React Native不使用Android设备的“入门”指南

Question

我一直试图在我的Windows PC上启动并运行基本的React原生程序，但无法将其加载到通过USB连接的Pixel 3上。我已经将Node.js重新安装到12.13.1。以下是当我执行npx react-native run-android时得到的结果

我只能让它这么做。我的手机说它无法加载脚本，并确保metro服务器正在运行或index.android.bundle已经正确打包。有什么建议吗？

Answer 1

我发现问题源于metro的一些代码与最新节点版本处理正则表达式的方式不太好。在这里可以找到一个临时的解决办法。一旦解决了这个问题，我就可以运行这里提供的代码来构建缺少的index.android.bundle了。
