集成JointJS

Question

我跟随How can I use JointJS with an application built with Angular CLI?在Angular上安装了JointJS。无论如何，当我开始这个项目时，我遇到了这个问题：

Module not found: Error: Can't resolve './node_modules/jointjs/dist/joint.js'

我尝试更改此导入

const joint = require('./node_modules/jointjs/dist/joint.js'); 

有了这个：import * as joint from 'jointjs/dist/joint';

通过这种方式，当我开始项目时，我没有问题，但是我不能使用这种类型的方法let m1 = new joint.shapes.devs.Model，因为我有这个错误：

TS2339:Property 'devs' does not exist on type 'typeof shapes'

使用像这样的方法：let rect2 = new joint.shapes.basic.Rect或这个let link = new joint.dia.Link，我没有问题。我认为这是一个重要的问题。

这是我的angular-cli.json：

      "config": "./karma.conf.js"
    }
  },
  "defaults": {

你有什么想法吗？

Answer 1

我认为你需要按照joint.js的要求在你的"dependencies"中安装backbone和lodash。

它们不仅仅是开发("dev-dependencies")所需要的。这就是它崩溃的原因
