在打字稿中引用外部模块-错误TS2304：找不到名称“通用”

Question

I prepared these two files:

1st one is general.d.ts file

interface IgeneralStatic {
    General: {
        Langs: any;
    };
}

declare var general: IgeneralStatic;

declare module 'general' {
    export = general;
}

2nd one is just something.ts file where i'm trying to import a file alias:

/// <reference path="general.d.ts" />

import general = require('general');

export class SpecificLangs extends general.General.Langs
  ...
}

When i trying to compile it i'm getting this error:

error TS2304: Cannot find name 'general'

The reason of this that I don't know where is my module and I can't import it for typescript usage. It is resolved on requirejs side as package. So there is no way to reference, using import, original general.ts file.

Answer 1

Your definition works, in that you can import it...

For example, I can reference Langs like so:

var x = general.General.Langs;

However, you haven't declared that Langs is a class, so you can't extend it as if it were one.

If it is implemented in a way that allows you to extend it, declaring it as a class will allow it to be used as a base class (simplified example to demonstrate that using a class works):

declare module 'general' {
    export module General {
        export class Langs {


        }
    }
}
