Unhandled Promise rejection: Template parse errors:
‘row’ is not a known element:
1. If ‘row’ is an Angular component,then verify that it is part of this module.
2. If ‘row’ is a Web Component then add “CUSTOM_ELEMENTS_SCHEMA” to the ‘@NgModule.schemas’ of this component to suppress this message. (“[ERROR ->]

AppModule-

import { BrowserModule } from '@angular/platform-browser';
import { NgModule,CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import { AppComponent } from './app.component';

这真的很简单.到底他妈发生了什么？
