During compiling one of dependencies cabal outputs:

src/Data/Store/Internal.hs:393:12: error: [GHC-39999]
    • Could not deduce ‘IsSequence (SCV.Vector a)’
        arising from a use of ‘pokeSequence’
      from the context: Store a
        bound by the instance declaration
        at src/Data/Store/Internal.hs:391:10-40
      There are instances for similar types:
        instance Storable a => IsSequence (SV.Vector a)
          -- Defined in ‘Data.Sequences’
        instance UV.Unbox a => IsSequence (UV.Vector a)
          -- Defined in ‘Data.Sequences’
        instance IsSequence (V.Vector a) -- Defined in ‘Data.Sequences’
    • In the expression: pokeSequence
      In an equation for ‘poke’: poke = pokeSequence
      In the instance declaration for ‘Store (SCV.Vector a)’

393 |     poke = pokeSequence

Workaround: downgrade store version by adding store==0.7.17.
