We want to replace "webpack" with "vite", but our project is relatively large, so we can't upgrade "vue2" to "vue3". After trying according to the example, we find that there is a problem in reading stylus. How can we solve it

The components are internal to us. There is no problem using "webpack" parsing.
How do I configure it“ vite.config.js ”At present, the document is not very clear?
