url() pointing to asset file within stylus

[Alinex]

<style lang="stylus" scoped>
  main
    background: url(~assets/background.jpg) no-repeat center center fixed
</style>

This gives me the following error:

Module build failed: Error: /home/alex/github/node-admin-client/src/pages/index.vue:14:20   10| </template>
   12| <style lang="stylus" scoped>
   13|   main { 
   14|     background: url(~assets/background.jpg) no-repeat center center fixed;
--------------------------^   
TypeError: expected unit, but got ident:assets 

What can I do to fix this, using the same as CSS works.

Can anybody help? I made an example here https://codepen.io/anon/pen/GxvYEJ

With simple quote for the url, I think it will be ok:

<style lang="stylus" scoped>
main
  background: url('~assets/background.jpg') no-repeat center center fixed
</style>

Thanks, that’s it - so simple.
