身份验证错误：app._isFirebaseServerApp 不是函数（未定义）

Question

我在主应用程序中遇到这个问题，但正在处理另一个项目。当我单独运行 app.js 中的相关部分时，它会给出相同的错误（就像在其他项目中一样）。我用世博会。还有我的 package.json:

  "main": "node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "web": "expo start --web"
  },
  "dependencies": {

    "@firebase/app": "^0.9.29",

问题

Answer 1

您正在混合使用 Firebase Web Client SDK (

firebase

) 和 React-Native-Firebase (

@react-native-firebase

)。您几乎肯定不想这样做。 这里有一篇文章（披露：我写的）描述了这些差异。

此外，当您安装 Firebase Web Client SDK (

npm i firebase

) 时，您无需安装其子组件（

@firebase/app

、

@firebase/auth

等）

查看该错误消息附带的堆栈跟踪，您应该看到您自己的代码中调用 API 的位置导致了该错误。将来，提供完整的堆栈跟踪而不仅仅是错误消息会更有帮助。对您来说更有用的是跟踪代码中抛出错误的位置，然后与我们分享该代码的片段。
