weex的picker.pick()真机调试总是报错！！在playground上却没事！！

Question

const picker = weex.requireModule('picker')
  export default {
    data: {
      target: 'World'
    },
    methods: {
      update() {
        picker.pick({
          index:'1',
          items:['a','b','c']
        }, res => {
          if (res.result === 'success') {
            this.target = res.data
          }
        })
      }
    }
  }

难道真机时的sdk和playground的sdk不同？
还有在一个页面中使用2个pick的时候,就会出现只有一个能使用，另外一个就没用了！！

解决了，链接描述
还是属于伸手党，但是weex这样搞，真的让人感到很无语，应该来说这问题出了半年时间了，解决方案也有了，但是官方还是没有修复，这些无语
