Problem

Using following code:

<style lang="postcss" scoped>
.test {
  color: #000000;
}
</style>

I get this error:

ERROR in ./node_modules/vuepress/lib/default-theme/Layout.vue?vue&type=style&index=2&id=25045c01&lang=postcss&scoped=true (./node_modules/vue-loader/lib??vue-loader-options!./node_modules/vuepress/lib/default-theme/Layout.vue?vue&type=style&index=2&id=25045c01&lang=postcss&scoped=true)
Module parse failed: Unexpected token (172:0)
You may need an appropriate loader to handle this file type.

The above code works just fine when omitting the lang tag. However, that breaks syntax highlighting.

Also see vuejs/vue-cli#1285 and #506

I saw numerous issues for this but I can't seem to find any solution to fix it. This comment implies that it can be fixed, having vue-loader configured doesn't solve the issue?

@r0skar Did you have it fixed in vuepress?
