post-css error using yarn

[sinedied]

When yarn is used as a package manager, building project result in a post-css error:

TypeError: Class extends value undefined is not a constructor or null

I'm not sure what can be done about it, as removing node_modules folder and running npm install instead solves the issue.
Ideas welcome.
