我正在尝试在 expo 托管的 react-native 应用程序中读取和写入 firestore,使用 firebase 的身份验证和 firebase 的存储。
完全错误:
While trying to resolve module `firebase` from file `C:\Users\joshu\Desktop\VSProjects\VolleyballConnect\firebase.js`, the package `C:\Users\joshu\Desktop\VSProjects\VolleyballConnect\node_modules\firebase\package.json` was successfully found. However, this package itself specifies a `main` module field that could not be resolved (`C:\Users\joshu\Desktop\VSProjects\VolleyballConnect\node_modules\firebase\index`. Indeed, none of these files exist:
* C:\Users\joshu\Desktop\VSProjects\VolleyballConnect\node_modules\firebase\index(.native|.android.ts|.native.ts|.ts|.android.tsx|.native.tsx|.tsx|.android.js|.native.js|.js|.android.jsx|.native.jsx|.jsx|.android.json|.native.json|.json)
* C:\Users\joshu\Desktop\VSProjects\VolleyballConnect\node_modules\firebase\index\index(.native|.android.ts|.native.ts|.ts|.android.tsx|.native.tsx|.tsx|.android.js|.native.js|.js|.android.jsx|.native.jsx|.jsx|.android.json|.native.json|.json)
我的 Firebase 配置文件:import firebase from "firebase";
import { initializeApp } from "firebase/app";
import "firebase/firestore";
import "firebase/auth";
import "firebase/storage";
// I'm using the example key here, I have the correct config
const firebaseConfig = {
apiKey: "api-key",
authDomain: "project-id.firebaseapp.com",
databaseURL: "https://project-id.firebaseio.com",
projectId: "project-id",
storageBucket: "project-id.appspot.com",
messagingSenderId: "sender-id",
appId: "app-id",
measurementId: "G-measurement-id",
};
if (firebase.apps.length === 0) {
initializeApp(firebaseConfig);
}
const db = firebase.firestore();
const auth = firebase.auth();
const storage = firebase.storage();
export { db, auth, storage };
我安装了firebase
包装:expo install firebase
任何帮助将不胜感激。谢谢!
最佳答案
为了减小应用程序的大小,firebase SDK (v9.0.0) 变得模块化。您不能再像以前那样在 v8 上执行 import 语句。
你有两个选择。
这个:
import firebase from 'firebase/app';
import 'firebase/auth';
import 'firebase/firestore';
应改为:// v9 compat packages are API compatible with v8 code
import firebase from 'firebase/compat/app';
import 'firebase/compat/auth';
import 'firebase/compat/firestore';
由此:
import firebase from "firebase/compat/app";
import "firebase/compat/auth";
const auth = firebase.auth();
auth.onAuthStateChanged(user => {
// Check for user status
});
对此:import { getAuth, onAuthStateChanged } from "firebase/auth";
const auth = getAuth(firebaseApp);
onAuthStateChanged(auth, user => {
// Check for user status
});
你一定要检查documentation
关于javascript - `Firebase` 包被成功找到。但是,这个包本身指定了一个无法解析的 `main` 模块字段,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/69814654/
