错误消息：成员 'makes' 隐式具有 'any' 类型

Question

我收到一条错误消息：成员 'makes' 隐式具有 'any' 类型。

export class VehicleFormComponent implements OnInit {
makes;
constructor(private makeService:MakeService) { }
ngOnInit() {
this.makeService.getMakes().subscribe(makes=>{
  this.makes = makes
  console.log("MAKES",this.makes);
});

已编辑：

如果我添加 makes:any[]; 而不是 make:any，我会收到以下错误：

Property 'makes' has no initializer and is not definitely assigned in the constructor. at: '10,3' source: 'ts' code: '2564'

Answer 1

用特定类型声明你的变量 make 并初始化它

makes:any = [];

Answer 2

这就是您的代码应有的样子。

export class VehicleFormComponent implements OnInit {

makes: any;

constructor(private makeService:MakeService) { }

ngOnInit() {

this.makeService.getMakes().subscribe(makes=>{
  this.makes = makes
  console.log("MAKES",this.makes);

});
