Visual studio 2015 在VS2015任务运行器资源管理器中运行gulp文件失败

我正在跟随Chris Sakell的教程，以期在AngularJs 2上进行水疗

按照指示，我在根目录中创建了gulp文件-gulp.js，在webroot目录中创建了tsconfig.json文件

我安装了npm和gulp，因为这是初始过程的一部分

我的想法是在wwwroot文件夹下创建和填充目录，包括“lib”和“app”

我尝试在VS2015中使用Task Runner Explorer来运行此任务，特别是单击左侧的“build spa”，我得到：

    :\Users\simon\SPA\CHASAKELL-SCRATCH\PhotoGallery\src\PhotoGallery\Gulpfile.js" build-spa
[14:27:12] Using gulpfile ~\SPA\CHASAKELL-SCRATCH\PhotoGallery\src\PhotoGallery\Gulpfile.js
[14:27:12] Starting 'setup-vendors'...
[14:27:12] Starting 'compile-typescript'...
[14:27:12] Finished 'compile-typescript' after 20 ms
Process terminated with code 0.

wwroot下未创建任何文件，并且似乎未创建任何内容。这些文件有什么问题？或者，在VS2015中成功运行gulp.js文件的过程中，是否有我没有做的事情

编辑：好的，所以我从命令窗口运行了“gulp build spa”，它成功了。。。那么为什么它在VS2015中不起作用呢

tsconfig.json文件如下所示：

{
"compilerOptions": {
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "module": "commonjs",
    "moduleResolution": "node",
    "noEmitOnError": false,
    "noImplicitAny": false,
    "removeComments": false,
    "sourceMap": true,
    "target": "es5"
},
"exclude": [
    "node_modules/**/*.d.ts",
    "wwwroot",
    "typings/main",
    "typings/main.d.ts"
]
}

gulp.js文件是：

        var gulp = require('gulp'),
        ts = require('gulp-typescript'),
        merge = require('merge'),
        fs = require("fs"),
        del = require('del'),
        path = require('path');

    eval("var project = " + fs.readFileSync("./project.json"));
    var lib = "./" + project.webroot + "/lib/";

    var paths = {
        npm: './node_modules/',
        tsSource: './wwwroot/app/**/*.ts',
        tsOutput: lib + 'spa/',

        jsVendors: lib + 'js',
