javascript - typescript 错误 TS1128 : Declaration or statement expected

Question

遇到 typescript 错误，我花了几个小时试图修复。它指向我的 game-details.component.ts(26,54)，对我来说它看起来完全没问题。

另外，当我在我的 game-detail.component webpack 中 CTR + S 时，编译成功并且我的程序运行良好。任何人都可以向我解释为什么它会这样工作吗？

代码如下:

import { Component, OnInit, Input } from '@angular/core';
import { ActivatedRoute, Params } from '@angular/router';
import { Location } from '@angular/common';

import { GameService } from '../../game.service';
import { UserComment } from '../../comment.model';

@Component({
  selector: 'app-game-detail',
  templateUrl: './game-detail.component.html',
  styleUrls: ['./game-detail.component.css'],
  providers: [GameService]
})
export class GameDetailComponent implements OnInit {

  gameKey: string;
  gameDetail;

  constructor(private route: ActivatedRoute, private location: Location, private gameService: GameService) { }

  ngOnInit() {
    this.route.params.forEach((urlParameters)=> {
      this.gameKey = urlParameters['id'];
    });
    this.gameService.getGameByKey(this.gameKey).subscribe(dataLastEmittedFromObserver => {
       this.gameDetail = dataLastEmittedFromObserver;);
      }

      addComment(com: string) {
      const newComment: UserComment = new UserComment(com);
      this.gameDetail.comments.push(newComment);
      this.gameService.updateComments(this.gameDetail);
      // this.toggleDisplay();
    }
}

如果您查看您的代码，它在 ngOnInit() 中存在问题，您几乎没有错放括号，请将其更改为

ngOnInit() {
  this.route.params.forEach((urlParameters) => {
            this.gameKey = urlParameters['id'];
        });      
  this.gameService.getGameByKey(this.gameKey)
  .subscribe(dataLastEmittedFromObserver => {
            this.gameDetail = dataLastEmittedFromObserver;
        });
}
