Creat React App deploy on GitHub

转 https://blog.csdn.net/sinat_27088253/article/details/89640479

在将本地的react项目部署到GitHub上时，除了官方文档上介绍的那几步外，可能还会出现下面的两个错误。

Failed to get remote.origin.url (task must either be run in a git repository with a configured origin remote or must be configured with the “repo” option).

解决办法：没有和远程仓库链接。可以用git remote来查看一下是否为空，若为空，需要用git remote add origin ...来添加远程仓库

fatal: A branch named ‘gh-pages’ already exists.

解决办法：缓存中已经存在‘gh-pages’分支。解决办法需要将分支从缓存中删除，可以使用rm -rf node_modules/gh-pages/.cache，也可以直接去删除node_modules/gh-pages/.cache文件夹

实践记录：

1.修改package.json,如下红色标注的内容

{
  "name": "yarn-app",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "antd": "^3.26.5",
    "react": "^16.12.0",
    "react-dom": "^16.12.0",
    "react-native-cli": "^2.0.1",
    "react-scripts": "3.3.0"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject",
    "predeploy": "yarn build",
    "deploy": "gh-pages -b master -d build"
  },
  "homepage": "https://<username>.github.io/<project>",
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
  "devDependencies": {
    "gh-pages": "^2.1.1"
  }
}
同时安装gh-pages依赖包,运行如下命令
yarn add gh-pages -g


2.运行yarn build,生成发布build文件目录

3. 在当前app根目录下运行
　　git init
　　git add build
　　git commit -m '注解内容'
3.连接远程仓库
　　git remote add origin https://github.com/xxx/yyy.git
4.运行 yarn add --dev gh-pages，准备创建gh-pages分支


5.运行yarn run deploy命令

>yarn run deploy
然后根据提示需要填写github账号和登录密码即可自动

经过以下步骤就可系统已经把build目录下所有文件发布到gh-pages分支下了，如下图：
