结合使用ng2-translate和jhipster，属性“ parser”在类型“ TranslateService”中是私有的，但在类型“ TranslateService”中不是私有的

Question

我正在使用angular-cli作为Jhipster的客户端，当我尝试构建我的项目时，我在Translate模块上遇到了问题，我试图升级到ngx-translate，但是我仍然遇到同样的问题。

这是我得到的错误：

“ TranslateService”不能分配给“ TranslateService”类型的参数。

shared-common.module.ts：

    import { NgModule, Sanitizer } from '@angular/core';
import { Title } from '@angular/platform-browser';
import { TranslateService } from 'ng2-translate';
import { AlertService } from 'ng-jhipster';
import {
    CarcheckappSharedLibsModule,
    JhiLanguageHelper,
    FindLanguageFromKeyPipe,
    JhiAlertComponent,
    JhiAlertErrorComponent
} from './';

export function alertServiceProvider(sanitizer: Sanitizer,
                                     translateService: TranslateService) {
    // set below to true to make alerts look like toast
    const isToast = false;
    return new AlertService(sanitizer, isToast, translateService);
}

@NgModule({
    imports: [
        CarcheckappSharedLibsModule
    ],
    declarations: [
        FindLanguageFromKeyPipe,
        JhiAlertComponent,
        JhiAlertErrorComponent
    ],
    providers: [
        JhiLanguageHelper,
        {
            provide: AlertService,
            useFactory: alertServiceProvider,
            deps: [Sanitizer, TranslateService]
        },
        Title
    ],
    exports: [
        CarcheckappSharedLibsModule,
        FindLanguageFromKeyPipe,
        JhiAlertComponent,
        JhiAlertErrorComponent
    ]
})
export class CarcheckappSharedCommonModule {}

您使用了错误的软件包。

import { TranslateService} from '@ngx-translate/core';

AlertService期望TranslateService中的@ngx-translate/core，您不能与另一个交换。    如果要使用ng2-translate，则必须创建自己的AlertService。
