即使被引用，Typescript也找不到名称

Question

I have an angular project I'm writing in typescript. This worked well for me under VS, and now I'm trying the same with Node.JS under webstorm.

I have a progressor class, in a progressor.ts file:

export class Progressor{
    public tasks: any;

    constructor(){
        this.tasks = {};
    }
    ...
}

and I have my main controller, which uses this class:

/// <reference path="../progressor.ts" />

declare var angular: any; // I'm trying to eliminate these...
declare var Papa: any;
declare var $: any;

class MainController{
    constructor($scope: any){
        $scope.progressor = null;
        $scope.filesDropped = function(files, rejectedFiles){
            if(!files || !files.length)
                return;

            $scope.progressor = new Progressor();
            // ...
        }
    };
}

Note that this is not Node.JS code - it is simply part of a Node.JS project.

The relative reference path is correct. When I try to compile it using:

tsc mainController.ts --module amd --target es5

I get an error: Cannot find name Progressor.

I don't understand what's the problem... I've been having nothing but trouble with my Node.JS project so far, and I'm considering giving up on TS altogether for this project. First of all - can anyone tell me why it won't compile? Note that I want each TS file to be compiled separately, so I can debug them comfortably via Chrome.

Answer 1

If you've export ed something, you need to import it in order to consume it, not <reference ... it.

Replace the <reference comment with import prog = require('./progressor'); , then you can use eg new prog.Progressor() .

You might consider using export = Progressor so that the exported object from the other file is the class itself instead of a container.

Answer 2

After a while more of searching, I stumbled upon this: TypeScript Modules . After consulting it, I tried placing both my classes inside module{ } blocks, which solved the problem. I'm still slightly confused as to why the language would require me to use modules for multi-file usage... but for now it will do.
