如何使用map函数为每个循环生成基于Object.keys的动态任务
首先，我只想定义常量 像

const js = pkg.jscripts,

其变量如

importScss: {
    filetype: {
      ext: "/**/*.scss",},bootstrap: {
      filename: "bootstrap",filepath: "node_modules/bootstrap-sass/assets/stylesheets/bootstrap",dest: pkg.name + "/css/bootstrap"
    },bootstrapSelect: {
      filename: "bootstrap-select",filepath: "node_modules/bootstrap-select/sass",dest: pkg.name + "/css/bootstrap-select"
    },lightgallery: {
      filename: "lightgallery",filepath: "node_modules/lightgallery/src/sass",dest: pkg.name + "/css/lightgallery"
    },owlCarousel: {
      filename: "owl.carousel",filepath: "node_modules/owl.carousel/src/scss",dest: pkg.name + "/css/owl.carousel"
    },fontawesome: {
      filename: "fontawesome",filepath: "node_modules/@fortawesome/fontawesome-free/scss/",dest: pkg.name + "/css/fontawesome"
    }
  },

我尝试正确执行任务

var jsTasks = Object.keys(js);
jsTasks.forEach(function (libName) {
    //console.log(libName);
    gulp.task(libName,function () {
        //console.log(js[libName].filepath);
        return gulp.src(js[libName].filepath)
            //.pipe(plugins.jshint()) // if you want it
            //.pipe(plugins.uglify()) // if you like it
            .pipe(plugins.concat(js[libName].filename)) // .min.js if you Uglified it
            .pipe(header(jsbanner,{ pkg: pkg }))
            .pipe(header(banner,{ pkg: pkg }))
            .pipe(gulp.dest(js[libName].dest));
    });
});

gulp.task('js',gulp.parallel(
        jsTasks.map(
            function (jscript) {
                console.log(jscript);
                return jscript;
            })
        //console.log(jsTasks.map(function (jscript) { return jscript; }))
    )
);

它正常工作

但是我想喜欢这样的基于动态任务的Object。带有地图的每个循环的键

function aruntask(keys) {
    //console.log(keys)
    var myobj = Object.keys(keys);
    //console.log(mytask);
    myobj.forEach(function (libName) {
        //console.log(keys[libName].filepath);
        gulp.task(libName,function () {
            console.log(keys[libName].filepath);
            return gulp.src(keys[libName].filepath)
                //.pipe(plugins.jshint()) // if you want it
                //.pipe(plugins.uglify()) // if you like it
                .pipe(plugins.concat(keys[libName].filename)) // .min.js if you Uglified it
                .pipe(header(jsbanner,{ pkg: pkg }))
                .pipe(gulp.dest(keys[libName].dest));
        });
    });


}

gulp.task('js',gulp.parallel(
        jsTasks.map(function (jscript) { return jscript; })
    )
);
