未捕获（承诺）：错误：StaticInjectorError(AppModule)[选项]

2024-04-13

我有一个奇怪的错误。通常（我用谷歌搜索过），在这种错误情况下，Angular 在方括号中指定到底是哪个模块/服务/提供者/等导致了问题。然而这里只说options.

我尝试添加HttpClientModule, HttpModule, Options供应商/进口商 - 没有成功。

尝试遵循此调试指南在缩小的 Angular javascript 中调试未知提供者 https://stackoverflow.com/questions/23480591/debugging-unknown-provider-in-minified-angular-javascript但它也让我一无所获（不invoke在调用堆栈上，仅调用与Zone)

my app.components.ts看起来像这样：

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  template: `<router-outlet></router-outlet>`,
})
export class AppComponent {
  constructor() {}
}

defaultErrorLogger @ core.js:1448

当我进入调试模式时，调用错误的最后一个函数是：

function defaultErrorLogger(console) {
    var values = [];
    for (var _i = 1; _i < arguments.length; _i++) {
        values[_i - 1] = arguments[_i];
    }
    console.error.apply(console, values);
}

这是对我有用的（Angular 7）：

首次导入HttpClient模块在你的应用程序模块.ts如果你没有：

import { HttpClientModule } from '@angular/common/http';
...
imports: [
        HttpClientModule
    ],

然后更改您的服务

@Injectable()
export class FooService {

to

@Injectable({
    providedIn: 'root'
})
export class FooService {

希望能帮助到你。

通过以下任一方式确定哪些注射器将提供注射剂 将其与 @NgModule 或其他 InjectorType 关联，或者通过 指定该注射剂应在其中之一中提供 以下喷油器：

'root' ：大多数应用程序中的应用程序级注入器。

'platform' ：一个特殊的单例平台注入器，由平台上的所有应用程序共享 页。

'any' ：在每个模块中提供唯一的实例（包括 惰性模块）注入令牌。
