# cabal v2-build Resolving dependencies... cabal: Could not resolve dependencies: [__0] trying: p-1.0 (user goal) [__1] next goal: q (user goal) [__1] rejecting: q-1.0 (requires library from p, but the component is not buildable in the current environment) [__1] fail (backjumping, conflict set: p, q) After searching the rest of the dependency tree exhaustively, these were the goals I've had most trouble fulfilling: p (2), q (2)
