我已按照此处的说明操作：https://github.com/valor-software/ng2-dragula/wiki#5-min-quickstart以及此处：https://www.npmjs.com/package/ng2-dragula
Angular-quickstart正在按照以下方式运作：
git clone https://github.com/angular/quickstart angular2-dragula-test
npm install
npm start
“My First Angular App”（在浏览器中弹出 - 所以一切正常）
我通过以下方式安装dragula：
npm install ng2-dragula dragula --save
我用valor-software ng2-dragula wiki（第一个链接）的确切内容替换了quickstart文件。
如果有人可以提供任何建议（关于未列出的关键步骤）或简单的健全检查，我们将不胜感激。

这些是使用angular-quickstart设置ng2-dragula基本测试应用程序的完整说明（参见底部＆＃34;使用Angular-CLI更新＆＃34;如果使用Angular-CLI）：
设置一个新的angular-quickstart项目：
mkdir angular2-dragula-test
git clone https://github.com/angular/quickstart angular2-dragula-test
cd angular2-dragula-test
npm install
npm start
如果一切顺利，你应该有一个网页说明＆＃34; My First Angular 2 App＆＃34;，基本的angular2-quickstart正在运行，我们现在添加了dragula。
npm install ng2-dragula dragula
在 index.html 中，我们通过添加以下行添加dragula.css：
<link rel="stylesheet" href="node_modules/dragula/dist/dragula.css">
这是我的完整 index.html 供参考：

systemjs.config.js （查找两个评论阅读＆＃34; // ***以下是dragula ******的要求**************＆＃34;如果你只是想添加相关的行）：
/**

*/
(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
app: 'app',

}
});
})(this);
在 app.module.ts 中导入DragulaModule：
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { DragulaModule } from 'ng2-dragula/ng2-dragula'; //THIS IS NEW***
@NgModule({
imports: [ BrowserModule, DragulaModule ], //ADDED DragulaModule***
declarations: [ AppComponent],
bootstrap: [ AppComponent ]
})
export class AppModule { }
将app.component.ts替换为以下内容：
import { Component } from '@angular/core';
import { DragulaService } from 'ng2-dragula/ng2-dragula';
@Component({
selector: 'my-app',
template: `<h1>My First Angular 2 App</h1>
<div>
<div class='wrapper'>
<div class='container' [dragula]='"first-bag"'>
<div>Drag/drop item 1</div>
</div>
<div class='container' [dragula]='"first-bag"'>
<div>Drag/drop item 2</div>
</div>
</div>
</div>
`,
viewProviders: [DragulaService],
styles: [`
.wrapper {
display: table;
}
.container {
display: table-cell;
background-color: rgba(255, 255, 255, 0.2);
width: 50%;
}
.container:nth-child(odd) {
background-color: rgba(0, 0, 0, 0.2);
}
.container div,
.gu-mirror {
margin: 10px;
padding: 10px;
background-color: rgba(0, 0, 0, 0.2);
transition: opacity 0.4s ease-in-out;
}
.container div {
cursor: move;
cursor: grab;
cursor: -moz-grab;
cursor: -webkit-grab;
}
.gu-mirror {
cursor: grabbing;
cursor: -moz-grabbing;
cursor: -webkit-grabbing;
}
`]
})
export class AppComponent { }
使用Angular-CLI进行更新
幸运的是，指令比上面要求的更容易：
首先设置一个新项目，然后添加Dragula：
ng new ngcli-dragula
cd ngcli-dragula
npm install ng2-dragula dragula
如果您收到错误，例如以下：
npm install ng2-dragula dragula
ngcli-dragula@0.0.0 /home/quaterion/Development/ngcli-dragula
├── UNMET PEER DEPENDENCY @angular/compiler@4.0.3
├── UNMET PEER DEPENDENCY @angular/forms@4.0.3
├─┬ dragula@3.7.2
│ ├─┬ contra@1.9.4
│ │ ├── atoa@1.0.0
│ │ └── ticky@1.0.1
│ └─┬ crossvent@1.5.4
│ └── custom-event@1.0.0
└── ng2-dragula@1.3.1
然后你需要升级angular-cli，也许是升级npm的好主意：
npm install npm -g
npm install -g @angular/cli
将以下行添加到index.html：
<link rel="stylesheet" href="node_modules/dragula/dist/dragula.css">
在app.module.ts中导入DragulaModule（参见两条评论＆＃34; // NEW＆＃34;）：
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { AppComponent } from './app.component';
import { DragulaModule } from 'ng2-dragula/ng2-dragula'; //NEW
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
FormsModule,
HttpModule,
DragulaModule//NEW
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
在app.component.ts中导入DragulaService（参见两条评论＆＃34; // NEW＆＃34;）：
import { Component } from '@angular/core';
import { DragulaService } from 'ng2-dragula/ng2-dragula';//NEW
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css'],
viewProviders: [DragulaService]//NEW
})
export class AppComponent {
title = 'app works!';
}
更新html（app.component.html），以便有一个有效的例子：
<h1>
{{title}}
</h1>
<div>
<div class='wrapper'>
<div class='container' [dragula]='"first-bag"'>
<div>Drag/drop item 1</div>
</div>
<div class='container' [dragula]='"first-bag"'>
<div>Drag/drop item 2</div>
</div>
</div>
</div>
现在有一个工作示例，这个可选的CSS块将使示例看起来更好（app.component.css）：
.wrapper {
display: table;
}
.container {
display: table-cell;
background-color: rgba(255, 255, 255, 0.2);
width: 50%;
}
.container:nth-child(odd) {
background-color: rgba(0, 0, 0, 0.2);
}
.container div,
.gu-mirror {
margin: 10px;
padding: 10px;
background-color: rgba(0, 0, 0, 0.2);
transition: opacity 0.4s ease-in-out;
}
.container div {
cursor: move;
cursor: grab;
cursor: -moz-grab;
cursor: -webkit-grab;
}
.gu-mirror {
cursor: grabbing;
cursor: -moz-grabbing;
cursor: -webkit-grabbing;
}
现在你应该有一个有效的例子。

要解决"zone.js:1274 GET localhost:3000/ng2-dragula/ng2-dragula 404 (Not Found)"错误，请在systemjs.config.js
var map = {
...
'dragula': 'node_modules/dragula/dist/dragula.js',
'ng2-dragula': 'node_modules/ng2-dragula'
};
var packages = {
...
'dragula': { defaultExtension: 'js' },
'ng2-dragula': {defaultExtension: 'js' }
};
