我正在尝试构建一个使用 React Native 创建的应用程序，并且我使用 @react-native-firebase/app": "^17.5.0", "@react-native-firebase/auth": "^ 17.5.0", "@react-native-firebase/firestore": "^17.5.0",
我使用 npx react-native run-ios 运行应用程序
我的无知阻止了我继续这个项目，几天后就陷入了停滞，因为我试图使用下面显示的逻辑在 Firebase 中注册用户，一个 auth.js 文件（其中包含身份验证）和 firebase.js 文件firebase 的逻辑。这对我来说是不可能的。
我已经多次更改了这些文件的配置，并且每次更改都无法在此处添加，但已经有好几次了。
但是我无法让它注册新用户。
我编辑问题 我编辑问题
我根据同事的建议添加了 Podfile。 我还必须说，我已遵循 React Native Firebase 的说明，但如果我进行 AppDelegate.m 和 Podfile 中建议的所有更改，项目就会中断，并且不会从终端或 Xcode 再次启动。
错误涉及以下文件：
/node_modules/react-native/Libraries/EventEmitter/NativeEventEmitter.js
该应用程序仍在运行，错误已更改，但我现在记录的错误如下：
LOG Running "Cositas enter code here" with {"rootTag":1,"initialProps":{}}

我知道原因可能有多个，这就是我来这里的原因，因为经过多次尝试和根据 Stackoverflow 上发现的其他类似问题进行的许多更改后，我找不到解决方法。也许有人会看到我在代码中出现的错误或者可以建议正确的配置。
我不明白 iOS 配置是否会影响它，每当我运行 "pod install" 时，所有依赖项都会再次安装，并显示：
[!] The following Swift pods cannot yet be integrated as static libraries:
The Swift pod `FirebaseCoreInternal` depends upon `GoogleUtilities`, which does not define modules. To opt into those targets generating module maps (which is necessary to import them from Swift when building as static libraries), you may set `use_modular_headers!` globally in your Podfile, or specify `:modular_headers => true` for particular dependencies.
我展示了这些文件，希望您能给我一些想法，以便能够纠正此问题并继续，

当您在没有静态库的情况下运行 pod install 时，它会抛出错误，并且不会实际安装 Firebase。
禁用 Flipper，因为 Flipper 不适用于静态库：
# Note that if you have use_frameworks! enabled, Flipper will not work if enabled # :flipper_configuration => flipper_config, <-- comment this line # An absolute path to your application root
在目标“ApuntesDelCampo”内在flags = ...上方添加以下两个内容：
use_frameworks! :linkage => :static $RNFirebaseAsStaticFramework = true # Flags change depending on the env values. flags = get_default_flags()
还要确保您已将 GoogleService-Info.plist 添加到您的项目中。
现在再次运行pod install，并尝试安装应用程序。
