Angular 2 Universal Quickstart - 要求'ProvideRouter'无法正常工作

Question

我正在尝试使用quickstart

为Angular Universal设置项目

但是进展不顺利，尝试安装打字时出现了很多错误：

Benjamins-MBP:vepo Ben$ sudo typings install node express body-parser serve-static express-serve-static-core mime --ambient
typings ERR! deprecated The "ambient" flag is deprecated. Please use "global" instead
Benjamins-MBP:vepo Ben$ sudo typings install node express body-parser serve-static express-serve-static-core mime --global

typings ERR! message However, we found "express-serve-static-core" for 1 other source: "dt"

然后我添加了server.js文件并尝试使用node server.js运行它：

我问question about it and got an answer so accepted it，但无法成功实现答案：

require('angular2-universal-polyfills');
require ('path');
require ('express');

// Angular 2 Universal
require ('@angular/router/provideRouter');
require ('@angular/core/enableProdMode');
require ('angular2-universal/*');

// replace this line with your Angular 2 root component
require ('./app/AppModule');
require ('./app/app.routes')

得到了这个错误：

Benjamins-MBP:vepo Ben$ node server.js
module.js:471
    throw err;
    ^

Error: Cannot find module '@angular/router/provideRouter'

因为该级别没有provideRouter。如何使用require导入它？

这是我的@angular文件夹：

如何编辑我的require语句以正确导入所需的模块？

我认为您应该使用provideRoutes代替provideRouter。
