I have a problem in VitePress, I used VantUI, but he throws an error.
Unknown file extension ".css" for C:\Users\woo-m\Desktop\ToTimeMail\node_modules\vant\es\style\base.css
I found the file he mentioned, which is a Less, but VitePress should have built-in support for Less, and should not throw an error.
I also used elementPlus in vitepess, which is fully usable, but when I checked his source code, he did not use less, which may be the reason. But I don't know how to deal with him.
