Question

我正在尝试在模拟器上运行React Native项目（奇怪的是，如果我在连接的（物理）设备上运行，它似乎运行正常。当我运行react-native run-ios时，出现以下错误：

events.js:167
      throw er; // Unhandled 'error' event
      ^

Error: listen EADDRINUSE :::8081
    at Server.setupListenHandle [as _listen2] (net.js:1286:14)
    at listenInCluster (net.js:1334:12)

Process terminated. Press <enter> to close the window

我尝试了所有可以找到的修复程序（例如“ killall”等），但都无济于事。感谢任何人都能提供的帮助。

干杯！

我尝试了各种KillAll建议，删除了npm文件夹，删除了ios build文件夹
