我无法弄清楚这一点。我正在使用 Vuetify 来设置我的页面样式，但由于某种原因，我无法将数据显示在我的v-select选择框中。数据应该来自数组marketplaces。我以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。我无法让冷冰冰的东西显示我的数据！
这是页面：

我没有收到任何错误或警告，它只是应该在选择框中填充的数据不是。 有什么想法吗？
它发生的另一个原因是因为你的代码中没有<v-app></v-app>。 我的问题是这样。 再次添加它，解决了问题。
有关详细信息，请参阅Sumurai8在"V-menu的Vuetify问题"中的回答。
我相信，由于您要将对象数组传递给v-select组件，因此您需要告诉它要显示为文本的内容，并将其设置为值。
所以在你的情况下，它应该看起来像这样：
<v-select
required
:items="marketplaces"
item-text="text"
item-value="value"
label="Select your Amazon Marketplace"
:error-messages="marketplaceErrors"
v-model="selected_marketplace"
color="purple darken-3"
prepend-icon="map"
@input="$v.selected_marketplace.$touch()"
@blur="$v.selected_marketplace.$touch()"
></v-select>
他们在文档中有一个关于此的部分，但它在该页面上有点埋藏： 自定义项目和文本值
希望这有帮助。
为了将来参考，我在处理的代码库中也遇到了类似的问题，似乎组件"v-select"被一个名为 vue-select 的库覆盖了。
在安装文档中，他们展示了如何像这样注册那里的组件：
Vue.component('v-select', vSelect)
哇，这是一场噩梦。只花了大约一天的时间就找到了解决方案。希望如果您看到此内容，它也可以成为您的解决方案。
部分问题是我还收到了vue is installed twice错误和各种其他警告。
所以我找到了这篇文章： Vuetify bug
那么这篇文章：Webpacker配置更改
最后是这个： 网络包装程序自定义.js
这就是最终的结果。我在/config/webpack/custom.js中创建了custom.js，它看起来像这样：
module.exports = {
resolve: {
alias: {
vue$: 'vue/dist/vue.esm.js'
}
}
}
我还必须将environment.js更新为：
const { environment } = require('@rails/webpacker')
const vue = require('./loaders/vue')
const customConfig = require('./custom')
environment.config.set('resolve.extensions', ['.foo', '.bar'])
environment.config.set('output.filename', '[name].js')
// Merge custom config
environment.config.merge(customConfig)
// Delete a property
environment.config.delete('output.chunkFilename')
environment.loaders.append('vue', vue)
module.exports = environment
这两个配置文件解决了我的问题。同样作为参考，我正在运行Vuetify 1.2.1和Vue 2.5.17以及Rails和Ruby。
我面临着同样的问题。我用<v-app> </v-app>包装我的应用程序。我可以解决这个问题
请记住在 v-select 中使用以下方法：
item-text="SomeName">
item-value="SomeID">
由于我的解决方案是更改组件的名称。 我猜该组件与 vuetify 冲突，因为具有相同的名称。
Vue.component('v-selector', vSelect)
<v-selector :options="['Canada', 'United States']"></v-selector>
类似的东西。
你应该导入这一行
import vSelect from 'vue-select';
在要使用 v-select 的文件中
