嘿，你们真的在这里挣扎。

我正在尝试在我的 Next.js 应用程序中使用 firebase，专门用于 api。当我在本地构建生产和本地开发时，它运行良好。但是，一旦我在 vercel 平台上部署到生产环境，我就会得到一个500 - Internal Server Error. 我已经能够将错误缩小到它是由使用引起的，await getDocs(q)但不确定如何修复它。

本质上，我正在尝试使用来自 firestore 的数据进行动态 api 路由。

firebase.js：

// Import the functions you need from the SDKs you need
import { initializeApp } from "firebase/app";
import { getFirestore } from "firebase/firestore";
import { getStorage } from "firebase/storage";

// TODO: Add SDKs for Firebase products that you want to use
// https://firebase.google.com/docs/web/setup#available-libraries

// Your web app's Firebase configuration
// For Firebase JS SDK v7.20.0 and later, measurementId is optional
const firebaseConfig = {
  apiKey: "<REDACTED_FOR_STACKOVERFLOW>",
  authDomain: "<REDACTED_FOR_STACKOVERFLOW>",
  databaseURL: "<REDACTED_FOR_STACKOVERFLOW>",
  projectId: "<REDACTED_FOR_STACKOVERFLOW>",
  storageBucket: "<REDACTED_FOR_STACKOVERFLOW>",
  messagingSenderId: "<REDACTED_FOR_STACKOVERFLOW>",
  appId: "<REDACTED_FOR_STACKOVERFLOW>",
  measurementId: "<REDACTED_FOR_STACKOVERFLOW>"
};

// Initialize Firebase
const app = initializeApp(firebaseConfig);
// Database
const db = getFirestore();
// Storage
const storage = getStorage(app)

export {
  app,
  storage,
  db
}

/api/users/[name].js：

import { db } from './firebase.js'

export default async function handler(req, res) {
  try {
    const { name } = req.query
    let users = []
    const q = query(collection(db, "users"), where("name", "==", name))
    const querySnapshot = await getDocs(q)
    if (querySnapshot.empty) {
      res.status(404).json({error: "Document does not exist."})
    } else {
      querySnapshot.forEach((doc) => {
        users.push(doc.data())
      })
      res.status(200).json(users)
    }
  } catch(err) {
    res.status(404).json({error: err})
  }
}

package.json：

{
  "name": "app-frontend",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "dev": "next dev",
    "build": "next build",

    "eslint-config-next": "11.0.1",
    "postcss": "^8.3.5",
    "tailwindcss": "^2.2.4"
  }
}

服务器端的错误是这样开始的： @firebase/firestore: Firestore (9.5.0): INTERNAL UNHANDLED ERROR: Error: ENOENT: no such file or directory, open '/var/task/node_modules/@firebase/firestore/dist/src/protos/google/firestore/v1/firestore.proto'

将 firebase 降级到 9.4.0 为我解决了确切的问题。我不确定这是否是一个好的修复，但它有效。

为此，如果您使用handler函数 ingetServerSideProps或其他函数 in index.js，请尝试使用以下代码：

const q = query(collection(getFirestore(app), "users"), where("name", "==", name))

这对我有用。谢谢

问题是依赖项以某种方式安装在本地包中node_modules，但未在 package.json 上定义。

您需要在 package.json 上定义它，以便在构建阶段安装它

在项目文件夹上，打开终端并安装它，以便将其添加到包中：

npm install --save firebase
