Can't find ts module. vue?

Question

typescript

Hello, there was an error about types in TS:

property '$error' does not exist on type 'CombinedVueInstance<Vue, { email: string; password: string; }, { onSubmit(): void; }, unknown, Readonly<Record

, it seems to no longer swear, but for some reason it cannot find the module, although the error about types has disappeared. And I will be very grateful if you send me some articles, guides, etc. about using ts together with vue, where everything is written in detail about everything (documentation is not enough).

Mistake:

Failed to compile.

./src/main.ts
Module not found: Error: Can't resolve './token-service' in 'D:\__my_prog\vue\crm\src'

token-service.d.ts:

import Vue from 'vue'
import TokenService from '../path/to/token-service'

declare module 'vue/types/vue' {
  interface Vue {
    $message(html: string) : any 
    $error(html: string) : any 
  }
}

message.plugin.ts:

import M from 'materialize-css'

export default {
  install(Vue, options) {
    Vue.prototype.$message = function (html: string): any {
      M.toast({html})
    }

    Vue.prototype.$error = function(html: string): any {
      M.toast({html: `[Ошибка]: ${html}`})
    }
  }
}

main.ts:

import Vue from "vue";
import Vuelidate from 'vuelidate'
import App from "./App.vue";
import "./registerServiceWorker";
import router from "./router";
import store from "./store";
import dateFilter from "./filters/date.filter";
import messagePlugin from "./utils/message.plugin"
import './token-service'


Vue.config.productionTip = false;

Vue.use(messagePlugin)
Vue.use(Vuelidate as any)
Vue.filter('date', dateFilter)

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