备忘录：
windows下面的nvmw和nvm
windows支持的不好了（nvmw无法安装node，后来发现目录结构已经变化了）
还是果断使用ubuntu吧。
几个node不同版本对es6的支持程度
使用es-checker的结果
node v4.4.7
nvm install 4
Passes 29 feature Detections
Your runtime supports 69% of ECMAScript 6node v6.3.1
nvm install 6
Passes 37 feature Detections
Your runtime supports 88% of ECMAScript 6node 7没有正式版本，所以nvm无法安装
注意：nvm install node这条命令已经不支持了
为了加速使用了cnpm
但是cnpm连babel-cli都安装不了
最后还是使用npm安装的
在 ~/.npmrc文件中修改为taobao registry
registry = http://registry.npm.taobao.org
项目测试
mkdir testproject
cd testproject
npm init
npm install webpack babel-cli babel-preset-es2015 babel-preset-stage-3 babel-loader --save-dev
npm install babel-core babel-polyfill --save
vi .babelrc
{
"presets": ["es2015","stage-3"],
"plugins": []
}
为了使用打包工具webpack，需要在在module添加loaders,参考
