Angular2 V3路由器

Question

I am trying to the new v3 router. I was able to update my package json to point to the alpha and install it. I am getting this error everywhere...

node_modules/@angular/router/router.d.ts(80,59): error TS2304: Cannot find name 'Promise'.

Is there something else I need to upgrade. I remember reading something somewhere about update typings. I tried npm install typings -g with no such luck.

Any help would be greatly appreciated!

Make sure the typings are included in TypeScript compiler configuration. You can include them in few ways:

// tsconfig.json
{
  "files": [
    ...,
    "typings.d.ts",
  ]
}

or include typings.d.ts content in one of the first files compiler looks for (like, main.js or bootstrap.js ):

/// <reference path="../typings/browser.d.ts" />

This points to the typings/ folder and a file that has all definitions you installed using typings install whatever command, for example this is the file AngularCLI generates:

// browser.d.ts
/// <reference path="browser/ambient/angular-protractor/index.d.ts" />
/// <reference path="browser/ambient/es6-shim/index.d.ts" />
/// <reference path="browser/ambient/jasmine/index.d.ts" />
/// <reference path="browser/ambient/node/index.d.ts" />
/// <reference path="browser/ambient/selenium-webdriver/index.d.ts" />

TS2304: Cannot find name 'Promise'

This error tells you that compiler cannot locate definitions for Promise, which are located in es6-shim/index.d.ts .
