React Native:未捕获(承诺)错误:DeltaPatcher 在初始化时应该收到一个基本bundle

Question

我最近在 http://localhost:8081/debugger-ui/中遇到了这条错误消息，上面写着：

Uncaught (in promise) Error: DeltaPatcher should receive a base Bundle when being initialized
at DeltaPatcher.applyDelta 
at deltaUrlToBlobUrl
at async getBlobUrl 
at async WebSocket.ws.onmessage 
applyDelta  
deltaUrlToBlobUrl       
async function (async)      
ws.onmessage

当我尝试从模拟器打开我的 React Native 应用程序时，会发生此错误，尽管index.ios.js文件成功构建，但应用程序仍卡在启动屏幕上并出现上述错误。

我不知道它指的是什么，也不知道从哪里开始调试这个，或者这个DeltaPatcher来自哪个包。

就我在收到此错误之前所做的事情而言，这就是我正在做的事情：

• 反应本机选项卡视图的包修复

• 必须删除 npm-shrinkwrap.json 才能运行 npm 安装

• 必须卸载并重新安装反应本机启动画面才能通过 使用 Xcode 构建失败

• 必须在具有项目：写入权限的哨兵中创建新的auth.token。 通过 403 错误

• 手动从项目中完全删除Instabug

• 修复了旋转套件和alerts.filter错误

  在此之后，应用程序可以正常工作，但是后来我不得不 解决 Xcode 中的以下错误。

• 删除了与
  错误相关的8CBD27422B744FC9C0407AA3PhaseScriptExecution

  引用

• 将配置重构为以前的版本以消除
  AppReactNative崩溃的错误

• 修改了容器文件配置以反映应用中心升级

• 删除 instabug 引用和 spinkit 引用

然后我回忆起我安装了 Metro 版本 29 以试图解决另一个问题。所以我完全删除了 Metro 作为一个包，但这还没有解决它。

我正在运行的脚本是react-native run-ios，这是我package.json文件：

Answer 1

好的，在我删除 Metro 版本 29 之后，我只是继续重复运行这些命令：

rm -rf node_modules && npm install && npm run setup && react-native run-ios

现在，它启动经过启动画面，并显示另一个但更熟悉的错误。
