javascript - 类型错误 : Cannot read property 'rtl' of undefined

Question

我正在尝试构建一个 vuejs(使用 vuetify 2.1.4)组件库，并通过 npm 链接将其导入本地的另一个应用程序，但我不断收到多个错误提示

TypeError: Cannot read property 'rtl' of undefined

或

TypeError: Cannot read property 'lang' of undefined

注意。称为 Test 的测试基本组件可以正常工作，因为它不包含来自 Vuetify 的任何内容。

这是截图

App1(正在构建的应用)

import Agent from '@/components/Agent'
import Test from '@/components/Test'

const AgentLibrary = {
  install(Vue, options = {}) {

  }
}

export default AgentLibrary

App2(正在导入 App1 的应用)

主要.js

import Vue from 'vue'
import App from './App.vue'

Vue.config.productionTip = false

import vuetify from './plugins/vuetify';

import "AgentComponents"

console.log(AgentComponents.default)

Vue.use(AgentComponents.default)

new Vue({
     vuetify,
  render: h => h(App)
}).$mount('#app')

应用.vue

<template>
  <v-app>
      <Agent/>
  </v-app>
</template>

<script>

export default {
  name: 'App',
  components: {
  },
  data: () => ({
    //
  }),
};
</script>

插件/vuetify.js

import Vue from 'vue';
import Vuetify from 'vuetify/lib';

Vue.use(Vuetify);

export default new Vuetify({
  icons: {
    iconfont: 'mdi',
  },
});

我希望在 App1 中看到我的 Agent 组件在构建并导入 App2 时正常显示和工作(运行 npm run serve)，没有任何错误。

我的 chrome 浏览器中显示的错误如下所示:运行时，我在 Chrome 控制台中看到如下所示的多个错误

Answer 1

这是因为 --inline-vue 标志而发生的。它告诉 Vue 创建自己的实例并将其捆绑在您的库中(有关详细说明，请参阅 here)。

当你在代码中实例化 Vue 时，你会做类似 this 的事情。 :

new Vue({
    vuetify,
    ...
});

但是，当 Vue 为您执行此操作时，它不会将 vuetify 插件作为选项传递给 Vue 构造函数。

一种解决方案是删除 --inline-vue 标志。但是，我不确定这是否与您的情况相关。

我在 Vuetify 存储库上打开了一个 Github 问题/问题，https://github.com/vuetifyjs/vuetify/issues/10198 ，询问他们是否计划支持此标志。
