angular - 错误 : Unexpected value 'undefined' exported by the module

Question

我正在使用 cli 构建一个 angular 4 应用程序。我创建了一个共享模块并将该模块导入到我的 appmodule 和 moviemodule 中。我收到编译时错误 Uncaught Error: Unexpected value 'undefined' exported by the module 'SharedModule'

谁能告诉我问题出在哪里我仔细检查了语法。我在这里遗漏了什么吗

错误信息

共享模块

import { NgModule }            from '@angular/core';
import { CommonModule }        from '@angular/common';
import { FormsModule }         from '@angular/forms';
import { GridModule } from '@progress/kendo-angular-grid';


@NgModule({
  imports:      [ CommonModule
                    , GridModule ],

  exports:      [ 
                    , CommonModule
                    , FormsModule 
                    , GridModule 
                    ]
})
export class SharedModule { }

移除 CommonModule 前面的逗号

exports: [ 
 remove this => , CommonModule 
                , FormsModule 
                , GridModule 
            ]
