npx react-native run-android：E/设备：同步期间出错：EOF

Question

我正在尝试在我真正的 Android 设备上运行 React Native 应用程序。我在跑步前检查了我的设备

adb devices

List of devices attached
3357425441473098        device

我开始于

npx react-native start

并在其他控制台中

npx react-native run-android

但出现错误..

就在那个错误之后。我失去了设备连接。

adb devices

什么也没显示..

在堆栈跟踪的底部我也看到了这个错误

我的设备是美国三星 Galaxy s9。当我使用Expo sdk时它可以工作。我的问题是什么？

反应本机：0.61.5

奇怪的是它在计算机启动后首先执行。然后我尝试重新连接手机，它再次弹出。

刚刚遇到了同样的问题。结果发现是我的 USB 数据线的问题。由于某种原因，安装过程因设备离线而被中断。我更换了电缆，一切又开始工作了。
