我正在嘗試建立一個使用React Native 創建的應用程序，並且我使用@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 來執行應用程式
我的無知阻止了我繼續這個項目，幾天后就陷入了停滯，因為我試圖使用下面顯示的邏輯在Firebase 中註冊用戶，一個auth.js 檔案（其中包含身份驗證）和firebase.js 檔案firebase 的邏輯。這對我來說是不可能的。
我已經多次更改了這些文件的配置，並且每次更改都無法在此處添加，但已經有好幾次了。
但是我無法讓它註冊新用戶。
我編輯問題 我編輯問題
我根據同事的建議添加了 Podfile。 我還必須說，我已遵循 React Native Firebase 的說明，但如果我進行 AppDelegate.m 和 Podfile 中建議的所有更改，專案就會中斷，並且不會從終端或 Xcode 再次啟動。
錯誤涉及以下文件：
/node_modules/react-native/Libraries/EventEmitter/NativeEventEmitter.js
該應用程式仍在運行，錯誤已更改，但我現在記錄的錯誤如下：

我知道原因可能有多個，這就是我來這裡的原因，因為經過多次嘗試和根據 Stackoverflow 上發現的其他類似問題進行的許多更改後，我找不到解決方法。也許有人會看到我在程式碼中出現的錯誤或可以建議正確的配置。
我不明白 iOS 配置是否會影響它，每當我執行 "pod install" 時，所有依賴項都會再次安裝，並顯示：
[!] 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.
我展示了這些文件，希望您能給我一些想法，以便能夠糾正此問題並繼續，

當您在沒有靜態函式庫的情況下執行 pod install 時，它會拋出錯誤，並且不會實際安裝 Firebase。
停用 Flipper，因為 Flipper 不適用於靜態函式庫：
# 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
在目標「ApuntesDelCampo」內在flags = ...上方加入以下兩個內容：
use_frameworks! :linkage => :static $RNFirebaseAsStaticFramework = true # Flags change depending on the env values. flags = get_default_flags()
也要確保您已將 GoogleService-Info.plist 新增到您的專案中。
現在再次運行pod install，並嘗試安裝應用程式。
