Typescript: “typeof FooBar”类型的参数不可分配给“new () => FooBarInterface”类型的参数

大家好，我正在为名为InversifyJS 的TypeScript 应用程序开发 IoC 容器。 我实现了一个名为TypeBinding<TServiceType> ，它用于定义service type （接口）和implementation type （类）之间的绑定。 类代码如下：

// Defines allowed scope modes
enum TypeBindingScopeEnum {
  Transient,
  Singleton
}

class TypeBinding<TServiceType> {

    // The runtime identifier used because at runtime
    // we don't have interfaces
    public runtimeIdentifier : string;

    // The constructor of a class that must implement TServiceType
    public implementationType : { new(): TServiceType ;};

    // Cache used to allow singleton scope
    public cache : TServiceType;

    // The scope mode to be used
    public scope : TypeBindingScopeEnum;

    constructor(
      runtimeIdentifier : string,
      implementationType : { new(): TServiceType ;},
      scopeType? : TypeBindingScopeEnum) {

      this.runtimeIdentifier = runtimeIdentifier;
      this.implementationType = implementationType;
      this.cache = null;
      if(typeof scopeType === "undefined") {
        // Default scope is Transient
        this.scope = TypeBindingScopeEnum.Transient;
      }
      else {
        if(TypeBindingScopeEnum[scopeType]) {
            this.scope = scopeType;
        }
        else {
          var msg = `Invalid scope type ${scopeType}`;
          throw new Error(msg);
        }
      }
    }
}

我定义了一些实体来测试TypeBinding<TServiceType>类：

interface FooInterface {
  logFoo() : void;
}

interface BarInterface {
  logBar() : void;
}

interface FooBarInterface {
  logFooBar() : void;
}

// Notice default constructor
class Foo implements FooInterface {
  public logFoo(){ 
    console.log("foo"); 
  }
}

// Notice default constructor
class Bar implements BarInterface {
  public logBar(){ 
    console.log("bar"); 
  }
}

// Notice dependencies on FooInterface and  BarInterface on constructor
class FooBar implements FooBarInterface {
  public foo : FooInterface;
  public bar : BarInterface;
  public logFooBar(){ 
    console.log("foobar"); 
  }
  constructor(FooInterface : FooInterface, BarInterface : BarInterface) {
    this.foo = FooInterface;
    this.bar = BarInterface;
  }
}

我可以使用TypeBinding<TServiceType>类，而Foo和Bar类没有问题

var fooBinding = new TypeBinding<FooInterface>("FooInterface", Foo);
var barBinding = new TypeBinding<BarInterface>("BarInterface", Bar);

当我尝试使用{ new(): TServiceType ;}并且实现TServiceType的类的构造函数不是无参数时，我的问题就出现了。

“typeof FooBar”类型的参数不可分配给“new () => FooBarInterface”类型的参数。

var fooBarBinding = new TypeBinding<FooBarInterface>("FooBarInterface", FooBar);

如何解决这个问题？

谢谢 ：）
