Syntax error in vite.config.js

[parischap]

Using NodeJS 12.5.0.

Just installed a vite vue project on my pc with the following commands :
yarn create @vitejs/app tarteen --template vue
yarn install
yarn dev

And I get the following error during the yarn dev :

failed to load config from C:\Users\JEROME\Documents\MesDeveloppements\SitesInternet\tarteen\vite.config.js
error when starting dev server:
C:\Users\JEROME\Documents\MesDeveloppements\SitesInternet\tarteen\vite.config.js:1
import { defineConfig } from 'vite';
^
