javascript - 错误 TS1005: ',' 预期，编译 Angular 6 项目失败

Question

每当我编译时，我都会收到此错误消息

ERROR in src/app/form/form.component.ts(22,39): error TS1005: ',' expected.

这是错误指向的完整代码：

import { Component, OnInit } from '@angular/core';
import { CommService } from '../services/comm.service';

@Component({
  selector: 'app-form',
  templateUrl: './form.component.html',
  styleUrls: ['./form.component.css']
})
export class FormComponent implements OnInit {


  user = {
    Doctor: '',
    Patient: '',
    Type: '',
    Diagnosis: ''
  };

  constructor(private CommService: CommService) { }

  ngOnInit() {
    this.CommService.setData(this.user);

  }

}

上面的代码是一个简单的形式，它接受输入（user={}）并将其传递给服务（CommService.setData）

这是 CommService 代码：

import { Injectable } from '@angular/core';
import { Observable, of, Subject } from 'rxjs';
import { FormComponent } from '../form/form.component';

@Injectable()
export class CommService {

  getData$: Observable<any>;
  private getDataSubject = new Subject<string>();


  users = {
    Doctor: '',
    Patient: '',
    Type: '',
    Diagnosis: ''
  };

  constructor() { }

  setData (data: any[]) {
    this.users = data;
  }

  getData() {
    return this.users;
  }
}

我是一个初学者，所以我敢打赌我的错误很简单，如果你能帮助我，我将不胜感激

更新：几个聪明的家伙建议我检查“package.json”中的 typscript 版本，这是我发现的：`“typescript”：“~2.7.2”，所以我更新到 2.9，但不知何故我仍然有相同的错误！

另外，这是整个 package.json 文件

检查您是否使用最新版本的打字稿，如果没有，请尝试https://stackoverflow.com/a/46399668/1817690。

此外，of在旧版本rxjs中将无法使用，因此请在您的服务文件中进行更改

import { Observable, Subject } from 'rxjs';

并使用

import "rxjs/add/observable/of";

或者

import { of as observableOf } from 'rxjs/observable/of';

阅读typescript 中为 Observable 的 import .of()给出的答案
