运行我的应用程序后出现此错误:
错误:捆绑失败:错误:无法从
node_modules/react-navigation-stack/lib/module/vendor/views/Stack/StackView.js
解析模块react-native-safe-area-context
—:在项目中找不到 react-native-safe-area-context。
但是我为旧演示所做的相同。它工作得很好。
我不知道我在这里做错了什么。请检查我的代码:
对于安装:
- React Native 导航和手势处理程序:
npm install --save react-navigation
npm install --save react-native-gesture-handler
- 反应本机堆栈:
npm install --save react-navigation-stack
应用程序.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;
和 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 React-Native 的新手。我怎样才能解决这个问题?

我认为问题出在
SafeAreaView
,对于新的 react-native 版本,它已迁移到react-native-community/react-native-safe-area-view
。如果你想使用SafeAreaView
,你应该先安装它。新用途是这样的:
要安装它,您可以使用以下命令:
yarn add react-native-safe-area-view react-native-safe-area-context
。如果您不使用自动链接,则还必须链接它。有关它的详细信息,请参阅此 链接
