我是React Native的新手。我在世博会XDE中创建了一个新的空白项目，当我尝试在我的Android设备上运行它时，每次它在启动画面后崩溃时。这只是一个简单的空白应用程序。
没有日志或错误。世博会应用程序只需返回第一页。
设备： 安卓 7
XDE：世博版本 2.21.00
应用.js
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
export default class App extends React.Component {
render() {
return (
<View style={styles.container}>
<Text>Open up App.js to start working on your app!</Text>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',
},
});

哪个操作系统？Mac、Win还是Linux？如果您使用的是 Linux，您是否使用此命令打开了 XDE 客户端？
On Linux, open with chmod a+x xde*.AppImage and ./xde*.AppImage
无论您的操作系统如何，您确定您有...
- 安装了最新版本的节点？
- 安装了最新版本的守望者？
黑暗中的镜头，但是一旦您更新了上述内容，我会开始一个新项目并重试。
更新：更仔细地查看您的日志，我可以看到您在 Windows 上，因为路径是"C：\..."，因此请忽略上面的 linux 注释。我仍然认为您的环境设置不正确。重新安装节点和/或守望者可能会有所帮助（很可能是节点）。您也可以尝试安装纱线，看看这是否有所作为。有时它对我有用。
