我已将我的Angular 4应用程序更新为Angular 8。应用程序在开发构建中运行良好，但在生产构建中中断。加载应用程序时出现以下错误。

未捕获的类型错误：无法读取 d3.js:8 at Object../node_modules/d3/d3.js (d3.js:9554) at webpack_require (bootstrap:78) at Module../src/ 处未定义的属性“文档” app/pages/home/dashboard/map/map.component.ts (main-es2015.js:9841) at webpack_require (bootstrap:78) at Module../src/app/pages/home/home.routes.ts ( home.routes.ts:2) at webpack_require (bootstrap:78) at Module../src/app/pages/home/home.module.ts (home.event.bus.ts:5) at webpack_require (bootstrap:78) )

我的tsconfig.json文件看起来像这样。
