**这是我收到的错误代码，下面是我的完整代码。我用 yarn 安装了 react-native-video，然后将其链接到 ios 和 android ** 我在从“react-native-video”中包含 {Video} 后收到此错误。否则我的代码运行正常。我想在我的应用中有一个背景视频，但它不起作用。

import React, {Component,Fragment} from 'react';
import { StyleSheet, Text, View, ImageBackground,Image,TouchableOpacity,Dimensions} from 'react-native';
import Video from 'react-native-video';



import Img from './Src/Assets/Images/3.jpg';
import arrow from './Src/Assets/Icons/arrow_right.png';
import videomp4 from './Src/Assets/video.mp4';

const { height } = Dimensions.get("window");


export default class getStarted extends Component {






    render() {


      return (
        <View style={styles.container}  >
