最佳答案
获取此错误: Error: bundle 未能成功: Error: 无法解析模块“ response-national-safe-area-context”
在运行我的应用程序后，我得到了这个错误:
错误: 无法解析来自
node_modules/react-navigation-stack/lib/module/vendor/views/Stack/StackView.js的模块react-native-safe-area-context: 无法在项目中找到反应-本机-安全-区域-上下文。
但是和我以前的样带一样，效果非常好。
我不知道我在这里做错了什么。请检查我的代码:
安装:
- 返回本地导航和手势处理程序:
npm install --save react-navigation
npm install --save react-native-gesture-handler
- 反应堆原生堆栈:
npm install --save react-navigation-stack
App.js
import { createAppContainer } from "react-navigation";
import { createStackNavigator } from "react-navigation-stack";
import FirstOptionsPage from "./FirstOptionsPage";
const MainNavigator = createStackNavigator(
{
FirstOptions: FirstOptionsPage
},
{
defaultNavigationOptions: {
headerStyle: {
// backgroundColor: '#28F1A6',
elevation: 0,
shadowOpacity: 0
},
headerTintColor: "#ca375e",
headerTitleStyle: {
fontWeight: "bold",
color: "#161616"
}
}
}
);
const App = createAppContainer(MainNavigator); // For setting Navigation Stack
export default App;
还有 FirstOptionsPage.js:
import React from "react";
import {
SafeAreaView,
StyleSheet,
View,
Text,
ScrollView,
Switch
} from "react-native";
export default class FirstOptionsPage extends React.Component {
static navigationOptions = {
title: "Preferences"
};
constructor(props) {
super(props);
this.state = {
switch1Value: false
};
}
toggleSwitch1 = value => {
this.setState({ switch1Value: value });
console.log("Switch 1 is: " + value);
};
render() {
const { navigate } = this.props.navigation;
return (
<SafeAreaView style={styles.mainContainerStyle}>
<View style={styles.subContainerStyle}>
<Text style={styles.subtitleTextStyle}>Someone likes my post</Text>
<View style={styles.switchStyle}>
<Switch
onValueChange={this.toggleSwitch1}
value={this.state.switch1Value}
thumbColor={MAGENTA_COLOR_CODE}
trackColor={{
false: GREY_COLOR_CODE,
true: DARK_GREY_COLOR_CODE
}}
/>
</View>
</View>
</SafeAreaView>
);
}
}
我是反应原住民的新手，我该怎么补救？
