javascript - Angular 无法绑定(bind)到 'dragula'，因为它不是 'ul' 的已知属性

Question

我一直在尝试在 Angular 2 应用程序中使用 Dragula，但无法使其工作。

这是我在 app.module.ts 中放入的内容

import { DragulaModule, DragulaService } from 'ng2-dragula/ng2-dragula';

@NgModule({
    imports: [
        // ...
        DragulaModule
    ],
    declarations: [ ... ],
    providers: [
        DragulaService
    ],
    bootstrap: [ ... ]
})
export class AppModule {}

在我使用 Dragula 的组件中，我以这种方式导入它:

import { DragulaModule, DragulaService } from 'ng2-dragula/ng2-dragula';

export class MyComponent implements OnInit, OnDestroy {

    constructor(private dragulaService: DragulaService) {}

这是我尝试在 View 中构建的简单内容，但它不起作用:

<ul [dragula]="'one'" [dragulaModel]="items">
    <li *ngFor="let item of items">{{item}}</li>
</ul>

我尝试从“ng2-dragula”、“ng2-dragula/ng2-dragula”以及我在网上找到的解决方案中的其他一些导入它们，但到目前为止还没有运气。当我尝试 console.log DragulaModule 和 DragulaService 以查看是否找到它们时，DragularService 返回一个包含内容的函数，而 DragulaModule 返回一个空函数。

这是我在控制台中收到的错误:

Answer 1

import {DragulaModule} from "ng2-dragula";

@NgModule({
imports: [DragulaModule],
declarations: []
});

这个修复将会起作用...
