig(),

    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!

        ],

        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"
]);
