Build failed on ubuntu with Nix: failed to run custom build command for `style v0.0.1`

[rice7th]

As the title says, style v0.0.1 fails to build.

This is the full error message:

error: failed to run custom build command for `style v0.0.1 (/home/USER/git/servo/components/style)`

Caused by:

  --- stderr

  The style crate requires enabling one of its 'servo' or 'gecko' feature flags and, in the 'servo' case, one of 'servo-layout-2013' or 'servo-layout-2020'.

Huh. How are you building it?

./mach build --release

Same problem without release flag

@jdm the problem persists even here on MacOS without nix!
