vite load the postcss config by postcss-load-config，I think that import cache the file content, so that postcss can not get the new content of it.

[dominikg]

one workaround is to not use postcss-load-config but instead import postcss.config.js in vite config and pass it to css.postcss: https://stackblitz.com/edit/vitejs-vite-uwhqtw?file=postcss.config.js,vite.config.js&terminal=dev

But i don't know if there are things in postcss config that can't be bundled into the vite config and how it would work with dependencies like a browserslist file for autoprefixer...

@PengBoUESTC I noticed that you submitted a fix upstream. Does that mean that if we upgrade postcss-load-config it should also fix this issue?

yes , And I try to update the 'postcss-load-config' dep version of vite packages ，and maybe this need more test

Are there any known workarounds for this issue? I've cleared node_modules and browser cache... I'm still not getting updates in the compiled css.
