Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: talash-0.1.0.0 (user goal)
[__1] next goal: ghc-compact (dependency of talash)
[__1] rejecting: ghc-compact-0.1.0.0/installed-0.1.0.0 (conflict: talash =>

[__2] skipping: base-4.15.0.0, base-4.14.1.0, base-4.14.0.0 (has the same
characteristics that caused the previous version to fail: excluded by
constraint '>=4.9.0 && <4.14' from 'ghc-compact')

[__2] fail (backjumping, conflict set: base, ghc-compact, talash)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: base, talash, ghc-compact
