cabal: Could not resolve dependencies:

[__1] trying: base-4.11.1.0/installed-4.1... (dependency of urlpath)
[__2] next goal: attoparsec-uri (dependency of urlpath)
[__2] rejecting: attoparsec-uri-0.0.6 (conflict: urlpath =>
attoparsec-uri==0.0.5.1)

After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: urlpath, base, attoparsec-uri
