将@ angular / pwa添加到我的应用后
ng add @angular/pwa --project appName
我得到错误
core.js：34469未捕获的TypeError：无法读取registerNgModuleType上未定义的属性“ id”
如果我appName.module.ts从进口中删除
ServiceWorkerModule.register("ngsw-worker.js", {
enabled: environment.production
})
应用再次正常工作。
添加了Angular.json
"serviceWorker": true,
"ngswConfigPath": "projects/tol5-admin-app/ngsw-config.json"
这是我的package.json

这种情况经常发生，当你混淆imports和declarations相关模块（或其它某种这样的混淆）。例如，您可能已经在数组中放置了一个组件，在该imports数组中仅应“声明”模块。该组件应该在declarations数组中。
