我正在处理角度应用程序，当我打开我的项目时，它给了我如下错误

ERROR NullInjectorError: R3InjectorError(IndexModule)[InjectionToken NGX_ECHARTS_CONFIG -> InjectionToken NGX_ECHARTS_CONFIG -> InjectionToken NGX_ECHARTS_CONFIG -> InjectionToken NGX_ECHARTS_CONFIG]:

尝试安装ngx-echarts

npm install echarts -S
npm install ngx-echarts -S

仍然得到同样的上述错误

我已经签出 angular 项目并尝试ng serve使用此命令运行我收到以下错误。

我已经有一个正在运行的 Angular 应用程序，因为有扩展的功能，我必须为应用程序实现路由和登录页面。以前没有路由，作为路由的一部分，我添加了以下代码。

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common'
import { HttpClientModule } from '@angular/common/http';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { RouterModule } from '@angular/router';
import { AppComponent } from './app.component';
import { EditorModule } from '@tinymce/tinymce-angular';
import { AngularEditorModule } from '@kolkov/angular-editor';
import { NgxUiLoaderModule } from 'ngx-ui-loader';
import { AppRoutingModule } from './app-routing.module';

@NgModule({
    declarations: [
        AppComponent
    ],
    imports: [
        BrowserModule,
        FormsModule, …
