软件包更新后，React Native应用卡在初始屏幕上

问题描述

我的应用程序以前运行正常，没有构建或运行时错误。然后，我将react-native-agora从^ 2.9.1更新为^ 3.0.1-rc.4。 发生了崩溃问题，该问题已由

解决

• pod install
• react-native start --reset-cache

我现在的问题是，应用程序停留在初始屏幕上，并在iOS RN v0.61.5上出现此错误：

Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication)

到目前为止，我已经尝试过：

• 添加index.ios.js文件并添加入口点代码
• 删除并重新安装node_modules
• npm cache clean
• 使用Xcode清理和重建项目
• 重新启动计算机
• killall -9 node
• react-native start --reset-cache
• 在模拟器中删除应用并重新构建/运行
• 已删除的pod文件夹和pod install
• 注释掉所有react-native-agora代码

我没有 ：

• 在此agora程序包上运行任何形式的react-native link。我正在使用v0.61.5

也：

• 因为react-navigation在.61.5中是自动链接的，所以我相信Xcode中应该有某种开发容器。我没看它什么时候工作，所以没有什么可比的。但我在开发人员窗格中看不到react-navigation，但我看到了其对等依赖项

我的package.json：

"dependencies": {
        "@react-native-community/cli": "^4.3.0","@react-native-community/clipboard": "^1.2.2","axios": "^0.19.2","moment": "^2.24.0","moment-timezone": "^0.5.27","prop-types": "^15.7.2","react": "16.9.0","react-native": "^0.61.5","react-native-agora": "^3.0.1-rc.4","react-native-algolia-dropdown": "^1.6.0","react-native-calendars": "^1.220.0","react-native-chart-kit": "^4.3.0","react-native-code-push": "^6.0.0","react-native-extended-stylesheet": "^0.12.0","react-native-firebase": "^5.6.0","react-native-gesture-handler": "^1.5.2","react-native-image-crop-picker": "^0.26.1","react-native-material-dropdown": "^0.11.1","react-native-reanimated": "^1.4.0","react-native-responsive-screen": "^1.4.1","react-native-safe-area-context": "^0.6.2","react-native-screens": "^1.0.0-alpha.23","react-native-snap-carousel": "^3.8.4","react-native-splash-screen": "^3.2.0","react-native-svg": "^9.13.6","react-native-view-shot": "^3.1.2","react-native-webview": "^9.4.0","react-navigation": "^4.0.10","react-navigation-drawer": "^2.3.3","react-navigation-stack": "^1.10.3","react-redux": "^7.1.3","redux": "^4.0.4","redux-persist": "^6.0.0","redux-thunk": "^2.3.0","rn-fetch-blob": "^0.11.2"
    },

index.js和index.android.js相同：

import { AppRegistry } from 'react-native';
import App from './App';
import 'react-native-gesture-handler';
import { name as Project } from './app.json';

AppRegistry.registerComponent(Project,() => App);

编辑（调试器输出）：

• 很多Require cycles are allowed,but can result in uninitialized values. Consider refactoring to remove the need for a cycle.都是从各种来源输出的，从我的组件到Firebase，再到其他npm软件包
• 关于仍然尝试使用react-native-agora软件包的很多抱怨

如何解决此问题？

解决方法

React Native Agora v3.x与v2.x不向后兼容。请考虑阅读API参考，示例应用程序，然后迁移到新的API。

v3准系统快速入门（自述文件尚未更新）：https://github.com/technophilic/Agora-RN-Quickstart/tree/sdk-v3

API参考：https://agoraio-community.github.io/react-native-agora/globals.html

,

在这种情况下，在最初尝试出于调试目的删除所有存在的软件包之后，仍然存在一些新近更新的软件包。通过从react-native-agora完全删除所有代码，Ive现在可以正常运行该应用程序。他们的所有文档和示例项目都没有针对新版本进行更新的问题。
