ng-bootstrap不显示工具提示 [英] ng-bootstrap not displaying tooltip

问题描述

我想显示一个工具提示.我去了ng-bootstrap并集成了该代码.正在获取控制台错误.

I want to display a tooltip. I went to ng-bootstrap and integrated that code. Getting console error.

core.es5.js:1020 ERROR Error: Uncaught (in promise): Error: No provider for 
NgbTooltipConfig!
Error: No provider for NgbTooltipConfig!
at injectionError (core.es5.js:1169)

at createClass (core.es5.js:10920)

在app.module.ts中添加了这些行

Added these lines in app.module.ts

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

@NgModule({
  imports: [    
    NgbModule
  ]
})

使用命令安装了ng-bootstrap

Installed ng-bootstrap using command

npm install --save @ng-bootstrap/ng-bootstrap

推荐答案

您应该导入NgbModule.forRoot()而不是NgbModule.

确切的方法对于根(顶层)而言会略有不同 模块，其最终应类似于(注意 NgbModule.forRoot()):

The exact method will be slightly different for the root (top-level) module for which you should end up with the code similar to (notice NgbModule.forRoot()):

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

@NgModule({
  declarations: [AppComponent, ...],
  imports: [NgbModule.forRoot(), ...],
  bootstrap: [AppComponent]
})
export class AppModule {
}

应用程序中的其他模块可以简单地导入NgbModule:

Other modules in your application can simply import NgbModule:

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

@NgModule({
  declarations: [OtherComponent, ...],
  imports: [NgbModule, ...]
})
export class OtherModule {
}
