android - 无法在 react-native run-android 上的设备上安装应用程序

Question

我无法运行任何 react-native 项目。 它说已经有一个进程在运行。端口 8081 被在我的 MAC 上运行的迈克菲防病毒软件占用。而且我无论如何也杀不死它(虽然我不应该杀它，但我试过了，看起来它永远不会死!毕竟 SUDO 没有力量!)

引用#7308 #9145和 stackoverflow ，我尝试在端口 8082 上运行。服务器启动，但是，run-android 仍然失败，提示未找到设备。 我同时打开了我的设备(打开 Debug模式的 Galaxy S7 Edge)和 Genymotion。

React Native 版本详情 -

SATJAGAN-M-T0HZ:react-native-card-modal satjagan$ react-native -v
react-native-cli: 1.0.0
react-native: 0.37.0

Genymotion 活跃且可用 -

运行应用程序的终端日志- (有趣的是它说JS Server not recognized，那里有什么问题吗)？

不幸的是，卸载 McAfee 不是一个选项 :( 如果我有自由，我会先做。

React-Native 仍在尝试连接到 8081. 上的打包器通常你打开开发菜单并指定一个不同的端口，但在你的情况下你甚至无法开始。

您似乎无法以其他方式指定端口。我认为您可能有两种选择:

1. 通过开发菜单临时终止 McAfee、安装和更改端口，如下所述:https://facebook.github.io/react-native/docs/troubleshooting.html#terminating-a-process-on-port-8081

2. 更改此文件:https://github.com/facebook/react-native/blob/292cc82d0ebc437a6f1cdd2e972b3917b7ee05a4/Libraries/Core/Devtools/getDevServer.js
