Cabal repl is unable to resolve dependencies

[ChristopherKing42]

When I try to run it in cabal repl, it is unable to resolve depencies:

Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: fake-package-0 (user goal)
[__1] next goal: sdl2-mixer (dependency of fake-package)
[__1] rejecting: sdl2-mixer-1.1.0, sdl2-mixer-0.1 (conflict: pkg-config
package SDL2_mixer==2.0.0 || >2.0.0, not found in the pkg-config database)
[__1] fail (backjumping, conflict set: fake-package, sdl2-mixer)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: sdl2-mixer, fake-package```
