學習ReactNative筆記三 __React基礎
★★★筆記時間- 2017-1-11 ★★★
1.安裝React
安裝前的准備，原本是放在后面的，但是怕誤導別人所以提到前面了。
如果上面的沒有報錯了，但是目錄是空的話，請創建jspm項目
操作如下:
//1. 創建package.json
npm init
//2. 本地安裝jspm
npm install jspm --save-dev
//3.創建config.js
jspm init
//4.安裝包
jspm install npm:underscore
//5.安裝jquery
jspm install jquery
React Native中文官網
1.1 jspm install react@0.14.0-rc1 安裝React的版本;如果指定版本不對的話就，直接下載最新的包: jspm install react
1.2 jspm install react-dom@0.14.0-rc1 安裝react-dom的版本,同上:jspm install react
1.3 jspm install semantic-uiUI樣式
1.4 jspm install css UI插件
1.5 browser-sync start --server --no-notify --files 'index.html, app/**/*.js'創建一個服務器來監視文件的變化
1.6 npm install webpack -g安裝webpack
1.6 npm install -g webpack webpack-dev-server webpack服務
執行:sudo npm i babel-runtime@6 --save-dev

解決的方法是:rm -rf node_modules/,然后就可以了
重新安裝就好了:
➜ ~ sudo npm i babel-runtime@6 --save-dev

安裝UI樣式:
➜ ~ jspm install semantic-ui
warn Running jspm globally, it is advisable to locally install jspm via npm install jspm --save-dev.
Updating registry cache...
Looking up github:Semantic-Org/Semantic-UI
Looking up npm:jquery
Looking up github:systemjs/plugin-css
ok Up to date - semantic-ui as github:Semantic-Org/Semantic-UI@^2.2.7 (2.2.7)
