在搜索了这个问题之后，根据angular-cli票证，它似乎与angular-cli有关。票证上说从beta15开始已经修复了，因此我添加了最新的angular-cli版本beta.19-3。但是，gulp仍然显示此错误，我不确定是否需要以不同的方式引用angular-cli以使其工作。我使用gp_uglify和gp_uglify_harmony尝试了两种不同的方法。但是我仍然有同样的错误。

gulpfile.js(任务)

gulp.task('app', ['app_clean'], function (cb) {
    pump([
        gulp.src(srcPaths.app),
        gp_sourcemaps.init(),
        gp_typescript(require('./tsconfig.json').compilerOptions),
        //gp_uglify({ mangle: false }),
        minifier(options, gp_uglify_harmony),
        gp_sourcemaps.write('/'),
        gulp.dest(destPaths.app)
    ],
    cb
    );
});

似乎有些选项缺失，我也发现这些帖子，参考一个懒惰的选项，但我被困在我应该使用它的方式$ Is未定义脚本Gulp任务和Gulp -load-plugins不加载插件

编辑。添加最后两个链接

如果有人有类似的问题，最好的方法是使用日志记录，这通常会引导到问题的根源

// Compile, minify and create sourcemaps all TypeScript files 
// and place them to wwwroot/app, together with their js.map files.
gulp.task('app', ['app_clean'], function (cb) {
    pump([
        gulp.src(srcPaths.app),
        gp_sourcemaps.init(),
        gp_typescript(require('./tsconfig.json').compilerOptions),
        gp_uglify({mangle:false}).on('error', gutil.log),
        gp_sourcemaps.write('/'),
        gulp.dest(destPaths.app)
    ],
    cb
    );
});
