兼容的类型签名出现问题

Question

我正在尝试用打字稿写一个通用的链表，但是兼容的电话签名有一些问题。我刚接触打字稿，我不知道自己做错了什么。

我正在使用-target es2017选项编译以下代码。

class Node<T>
{
    private _data : T;
    private _prev : Node<T> | null;
    private _next : Node<T> | null;

    public constructor(data : T,prev = null,next = null)
    {
        this._data = data;
        this._prev = prev;
        this._next = next;
    }

    public get data() : T
    {
        return this._data;
    }

    public get prev() : Node<T> | null
    {
        return this._prev;
    }

    public get next() : Node<T> | null
    {
        return this._next;
    }

    public set setData(data : T)
    {
        this._data = data;
    }

    public set setPrev(node : Node<T> | null)
    {
        this._prev = node;
    }

    public set setNext (node : Node<T> | null)
    {
        this._next = node;
    }
}

export default class LinkedList<T>
{
    private front : Node<T> | null;
    private back : Node<T> | null;

    public constructor()
    {
        this.front = null;
        this.back = null;
    }

    push(data : T) : void
    {
        let newNode = new Node<T>(data);
        if(this.back)
        {
            (this.back)!.setNext(newNode);
            newNode.setPrev(this.back!);
        }
        else
        {
            this.front = newNode;
            this.back = newNode;
        }
    }
}

“ Cannot invoke an expression whose type lacks a call signature. Type 'Node <T>' has no compatible call signatures.” 这是我在编译时遇到的错误。
