Angular 7 CI rxjs / Operators找不到模块

Question

我尝试使用Circle CI按照以下配置为我的角度项目设置CI：https://angular.io/guide/testing#configure-project-for-circle-ci

但是，当ng test运行时，我收到以下错误：

ERROR in src/app/account/login-form/login-form.component.ts(4,26): error TS2307: Cannot find module 'rxjs/Operators'.

在本地，如果我删除node_modules/并运行npm install后跟npm test我对rxjs没有任何问题。

我的package.json：

"dependencies": {
  "@angular/animations": "7.2.4",
  "@angular/common": "7.2.4",
  "@angular/compiler": "7.2.4",
  "@angular/core": "7.2.4",

  "node-sass": "4.11.0",
  "protractor": "~5.4.0",

  "tslint": "~5.9.1"
}

login-form.component.ts中的违规行：

import { Subscription } from 'rxjs';
import { finalize } from 'rxjs/Operators';

我可以提供有用的任何来源，但我不知道什么是相关的。

Answer 1

那是因为你应该从rxjs/operators导入，而不是rxjs/Operators。
