Question

我正在使用“ ng serve”运行应用程序，但运行正常。但是，当我使用“ npm run build：ssr”构建应用程序后，该应用程序已成功构建。

构建并运行angular 7通用应用程序后，我在dist文件夹中收到这些错误。

/home/trd/TRD/dpm_home_page/dist/server.js:255862

proxyRequestMethods（索引，'_ index'，IDBIndex，[ ^ ReferenceError：未定义IDBIndex 在对象。（/home/trd/TRD/dpm_home_page/dist/server.js:255862:38)(/home/trd/TRD/dpm_home_page/dist/server.js:26:30）在Object.firebase（

Answer 1

我使用setwd("~/Desktop/test") a<-system('find . | grep -i ".gz$" |wc -l') while (a<5) { system('wget -nc -tries=1 -i list.txt') }而不是"@angular/fire": "^5.2.0-beta.3",我遇到了同样的问题，在实现“ AngularFirePerformanceModule”之后，我将其删除了； "angularfire2": "^5.1.0"，问题消失了。

如果您仍然想在app.module.ts中使用angulare / fire / performance模块，则可以这样做。

import { isPlatformBrowser } from '@angular/common';
import { AppComponent } from './app.component';

const importModuleArray: any[] = [ // your modules here ]

if (isPlatformBrowser) {
  require('@angular/fire/performance').then(module => {
    importModuleArray.push(module.AngularFirePerformanceModule);
  });}

@NgModule({
  **your declarated modules as AppComponent for example**
  ],
  imports: importModuleArray
  bootstrap: [AppComponent]
})

ReferenceError：在角度通用应用程序中未定义IDBIndex
