vue.js - Vuetify v-select 不显示 :items

Question

我想不通。我正在使用 Vuetify 来设置我的页面样式，但出于某种原因，我无法在我的 v-select 选择框中显示数据。数据应该来自数组 marketplaces。我认为这可能是版本问题，但我已经升级了所有内容，但它仍然无法正常工作。我无法让该死的东西显示我的数据!

这是页面:

<template>
    <v-container fluid grid-list-lg class="come_closer">

</script>

<style>

  .chip__content {
    background-color: #68007d !important;

上面的页面是这个页面中的一个组件:

<template>
  <v-app>
    <credential_instructions class="no_background"></credential_instructions>
    <credential_details
      xs12
      class="no_background"
      id="amazon_credentials"
      v-for="(item, index) in components"
      :index="index"
      :key="'fourth' + index "
      >
    </credential_details>
  </v-app>  
</template>

<script>
/*global top*/

import {dataShare} from '../packs/application.js';
import credential_instructions from '../components/credential_instructions.vue';
import credential_details from '../components/credential_details.vue';
import axios from 'axios';

export default {
  data: function() {
    return {
      components: [1],
    };
  },
  components: {
    credential_instructions,
    credential_details
  },
  created() {
    dataShare.$on('addComponent', (data) => {
      this.components.push(data);
    });
    dataShare.$on('removeComponent', (data) => {
      this.components.pop();
    });
  },
  methods: {
    sendToBilling() {
      axios.post('https://new-ship-trimakas.c9users.io/create_billing_plan').then(response => {
        console.log(response.data);
        top.location.href = response.data.url_redirect;
      });
    }
  }
};  

</script>

<style>

.dark-green-button {
  background-color: #43A047 !important;
}

.green-font {

}

.red-font {

}

.full-height .flex{
  display: flex !important; 
}

.full-height .flex > .card{
 flex: 1 1 auto !important; 
}


.textfield-background-beige {
  background-color: #f7f1ec !important;
}

.theme--light .input-group input:disabled {
  color: rgba(0,0,0,.87) !important;
}

.lightbeige {
  background-color: #f1e7df !important;
}

.lightblue {
  background-color: #d9d6e1 !important;
}

.lightpurple {
  background-color: #e9daea !important;
}

.match-to-text-field {
  margin-left: -17px !important;
  height: 46px !important;
  margin-top: 2px !important;
}
</style>

最后这是我的 package.json

{
  "name": "shopify-ship-refactor",
  "version": "1.0.0",
  "description": "Complete Shopify shipping app refactor",
  "main": "index.js",
  "author": "Todd",
  "license": "MIT",
  "dependencies": {
    "@rails/webpacker": "3.5",
    "axios": "^0.18.0",
    "v-clipboard": "^2.0.1",
    "vue": "^2.5.16",
    "vue-loader": "^14.2.2",
    "vue-router": "^3.0.1",
    "vue-template-compiler": "^2.5.17",
    "vuelidate": "^0.7.4",
    "vuetify": "^1.0.19"
  },
  "devDependencies": {
    "webpack-dev-server": "2.11.2"
  }
}

我没有收到任何错误或警告，只是应该填充在选择框中的数据没有。有什么想法吗？

它发生的另一个原因是因为你没有 <v-app></v-app>在你的代码中。我的问题是。重新添加，问题解决。
