[1 of 8] Compiling Data.Conduit.Internal.Pipe ( Data/Conduit/Internal/Pipe.hs, dist/build/Data/Conduit/Internal/Pipe.o )

Data/Conduit/Internal/Pipe.hs:575:13: error:
    • Could not deduce (Monad m) arising from a use of ‘transPipe’
      from the context: Functor m
        bound by the type signature for:
                   hoist :: Functor m =>
                            (forall a. m a -> n a) -> Pipe l i o u m b -> Pipe l i o u n b
        at Data/Conduit/Internal/Pipe.hs:575:5-9
      Possible fix:
        add (Monad m) to the context of
          the type signature for:
            hoist :: Functor m =>
                     (forall a. m a -> n a) -> Pipe l i o u m b -> Pipe l i o u n b
    • In the expression: transPipe
      In an equation for ‘hoist’: hoist = transPipe
      In the instance declaration for ‘MFunctor (Pipe l i o u)’
