我正在从RN 0.55.3升级到0.57.0（手动）。
运行react-native run-ios或react-native run-android之后，我现在收到错误消息：
error: bundling failed: Error: While trying to resolve module `react-native-firebase`
我已经尝试过重新运行react-native link react-native-firebase（per this post）以及删除node_modules并重新运行yarn都没有用。
完整的错误报告：
error: bundling failed: Error: While trying to resolve module `react-native-firebase` from file `MyApp/src/screens/StarterPage.js`, the package `MyApp/node_modules/react-native-firebase/package.json` was successfully found. However, this package itself specifies a `main` module field that could not be resolved (`MyApp/node_modules/react-native-firebase/dist/index.js`. Indeed, none of these files exist:
* `MyApp/node_modules/react-native-firebase/dist/index.js(.native||.ios.js|.native.js|.js|.ios.json|.native.json|.json|.ios.ts|.native.ts|.ts|.ios.tsx|.native.tsx|.tsx)`
* `MyApp/node_modules/react-native-firebase/dist/index.js/index(.native||.ios.js|.native.js|.js|.ios.json|.native.json|.json|.ios.ts|.native.ts|.ts|.ios.tsx|.native.tsx|.tsx)`

我检查了所有这些文件，并将它们放在node_modules/react-native-firebase中。例如，/dist/index.js是：
import firebase from './modules/core/firebase';
export default firebase;
export * from './modules/core/firebase';
/*
* Export App types
*/

我希望我的应用程序可以在模拟器（iOS）或手机（Android）上运行。

您是否尝试过重置守望者和Metro Bundler缓存？
watchman watch-del-all
react-native start --reset-cache
