我正在尝试一个示例 angular2 应用程序：
https://github.com/thelgevold/angular-2-samples
文件夹结构：
当我运行时：
\angular-2-samples>tsc -m commonjs -t es5 --emitDecoratorMetadata --experimentalDecorators --jsx react app.ts
一切都很好，但是当我跑步时
\application\app\typescript>tsc -m commonjs -t es5 --emitDecoratorMetadata --expe
rimentalDecorators --jsx react app.ts
app.ts(1,30): error TS2307: Cannot find module 'angular2/http'.
