相关疑难解决方法(0)

我对Angular2和打字稿都比较新.由于打字稿是javascript的超集,我希望函数console.log能够工作.console.log在.ts组件类之外的文件中完美地工作,但是不能像我期望的那样在组件类中工作.

// main.ts

import { Component } from '@angular/core';
console.log("Hello1"); //1. This works perfectly

@Component({..)
export class App {
 s: string = "Hello2";
 // console.log(s); //2. This gives compilation error (when uncommented)
 // Error: Function implementation is missing or not immediately following the declaration.
}

有什么我想念的吗？
