【问题描述】：
我关注How can I use JointJS with an application built with Angular CLI? 在 Angular 上安装 JointJS。无论如何，我在启动项目时遇到了这个问题：
Module not found: Error: Can't resolve './node_modules/jointjs/dist/joint.js'
我试图改变这个导入
const joint = require('./node_modules/jointjs/dist/joint.js');
用这个：import * as joint from 'jointjs/dist/joint';
这样我在启动项目时没有问题但是我不能使用这种方法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。我认为这是一个进口问题。
这是我的 angular-cli.json：

你有什么想法吗？
【问题讨论】：
-
你安装了联合js分型吗？
-
是的，我部分解决了这个问题，我安装了jointjs，将其写入package.json的依赖项中，然后执行npm install（不直接使用npm install jointjs）...现在我看到了图表但我有这个错误：
TypeError: Backbone is undefined <anonymous> <anonymous> __webpack_require__ __webpack_require__ webpackJsonpCallback <anonymous> -
看起来你需要输入所有其余依赖项的类型
-
我安装了关节、jointjs 类型、lodash 和骨干......我看到了我写的例子，但是有这个错误。可能是导入问题？
-
我添加了关于我的 package.json 和 angular-cli.json 的新信息，我不知道它们是否有用
