角材料生产的构建问题

Question

在Angular 7项目中，我尝试使用命令ng serve --prod在生产模式下为Angular项目提供服务。但是我遇到了有关angular的材质库的错误，例如：

ERROR in : There is no directive with "exportAs" set to "ngForm" (" *ngIf="cardList?.length > 0">
                                <form name="form" autocomplete="off" [ERROR ->]#form ="ngForm">
                                    <div class=" form-group amount">
               ")
: There is no directive with "exportAs" set to "ngModel" (" type="number" appNumbersdirective placeholder="Enter Amount"  min="1" name="CheckAmount" required  [ERROR ->]#CheckAmount="ngModel" [(ngModel)]="bankInfo.CheckAmount">
                                          ")
: Can't bind to 'ngModel' since it isn't a known property of 'input'. ("rsdirective placeholder="Enter Amount"  min="1" name="CheckAmount"required  #CheckAmount="ngModel" [ERROR ->][(ngModel)]="bankInfo.CheckAmount">
                                            <mat-error *ngIf="Che")
: 'mat-error' is not a known element:
1. If 'mat-error' is an Angular component, then verify that it is part of this module.
2. If 'mat-error' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("eckAmount="ngModel" [(ngModel)]="bankInfo.CheckAmount">
                                            [ERROR ->]<mat-error *ngIf="CheckAmount.errors?.required">
                                                Amou")

我已经在MatFormFieldModule导入部分中加入了app.module.ts，但是仍然无法解决问题。

此外，这是我的一个文件的摘要，该文件引起错误：

    [RouterModule.forChild(routes)]
  ]
})
export class TransferMoneyModule { }

      <mat-tab-group>

        <mat-tab label="Transfer to Bank">
            <!-- <mat-icon class="example-tab-icon">thumb_up</mat-icon> -->
            <div>

                                          <mat-error *ngIf="CheckAmount.errors?.required">
                                              Amount is required.  
                                          </mat-error>
                                          <mat-error *ngIf="bankInfo.CheckAmount >= 0 ">
                                              Amount cannot be zero
                                          </mat-error>
                                        </mat-form-field>
                                      </div>
                                  </div> .......

一切在开发模式下都可以正常工作，但是在生产模式下检查时会产生错误。我对Angular完全陌生。
