Q： Using removed Babel 5 option: .modules

Using removed Babel 5 option: .modules - Use the corresponding module transform plugin in the `plugins` option. 

A：添加.babelrc配置文件

{
    "presets": [
        [
            "es2015", {"modules": false, "loose": true}
        ],
        ["stage-2"]
    ],
    "plugins": [
        ["transform-runtime"]
    ],
    "comments": false
}
