+If you don't have an `env.d.ts` file, you can create one and add the unplugin-vue-router types to it _or_ you can add them to the `types` property in your `tsconfig.json`:

+::: code-group
+
+```json [tsconfig.json]
+{

 Instead of importing from `vue-router`, you should import from `vue-router/auto`.
