使用vue-validator 一直报错 提示 minlength of undefined ？

Question

1. 使用vue-validator，按文档安装，验证required的时候报Cannot read property 'minlength' of undefined，验证minlength的时候Cannot read property 'minlength' of undefined

2. 报错截图

//app.js

import Vue from 'vue'
import VueRouter from 'vue-router'
import VueResource from 'vue-resource'
import VueValidator from 'vue-validator'

import router from './router/router'

Vue.use(VueValidator);

router.start(App, '#app');

<validator name="validator1">
  <form class="form-horizontal" novalidate>
    <div class="form-group">
      <label for="input-1" class="col-sm-2 control-label">{{ $t("creation.orderNo") }}</label>
      <div class="col-sm-10">
        <input type="text" class="form-control" id="input-1" v-model="order_id" placeholder="{{ $t('creation.orderNo') }}" v-validate:order_id="{minlength: 16, maxlength: 128}">
        <span v-show="$validator1.order_id.minlength">Your comment is too short.</span>
      </div>
    </div>
  </form>
</validator>

Answer 1

Answer 2

请问你解决了吗，我也遇到了同样的问题

Answer 3

请问下题主? 这个验证插件应该怎么在router前引用?
