cabal: Could not resolve dependencies:

citeproc-hs-0.3.2, citeproc-hs-0.3.1, citeproc-hs-0.3.0 (has the same
characteristics that caused the previous version to fail: excludes
'pandoc-types' version 1.22)
[__6] rejecting: citeproc-hs-0.2 (conflict: citeproc-hs-pandoc-filter =>
citeproc-hs>=0.3.10)
[__6] skipping: citeproc-hs-0.1 (has the same characteristics that caused the
previous version to fail: excluded by constraint '>=0.3.10' from
'citeproc-hs-pandoc-filter')
[__6] fail (backjumping, conflict set: citeproc-hs, citeproc-hs-pandoc-filter,
pandoc-types)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: pandoc, citeproc-hs-pandoc-filter,
pandoc-types, citeproc-hs, binary, base, attoparsec, yaml
Try running with --minimize-conflict-set to improve the error message.
