[1 of 4] Compiling Control.Monad.Imperative.Internals ( Control/Monad/Imperative/Internals.hs, dist/build/Control/Monad/Imperative/Internals.o )

Control/Monad/Imperative/Internals.hs:54:27: error:
    • No instance for (Applicative (MIO r))
        arising from the 'deriving' clause of a data type declaration
      Possible fix:
        use a standalone 'deriving instance' declaration,
          so you can specify the instance context yourself
    • When deriving the instance for (Monad (MIO r))
