Javascript 看起来u DEV_u_u的实现方式已经改变了。更新-[RCTBatchedBridge加载源：]

当我尝试准备我的react本机应用程序在设备上运行时，该应用程序会终止，并出现以下错误，我无法理解。我已经读到，节点需要是+4版本，但我正在运行4.1.2，所以我不认为这就是它。有什么想法吗

尝试将packager url更新为in-AppDelegate（iOS）。

按照升级指南，“手动更改”部分为我解决了此问题：

需要添加一个新的运行脚本阶段：

然后需要删除main.jsbundle文件：

main.jsbundle不再是必需的。选择您的设备作为XCode中的目标设备，然后点击运行按钮在设备上部署/运行。

这就是当前的URL。@SpencerPope为我的URL修复问题添加platform=ios&dev=true。如果您的url包含此选项，则不知道。您是否尝试过从预绑定的js代码运行？它对你有用吗？
