1.安装React

安装前的准备，原本是放在后面的，但是怕误导别人所以提到前面了。

如果上面的没有报错了，但是目录是空的话，请创建jspm项目

操作如下:

//1. 创建package.json
npm init

//2. 本地安装jspm
npm install jspm --save-dev

//3.创建config.js
jspm init

//4.安装包
jspm install npm:underscore

//5.安装jquery
jspm install jquery

React Native中文官网

1.1 jspm install react@0.14.0-rc1 安装React的版本;如果指定版本不对的话就，直接下载最新的包: jspm install react

1.2 jspm install react-dom@0.14.0-rc1 安装react-dom的版本,同上:jspm install react

1.3 jspm install semantic-uiUI样式

1.4 jspm install css UI插件

1.5 browser-sync start --server --no-notify --files 'index.html, app/**/*.js'创建一个服务器来监视文件的变化

1.6 npm install webpack -g安装webpack

1.6 npm install -g webpack webpack-dev-server webpack服务

执行:sudo npm i babel-runtime@6 --save-dev

解决的方法是:rm -rf node_modules/,然后就可以了

重新安装就好了:

➜  ~ sudo npm i babel-runtime@6 --save-dev
/Users/x
└─┬ babel-runtime@6.20.0 
  ├── core-js@2.4.1 
  └── regenerator-runtime@0.10.1

安装UI样式:

➜  ~ jspm install semantic-ui
