(alias) const Demo: VueConstructor<Vue<Record<string, any>, Record<string, any>, never, never, (event: string, ...args: any[]) => Vue>>

I want to use ts, vue2 and vue-class-component to develop a set of my own UI library, when I create a new demo, `

` `import { VueConstructor } from 'vue'; import Demo from './src/main.vue'; (Demo).install = (app: VueConstructor) => { app.component(Demo.name, Demo); } export default Demo; ` At this point I want to use it locally, test-ui/examples/main.ts `import Vue from 'vue' import App from './App.vue' import router from './router' import store from './store' import '../components/css/demo.scss'; import Demo from '../components/lib/demo/src/index'; Vue.use(Demo); Vue.config.productionTip = false new Vue({ router, store, render: h => h(App) }).$mount('#app')` Vue.use(Demo); error: `(alias) const Demo: VueConstructor, Record, never, never, (event: string, ...args: any[]) => Vue>> import Demo No overload matches this call. Overload 1 of 2, '(plugin: PluginObject | PluginFunction, options?: unknown): VueConstructor, Record, never, never, (event: string, ...args: any[]) => Vue<...>>>', gave the following error.

I hope you can help me. Thank you very much!
