// 如想在微信小程序和 H5 端分別引用不同資源

if (process.env.TARO_ENV === 'weapp') {
  require('path/to/weapp/name')
} else if (process.env.TARO_ENV === 'h5') {
  require('path/to/h5/name')

// 同時也可以在 JSX 中使用，決定不同端要加載的組件

render () {
  return (
    <View>
      {process.env.TARO_ENV === 'weapp' && <ScrollViewWeapp />}
      {process.env.TARO_ENV === 'h5' && <ScrollViewH5 />}
