无法解析BsModalService的所有参数 [英] Can't resolve all parameters for BsModalService

问题描述

我正在向我的spfx angular 2应用程序添加一个模态.我试图通过 http://valor-software.com/ngx跟踪ngx-bootstrap-modal -bootstrap/#/modals .但我收到此错误:

I'm adding a modal to my spfx angular 2 application. I was trying to follow ngx-bootstrap-modal through http://valor-software.com/ngx-bootstrap/#/modals. but I am getting this error:

Unhandled Promise rejection: Can't resolve all parameters for AppComponent: (?). ; Zone: <root> ; Task: 

这是我的代码的样子:

package.json

  }
}

我的html调用该函数:

my html that calls the function:

 <button (click)="addApp();" class="ms-Button ms-Button--primary">
            <span class="ms-Button-label">Add Application</span>
        </button>

我的app.component.js的片段

snippet of my app.component.js

import { Component, OnInit,ViewEncapsulation, ViewContainerRef } from '@angular/core';
import { AppSettings } from './shared/app.settings';
import { IApplicationEntity } from './shared/app.entities';
import { BsModalService } from 'ngx-bootstrap/modal';
import { BsModalRef } from 'ngx-bootstrap/modal/modal-options.class';

export class AppComponent implements OnInit {
    bsModalRef: BsModalRef;

    constructor(private modalService: BsModalService) {}

    public addApp() {
        console.log("open the modal");
        let list = ['Open a modal with component', 'Pass your data', 'Do something else', '...'];
        this.bsModalRef = this.modalService.show(ModalContentComponent);
        this.bsModalRef.content.title = 'Modal with component';
        this.bsModalRef.content.list = list;
    }
}

这是我的app.module.ts

and this is my app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ModalModule } from 'angular2-modal';
import { BootstrapModalModule } from 'angular2-modal/plugins/bootstrap';
import { AppComponent } from './app.component';
import { AppSettings } from './shared/app.settings';
import { AppLoadingComponent } from './shared/loading/app.loading';
import { AppNotifyComponent } from './shared/notify/app.notify';
import { BsModalService } from 'ngx-bootstrap/modal';


@NgModule({
    imports: [BrowserModule 
    ],
    declarations: [
        AppComponent, 
        AppLoadingComponent,
        AppNotifyComponent],
    bootstrap: [AppComponent],
})

export class AppModule {}

推荐答案

在您的app.module.ts中，您没有将ModalModule添加到imports array，解决方案应从ngx-bootstrap导入ModalModule并添加它到您的导入数组.

From your app.module.ts, you didn't add ModalModule to imports array, the solution should be import ModalModule from ngx-bootstrap and add it to your imports array.

import { ModalModule } from 'ngx-bootstrap';
// or
import { ModalModule } from 'ngx-bootstrap/modal';

imports: [BrowserModule, ModalModule.forRoot()],
                         ^^^^^^^^^^^^^^^^^^^^^   mention here
