一、下载ngx-translate的依赖库

npm install @ngx-translate/core --save
npm install @ngx-translate/http-loader --save

二、创建国际化文件

三、在根模块(app.module.ts)中配置

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { GlobalManageComponent } from './global-manage/global-manage.component';
import { ForumtypeComponent } from './forumtype/forumtype.component';
// 国际化引入模块开始
import { TranslateModule, TranslateLoader } from '@ngx-translate/core';
import { TranslateHttpLoader } from '@ngx-translate/http-loader';
import {HttpClient, HttpClientModule} from '@angular/common/http';
export function createTranslateLoader(http: HttpClient) {return new TranslateHttpLoader(http, './assets/i18n/', '.json');  //国际化文件地址
}
//国际化引入模块结束@NgModule({declarations: [AppComponent,GlobalManageComponent,ForumtypeComponent,],imports: [BrowserModule,AppRoutingModule,HttpClientModule,  //国际化TranslateModule.forRoot({ //国际化loader: {provide: TranslateLoader,useFactory: createTranslateLoader,deps: [HttpClient]}})],providers: [],bootstrap: [AppComponent] //主视图
})
export class AppModule { }

四、在需要的模块使用
