Question

我刚刚在Angular项目中安装了ng-bootstrap，然后添加了它的模块。但是我的CLI向我显示一个错误。

“警告在 ./node_modules/@ng-bootstrap/ng-bootstrap/fesm5/ng-bootstrap.js 9853：57-75在以下位置找不到“导出'ɵɵdefineInjectable” '@ angular / core'“

app.module

import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
import {NgbPaginationModule, NgbAlertModule} from '@ng-bootstrap/ng-bootstrap';

@NgModule({
  imports: [
    CommonModule,
    NgxPaginationModule,
    NgbModule,
    NgbPaginationModule,
    NgbAlertModule,
    RouterModule.forChild(routes)
  ],

如果您正在运行Angular 6应用程序，请确保已安装ng-bootstrap3.x.x。如果您确实需要使用特定版本的ng-bootstrap，请考虑升级Angular版本。有关兼容性的更多详细信息，请检查docs。
