部署到 Firebase 托管后我的 React 项目无法正常工作

2018-12-11

reactjs firebase firebase-hosting

我按照此网站的说明操作，并且已经在尝试使用一个空的 create-react-app 项目，并且它运行良好

但是当我在部署过程完成后尝试使用现有项目时，它说

Firebase Hosting 设置已完成 您看到此信息是因为您已成功设置 Firebase Hosting。现在是时候去构建一些非凡的东西了！

所以我非常好奇我错过了什么

这是 package.json 

{
  "name": "iplace",
  "version": "0.1.0",
  "private": false,
  "dependencies": {
    "node-sass": "^4.10.0",
    "react": "^16.6.3",
    "react-dom": "^16.6.3",
    "react-router": "^4.3.1",
    "react-router-dom": "^4.3.1",
    "react-scripts": "2.1.1"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ]
}

firebase.json 

{
  "hosting": {
    "public": "build",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "rewrites": [
      {
        "source": "**",
        "destination": "/index.html"
      }
    ]
  }
}

我已经执行 firebase init (change public-> build) > npm run build > firebase deploy

这是项目结构

这是项目结构

这是 index.html 文件（我很好奇为什么 index.html 仍然有欢迎使用 firebase 的措辞...）

第一个任务

您需要在 public 文件夹的 index.html 中用以下代码替换此代码： 

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <link rel="icon" href="%PUBLIC_URL%/favicon.ico" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />
    <meta name="theme-color" content="#000000" />
    <meta
      name="description"
      content="Web Chat Application created using professional technologies" 
    />
    <link rel="apple-touch-icon" href="%PUBLIC_URL%/logo192.png" />
    <!--
      manifest.json provides metadata used when your web app is installed on a
      user's mobile device or desktop. See https://developers.google.com/web/fundamentals/web-app-manifest/
    -->
    <link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
    <!--
      Notice the use of %PUBLIC_URL% in the tags above.
      It will be replaced with the URL of the `public` folder during the build.
      Only files inside the `public` folder can be referenced from the HTML.

      Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
      work correctly both with client-side routing and a non-root public URL.
      Learn how to configure a non-root public URL by running `npm run build`.

第二个任务：

  • 删除 .firebaserc 文件。
  • 删除 firebase.json 文件。

第三个任务：

  • 删除“.firebase”文件夹。
  • 删除“build”文件夹。

第四个任务：

运行命令：firebase init 它会询问： 您要为此目录设置哪些 Firebase 功能？ 选择：托管：为 Firebase 托管配置文件并（可选）设置 GitHub Action 部署

然后选择： 请选择一个选项：使用现有项目 然后选择您的项目名称

第五个任务：

（输入您要初始化应用程序的文件夹名称。如果是 React 应用程序，则为 build。） 您想使用什么作为您的公共目录？ build

第六个任务：

（在单页应用程序中选择“是”） 配置为单页应用程序（将所有 URL 重写为 /index.html）？ 是

第七个任务：

使用 GitHub 设置自动构建和部署？否

第八项任务：

（运行此命令） npm run build /yarn build

最后一项任务：

（运行此命令） firebase deploy

就我而言，这就是它的工作原理。

您已使用 firebase 在初始化期间创建的默认 index.html 覆盖了您的 index.html。

修复方法：

  1. 删除当前 index.html
  2. 获取您的原始 index.html
  3. 再次运行 firebase 初始化。
  4. 当它要求您覆盖“index.html”时 - 说“否”。

我遇到了同样的问题，而且由于部署，这很令人困惑。原来我必须确保运行 

npm run build
firebase deploy

然后等待几分钟才能显示网站。这假设您没有修改 react index.html 文件
