在为 Android 模拟器启动 React Native 应用程序时出现此问题。不过它在 iOS 上运行良好。

Answer 1

将它添加到你的 android/buld.gradle 文件的 allprojects 区域

    def REACT_NATIVE_VERSION = new File(['node', '--print',"JSON.parse(require('fs').readFileSync(require.resolve('react-native/package.json'), 'utf-8')).version"].execute(null, rootDir).text.trim()) allprojects {
    configurations.all {
        resolutionStrategy {
            // Remove this override in 0.65+, as a proper fix is included in react-native itself.
            force "com.facebook.react:react-native:" + REACT_NATIVE_VERSION
        }
    }
}
