带有SystemJS和TypeScript的D3 v4

我正在尝试使用SystemJS和TypeScript设置最新版本的d3，但似乎有些谜题在我身边并不合适 .

Summary

基本上，在我将所有依赖项和@types安装到node_modules之后，我配置了SystemJS来加载这些依赖项 .

现在这种行为很奇怪，比如：

• 使用 import * as d3 from 'd3'; 我收到 ModuleNamespace

• 通过使用 import d3 from 'd3'; 我收到了正确的d3对象，但TS抱怨：

• Module '"ABSOLUTE_PATH/node_modules/@types/d3/index"' has no default export.' at: '2,8' source: 'ts'

Code

systemjs.config.js

(function () {
  SystemJS.config({

      'npm:': 'node_modules/'
