react-native – React Native：borderBottomWidth无效

import React from 'react';
import { View,StyleSheet,Text } from 'react-native';
import Fonts from '../Fonts';
import Screen from '../Screen';

const styles = StyleSheet.create({
  container: {
    alignItems: "center",backgroundColor: "rgba(12,22,32,0.88)",flex: 1,justifyContent: "center",borderBottomWidth: 2,borderBottomColor: "#47315a",},content: {
    backgroundColor: "white",alignItems: "center",height: Screen.height() - 450.0,width: Screen.width() - 50.0,padding: 10,header: {
    alignItems: "center",paddingBottom: 10,color: "#0B1219",fontFamily: Fonts.Knockout31JuniorMiddleWeight,fontSize: 26.0,borderBottomWidth: 5,fontWeight: '300',});

const PlaceOrder = () => {
  return (
    <View style={[styles.container]}>
      <View style={[styles.content]}>
        <Text style={styles.header}>
          HEADER TEXT
        </Text>
        <Text>dzfaksjads fahksl</Text>
        <Text>
          We'll start preparing your blah when you blah blah
        </Text>
      </View>
    </View>
  );
};

export default PlaceOrder;

但是,bottomBorderWidth和bottomBorderColor不起作用.

当我更改它以使用borderWidth它工作,但我只希望底部有一个边框：

的package.json：
