Property '$const' does not exist on type 'ComponentPublicInstance<{}, {}, {}, {}, {}, EmitsOptions, {}, {}, false, ComponentOptionsBase<{}, {}, {}, {}, {}, ComponentOptionsMixin, ComponentOptionsMixin, EmitsOptions, string, {}>>'.Vetur(2339)

import { createApp } from "vue";
import App from "./App.vue";

app.config.globalProperties.$const = Object.freeze(constants);

app.use(store);

app.mount("#app");

成分

<script lang="ts">
import { defineComponent } from "vue";

export default defineComponent({
  name: "Header", …
