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。 p>
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":{}} ERROR Invariant Violation: `new NativeEventEmitter()` requires a non-null argument., js engine: hermes at ?anon_0_ (http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false&modulesOnly=false&runModule=true&app=org.reactjs.native.example.ApuntesDelCampo:132800:100) at next (native) at asyncGeneratorStep (http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false&modulesOnly=false&runModule=true&app=org.reactjs.native.example.ApuntesDelCampo:20867:26) at _next (http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false&modulesOnly=false&runModule=true&app=org.reactjs.native.example.ApuntesDelCampo:20886:29) at anonymous (http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false&modulesOnly=false&runModule=true&app=org.reactjs.native.example.ApuntesDelCampo:20891:14) at tryCallTwo (/Users/distiller/react-native/sdks/hermes/build_iphonesimulator/lib/InternalBytecode/InternalBytecode.js:61:9) at doResolve (/Users/distiller/react-native/sdks/hermes/build_iphonesimulator/lib/InternalBytecode/InternalBytecode.js:216:25) at Promise (/Users/distiller/react-native/sdks/hermes/build_iphonesimulator/lib/InternalBytecode/InternalBytecode.js:82:14) at anonymous (http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false&modulesOnly=false&runModule=true&app=org.reactjs.native.example.ApuntesDelCampo:20883:25) at apply (native)
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,

========。 RegisterScreen.js ==================

============。 auth.js。 =============

========。 firebase.js。 ========
import firebase from '@react-native-firebase/app' import '@react-native-firebase/firestore' import '@react-native-firebase/auth' // Configura Firebase const firebaseConfig = { apiKey: "xxxxx", authDomain: "xxxxx", projectId: "cxxxxx", storageBucket: "xxxx", messagingSenderId: "xxxx", appId: "xxxxxx" }; if (!firebase.apps.length) { firebase.initializeApp(firebaseConfig) } const firebaseFirestore = firebase.firestore(); const firebaseAuth = firebase.auth(); export { firebaseFirestore, firebaseAuth }
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:
