angular开发问题：Module not found: Error: Can't resolve '@angular/material/typings/esm5/dialog'

angular开发问题：Module not found: Error: Can’t resolve ‘@angular/material/typings/esm5/dialog’

Error回顾

在进行angular项目开发是使用material框架进行ui开发，其中某个功能使用到dialog组件。
在开发组件时候出现异常，报错如下:

Module not found: Error: Can’t resolve ‘@angular/material/typings/esm5/dialog’ in ‘E:\git\man\manpower-statistic\ManpowerFront\src\app\component\manpower\manpower-target-project\manpower-target-project-dialog’

该问题纠结了大半小时，没注意问题出在哪里。。。
后面重新备份文件，重新开发页面回顾问题重现过程。

Solution解决

发现问题出在imports上，material dialog应该导入@angular/material/dialog
实际导入了@angular/material/typings/esm5/dialog 。 汗！！！！，开发时候偶尔犯的错。

import {MAT_DIALOG_DATA, } from '@angular/material';
import {MatDialogRef} from '@angular/material/typings/esm5/dialog';

改为如下即可：

import {MAT_DIALOG_DATA, MatDialogRef} from '@angular/material'; 

Dialog部分功能代码如下

ts文件：

import {Component, Inject, OnInit} from '@angular/core';
import {FormBuilder, FormGroup} from '@angular/forms';
import {MAT_DIALOG_DATA, } from '@angular/material';
import {MatDialogRef} from '@angular/material/typings/esm5/dialog';

@Component({
  selector: 'app-manpower-relproject-dialog',
  templateUrl: './manpower-relproject-dialog.component.html',
  styleUrls: ['./manpower-relproject-dialog.component.css']
})
export class ManpowerRelprojectDialogComponent implements OnInit {

  dialogData: FormGroup;

  constructor(public dialogRef: MatDialogRef<ManpowerRelprojectDialogComponent>, @Inject(MAT_DIALOG_DATA) public data: any, private fb: FormBuilder) {}

  ngOnInit() {
    this.dialogData = this.fb.group({
      id: ['0'],
      name: [''],
      type: [''],
      display: [''],
      labPro: [''],
    });
    console.log('inject data: ' + this.data);
    this.dialogData.setValue(this.data);
  }

}

html文件：

<h2 class="dialog-title" mat-dialog-title>
  <span>用户信息span>
  <span style="float: right;margin-right: 20px;background-color: #ddd;border-radius: 3px;">
