angular2 升级到 rc1 "Ruler, Rectangle and Browser" 丢失
angular2 upgrade to rc1 "Ruler, Rectangle and Browser" are missing
从 beta 升级到 RC1 之后，typescript 编译器在这两行上抛出错误：
import {Ruler, Rectangle} from "angular2/src/platform/browser/ruler";
import * as browser from "angular2/platform/browser";
它们去了哪里？是被替换到其他包中还是被迁移了？
RC1 将导入更改为在@angular 范围内，因此您需要导入才能使用 @angular/platform-browser:
