我最近从React Native 0.53.3升级到了React Native 0.59.9，但我的应用程序在模拟器中不断崩溃。它会显示启动屏幕，然后崩溃，调试器UI中什么都没有，除了以下内容：
到“ws：//localhost：8081/调试器代理？角色=调试器&名称=Chrome”的WebSocket连接失败：建立连接时出错：网络：：错误连接被拒绝
我用react-native run-ios运行它，但是构建成功了，所以没有错误消息。当我试图在Xcode打开时打开应用程序时，它确实提到了无法找到.jsbundle文件的错误，在Xcode内部，我确实有一个红色的main.jsbundle，表明它丢失了。
所以找到这篇文章后：https://medium.com/the-react-native-log/first-time-deploying-with-react-native-f524eb3e705d#59ee
我尝试通过使用npm run build:ios脚本来执行它，该脚本引用了以下脚本：

"build:ios": "react-native bundle --entry-file='index.ios.js' --bundle-output='./ios/NFIBEngage/main.jsbundle' --dev=false --platform='ios' --assets-dest='./ios'"

但是当我运行它的时候，我得到了这个错误：

Loading dependency graph, done.

SO上与该错误相关的唯一帖子如下：

https://stackoverflow.com/questions/53326986/trace-the-node-type-spreadproperty-has-been-renamed-to-spreadelement-at-object

但这并不适用于我的情况。
问题似乎与node_modules内的@babel库有关，我曾尝试执行rm -rf node_modules，但没有解决它。
此项目的当前版本是否不再支持这些开发依赖项之一？

"devDependencies": {
    "async": "2.6.0",
    "babel-cli": "6.24.1",
    "babel-eslint": "8.0.2",
    "babel-jest": "23.0.0",
    "babel-plugin-module-resolver": "3.0.0",
    "babel-preset-env": "1.4.0",
    "babel-preset-flow": "6.23.0",
    "babel-preset-react-native": "4.0.0",
    "babel-preset-stage-2": "6.24.1",
    "babel-watch": "2.0.6",

如何解决此问题（升级到React Native 0.59.9）？
我已经了解到，在RN 0.49之后，我们使用index.js而不是index.ios.js，当我创建一个模拟版本以尝试获得一个基线应用程序来尝试弄清楚发生了什么时，我验证了这一点。
我执行了以下操作：

✗ mv index.ios.js index.js
➜  engage-application.mobile git:(feature/3.6.2_upgrade) ✗ rm index.android.js
➜  engage-application.mobile git:(feature/3.6.2_upgrade) ✗ react-native bundle --entry-file ./index.js --platform ios --bundle-output ios/main.jsbundle --verbose

但无论如何我还是会得到同样的错误。
