angular2快速入门找不到名称“模块”

Question

I'm following Tour of Heroes tutorial for building my first app.I have written a component file threads.component.ts as follows:

@Component({
    moduleId: module.id,
    selector: 'Threads',
    templateUrl: './threads.component.html',
    styleUrls: ['./threads.component.css']
})

but I'm getting the error 'Cannot find name module', what can I do to fix this problem?

Answer 1

That is a typescript error. You can add the types for node and it gets resolved:

 npm install -D @types/node

And in your tsconfig:

//tsconfig.json
{
  ...
  "compilerOptions": {
      "types" : ["node"]
  }
 ... 
}

Simpler version if you don't want to install types:

add this at top of your component:

declare var module: {
  id: string;
}
