InversifyJS:注入(inject)扩展不可注入(inject)外部模块的类

Question

在与 Inversify 相关的实现方面需要帮助。我正在创建一个从节点扩展 EventEmitter 的类。当我尝试使用 inversify 时，它说 EventEmitter 不可注入(inject)。以下是示例代码

//界面

export interface ISubscriber {
Connect(callback: Function);
on(event: string, listener: Function): this;
emit(event: string, ...args: any[]): boolean;
}

//类(class)

import {EventEmitter} from 'events';


@injectable()
class Subscriber extends EventEmitter implements ISubscriber {
logProvider: SCLogging.ILogger;
public constructor(
    @inject(TYPES.ILogger) logProvider: SCLogging.ILogger,
    @inject(TYPES.IConfig) config: IConfig
) {
    super();
    //Some Implementation
}

public Connect(callback) {
//Some Implementation
}

public on(event: string, listener: Function): this {
    super.on(event, listener);
    return this;
}

public emit(event: string, ...args: any[]): boolean {
    return super.emit(event, ...args);
}
}
export { ISubscriber, Subscriber }

//定义绑定(bind)

kernel.bind<SCLogging.ILogger>(TYPES.ILogger).to(Logger);
kernel.bind<IConfig>(TYPES.IConfig).to(Config);
kernel.bind<ISubscriber>(TYPES.ISubscriber).to(Subscriber);

我收到错误

Error: Missing required @injectable annotation in: EventEmitter.

已经有一个非常相似的问题 answered on the InversifyJS issues on Github :

You can invoke the decorator using the decorate function:

import { decorate, injectable } from "inversify";
decorate(injectable(), ClassName)
