vueJs引入iview组件库时报错

这是app.vue代码：

<template>
  <div id="App">
    <img src="./assets/logo.png">
   <!-- <router-view/>-->
   <h1>1234364</h1>
    <login-form></login-form>
    <!--<hello-word></hello-word>-->
  </div>
</template>

<script>
    import LoginForm from './components/LoginForm.vue'
    import HelloWorld from './components/HelloWorld.vue'
const RouterConfig = { routes: Routers};
const router = new VueRouter(RouterConfig);
export default{
  name:"App",
  RouterConfig,
  router,
  components: {
    LoginForm
  }
}
  
new Vue({
    el: '#app',
    router: router,
    render: h => h(App)
});
</script>

<style>
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

这是LoginForm.vue代码：

<template>
    <i-form ref="formInline" :model="formInline" :rules="ruleInline" inline>
        <div prop="user">
            <i-input type="text" v-model="formInline.user" placeholder="Username">
                <icon type="ios-person-outline" slot="prepend"></icon>
            </i-input>
        </div>
        <div prop="password">
            <i-input type="password" v-model="formInline.password" placeholder="Password">
                <icon type="ios-locked-outline" slot="prepend"></icon>
            </i-input>
        </div>
        <div>
            <i-button type="primary" @click="handleSubmit('formInline')">登录</i-button>
        </div>
    </i-form >
</template>
<script>
export default {
    name:"LoginForm",
  data () {
    return {
      formInline: {
        user: '',
        password: ''
      },
      ruleInline: {
        user: [
          { required: true, message: '请填写用户名', trigger: 'blur' }
        ],
        password: [
          { required: true, message: '请填写密码', trigger: 'blur' },
          { type: 'string', min: 6, message: '密码长度不能小于6位', trigger: 'blur' }
        ]
      }
    }
  },
  methods: {
    handleSubmit (name) {
      this.$refs[name].validate((valid) => {
        if (valid) {
          this.$Message.success('提交成功!')
        } else {
          this.$Message.error('表单验证失败!')
        }
      })
    }
  }
}
</script>

请问是什么原因，怎么解决？

Answer 1

先安装，然后引用进来

import iview from 'iview'
import Vue from 'vue;
Vue.use(iview)

Answer 2

使用 npm

$ npm install iview --save

import iview from 'iview'

或使用 <script> 全局引用

<script type="text/javascript" src="iview.min.js"></script>

Answer 3

1.CDN引入:

<!-- import Vue.js -->
<script src="//vuejs.org/js/vue.min.js"></script>
<!-- import stylesheet -->
<link rel="stylesheet" href="//unpkg.com/iview/dist/styles/iview.css">
<!-- import iView -->
<script src="//unpkg.com/iview/dist/iview.min.js"></script>

2.如果是用vue-cli搭建的项目可以直接在要使用的组件中通过import导入,分为全量导入和按需导入:
全量导入:import iview from 'iview';
import 'iview/dist/styles/iview.css';//import后面是iview的路径,
3.也可以按需引入;
