我有一个用于服务器和前端的 Github 存储库。目录结构如下：

root
  |- frontend
  |- server (Express App)

GitHub 操作：

root
  |- frontend
  |- server (Express App)

我只有一项工作来构建 Express 服务器（还不是前端），所以我working-directory将./server. 但是，我仍然收到错误：

Dependencies lock file is not found in /home/{username}/runners.../repository_name. Supported file patterns: package-lock.json,yarn.lock

所以显然它并没有试图跑进去.../reposirtoy_name/server。

我只是想在单个 Github 操作中构建服务器和前端。

我正在学习如何在 React 应用程序中使用 firebase 身份验证，并且遇到了这个问题。有人可以帮助我吗？

我已经使用 npm 安装了 firebase。这是我的 firebase.js 文件。

import { initializeApp } from "firebase/app";
import 'firebase/auth'

const firebaseConfig = {
apiKey: "AIzaSyA_89k1bt6Z2_1lVLb_Vwn5OL9_GgTNQEQ",
authDomain: "auth-development-59396.firebaseapp.com",
projectId: "auth-development-59396",
storageBucket: "auth-development-59396.appspot.com",
messagingSenderId: "1003786595756",
appId: "1:1003786595756:web:fa93ae00e49a4c04c49e09"

};

const app = initializeApp(firebaseConfig);

export const auth = app.auth()
export default app

这是依赖项 package.json 文件。

"dependencies": {
"@testing-library/jest-dom": "^5.14.1",
"@testing-library/react": "^11.2.7",
"@testing-library/user-event": "^12.8.3",
"bootstrap": "^5.1.1",
"firebase": "^9.0.2",
"react": "^17.0.2",
"react-bootstrap": "^1.6.3",
"react-dom": "^17.0.2",
"react-scripts": "4.0.3",
"web-vitals": "^1.1.2"
 }

我尝试 firebase 9 版本持久登录：

setPersistence(auth, firebaseApp.auth.Persistence.LOCAL).then( async() => {
  // login
}).catch((e) => {
  this.error = e.message
})

显示错误：

Uncaught TypeError: Cannot read property 'Persistence' of undefined

有什么线索吗？

如何where()使用 Firebase Modular SDK (v9) 执行带有条件子句的查询？

名称空间版本 (v8) 中的示例查询：

const status = "live"
const publishedAfter = 1630607348811

let q = firebase.firestore().collection("articles")

// filters selected by users
if (status) q = q.where("status", "==", "live")
if (publishedAfter) q = q.where("publishedAt", ">", publishedAfter)

const qSnapshot = await q.get()

我正在尝试访问我的 firestore 集合中的所有文档

  const app = initializeApp(firebaseConfig);
  const db = getFirestore(app);


  async function getTodos() {
        try {
            const todoRef = collection(db, 'todos');
            let allTodos = await getDoc(todoRef);
            console.log(allTodos)

        } catch (err) {
            console.log(err)
        }
    }

但它抛出了这个错误 FirebaseError: Expected type 'Tc', but it was: a custom Ac object

我试图用谷歌搜索它几次，但没有运气，基本上，当页面加载时，因为密码处于自动保存状态，v-text-field 不理解它并在标签前面呈现密码内容，是否存在任何解决方法或修复？这是一个ss：

登录组件：

  <div>
    <v-card class="elevation-12">
      <v-toolbar color="primary" dark flat>
        <v-toolbar-title>Login</v-toolbar-title>

如何执行读写操作以及从 Firebase 实时数据库查询数据，v8 中的传统语法如下：

const snapshot = await firebase.database().ref("/path").once("value")

考虑样本数据：

{
  "users" : {
    "user1" : {
      "age" : 34,
      "name" : "user1"
    },
    "user2" : {
      "age" : 23,
      "name" : "user2"
    },
    "user345" : {
      "age" : 19,
      "name" : "user345"
    },
    "user4" : {
      "age" : 15,
      "name" : "user4"
    },
    "user56" : {
      "age" : 45,
      "name" : "user56"
    },
    "user9435" : {
      "age" : 8,
      "name" : "user9435"
    }
  }
}

另外你会如何使用这些方法equalTo(), orderByChild(), etc …

我在尝试运行 next.js 应用程序时遇到此错误。我尝试了很多方法但无法解决这个问题。我正在使用 firebase 9.0.1

我刚刚设置了我的应用程序并集成了应用程序检查，代码如下所示

import { initializeApp, getApps } from "firebase/app";
import { getAuth, } from "firebase/auth";
import { getAnalytics } from "firebase/analytics";
import {  getFirestore } from "firebase/firestore";

let app;

if (!getApps().length) {
    app = initializeApp({
        apiKey: process.env.NEXT_PUBLIC_API_KEY,
        authDomain: process.env.NEXT_PUBLIC_AUTH_DOMAIN,
        projectId: process.env.NEXT_PUBLIC_PROJECT_ID,
        storageBucket: process.env.NEXT_PUBLIC_STORAGE_BUCKET,
        databaseURL: process.env.NEXT_PUBLIC_DATABASE_URL,
        messagingSenderId: process.env.NEXT_PUBLIC_MESSAGING_ID,
        appId: process.env.NEXT_PUBLIC_APP_ID,
    });
}
   async function initialize() {
    const { initializeApp } = require("firebase/app");
    const { initializeAppCheck, ReCaptchaV3Provider } = require("firebase/app-check");
  
    const app = initializeApp({
        apiKey: process.env.NEXT_PUBLIC_API_KEY,

我的 Discord 机器人没有向使用该命令的用户添加角色。

我的代码：

if (userCmd.toLowerCase() === `${prefix}verify`) {
  if (message.member.roles.cache.find(role => role.name === 'Rookie' && message.channel.id === '71xxxxxxxxxxx10')) {
  const rookieRole = message.member.guild.roles.cache.find(role => role.name === 'Rookie')
  const proRole = message.member.guild.roles.cache.find(role => role.name === 'Pro')

  try {
    if (message.guild.me.permissions.missing('MANAGE_ROLES')) return message.reply('I\'m missing permissions.');
    if (message.author.id === message.guild.ownerID) return message.reply('I can\'t change your ROLE.');

    message.member.roles.add(proRole)
  } catch(err) {
    console.error(err);
  }
}

我尝试了一切可能的方法：删除并再次添加具有所有权限的机器人，将机器人角色移动到角色层次结构的顶部等。

DiscordAPIError: Missing Permissions

编辑： 无缘无故，使用只message.member.roles.add(proRole)让我的机器人工作：v
