javascript - 关节.shapes.uml.js : Uncaught TypeError: Cannot read property 'Generic' of undefined

Question

我显示来自 JointJS 演示的 uml 图 https://github.com/clientIO/joint/tree/master/demo/umlcd在 Angular 8 中，我收到错误: joint.shapes.uml.js:13 Uncaught TypeError: Cannot read property 'Generic' of undefined

在 joint.shapes.uml.js:13
在 joint.shapes.uml.js:280

joint.shapes.uml.js:https://github.com/clientIO/joint/blob/master/dist/joint.shapes.uml.js

我做错了什么？

这是我的代码:

带有 jointJS 演示代码的 typescript 文件:

(我必须在演示代码中进行更改，例如:每个图实体必须具有属性和方法数组，并且属性 name 必须是 String [] 类型而不是 String。如果没有这些更改演示代码不起作用。)

在您的 angular.json 中，构建中包含的脚本顺序是错误的。

joint.shapes.uml.js 应在 joint.js 执行后执行。

正确顺序

 "scripts": [
              "./node_modules/jquery/dist/jquery.js",
              "./node_modules/lodash/lodash.js",
              "./node_modules/backbone/backbone.js",
              "./node_modules/jointjs/dist/joint.js"
              "./plugin/joint.shapes.uml.js",
            ]
