如何使用“VueI18n”和“vue2.0”？`新的VueI18n({..})‘report’没有构造标志‘error

Question

我跟踪了安装指南，但在Vue.use(VueI18n);和const i18n = new VueI18n({...});上出现了错误。

Vue.use(VueI18n)报告

No overload matches this call.
  Overload 1 of 2, '(plugin: PluginObject<unknown> | PluginFunction<unknown>, options?: unknown): VueConstructor<Vue>', gave the following error.
    Argument of type 'typeof import(".../node_modules/vue-i18n/dist/vue-i18n")' is not assignable to parameter of type 'PluginObject<unknown> | PluginFunction<unknown>'.
      Property 'install' is missing in type 'typeof import(".../node_modules/vue-i18n/dist/vue-i18n")' but required in type 'PluginObject<unknown>'.
  Overload 2 of 2, '(plugin: PluginObject<any> | PluginFunction<any>, ...options: any[]): VueConstructor<Vue>', gave the following error.
    Argument of type 'typeof import(".../node_modules/vue-i18n/dist/vue-i18n")' is not assignable to parameter of type 'PluginObject<any> | PluginFunction<any>'.
      Property 'install' is missing in type 'typeof import(".../node_modules/vue-i18n/dist/vue-i18n")' but required in type 'PluginObject<any>'.
    12 | import VueI18n from "vue-i18n";
    13 | 
  > 14 | Vue.use(VueI18n);

和const i18n = new VueI18n({...});报告

This expression is not constructable.
  Type 'typeof import(".../node_modules/vue-i18n/dist/vue-i18n")' has no construct signatures.

这是我的Vue实例。

new Vue({
  vuetify,
  router,
  i18n,
  render: (h) => h(App),
}).$mount("#app");

Answer 1

它连接您使用的Vue version 2，尝试通过键入以下命令安装兼容版本的VueI18n：

npm安装vue-i18n@8 -保存
