【问题描述】：

React Native 应用在 Debug 配置中运行良好，但在我为 Release 构建时崩溃，Xcode 提供：

Unhandled JS Exception: Error: Requiring unknown module "undefined"., stack:

这是我的依赖项：

"dependencies": 
    "@react-native-async-storage/async-storage": "^1.15.5",
    "@react-native-clipboard/clipboard": "^1.8.1",
    "@react-native-community/slider": "^3.0.3",

    "react-native-svg-charts": "^5.4.0",
    "react-native-svg-transformer": "^0.14.3",
    "react-native-vector-icons": "^8.1.0",
    "react-navigation": "^4.4.4",
    "react-navigation-stack": "^2.10.4",
    "rn-circular-slider": "^1.1.0"
  

我怀疑是 jsdom-jscore-rn 导致了这个问题，因为它具有循环依赖关系。 （登录屏幕重定向到使用此模块的屏幕后崩溃）

还可能值得注意的是，我使用的是通过以下方式生成的离线包：

npx react-native bundle --dev false --entry-file index.js --bundle-output ios/main.jsbundle --platform ios --assets-dest iOS

如何调试此错误或至少了解此错误的来源？有行号我可以看吗？如何在不必完全禁用此模块的情况下解决此问题？

更新：已修复。查看答案。

干净安装节点模块没有帮助，旧线程：Requiring unknown module “undefined” on react-native-maps、Requiring unknown module “undefined” 也没有帮助。

【参考方案1】：

更新：我能够修复它。这个问题根本与 node_modules 无关。

真正的问题：

<Image source=require('./assets/image.png') />

当我为 Release 构建时，图像没有被包含在内。通过手动将图像添加到 xcassets (iOS) 并将该行更改为：

<Image source= uri: 'image'  />
