Angular 2 Material 2 Slide Toggle Doesn't Seem to be working in Alpha 7 Error: Cannot find name 'HammerInput'

Question

我刚升级到 Alpha 7，升级后 Slide Toggle 似乎坏了。

当我在 Visual Studio 2015 年编译我的项目时，我收到以下错误：

Error       Build:Cannot find name 'HammerInput'.   node_modules\@angular2-material\slide-toggle\slide-toggle.d.ts  67  

Error   TS2304  Cannot find name 'HammerInput'. TypeScript Virtual Projects node_modules\@angular2-material\slide-toggle\slide-toggle.d.ts  67

显然是下面这行导致了 slide-toggle.d.ts 中的问题：

_onDrag(event: HammerInput): void;

Answer 1

谢谢大家通过命令安装打字：

npm install --save hammerjs @types/hammerjs

然后在主文件中导入它解决了问题。:

/// <reference path="../typings/globals/hammerjs/index.d.ts" />
