错误:模块导出的意外值'undefined'

Question

我正在使用cli构建一个角度4应用程序.我创建了一个共享模块,并在我的appmodule和moviemodule中导入了该模块.我收到编译时错误未捕获错误:模块'SharedModule'导出的意外值'undefined'

有人能告诉我问题是什么我仔细检查了语法.我在这里错过了一些东西

                    , GridModule ],

  exports:      [

删除前面的逗号 CommonModule

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