Структурированный режим Haskell не удается установить

/ 21 сентября 2018

Я пытаюсь обновить мой структурированный режим haskell с помощью команды установки cabal.К сожалению, он не работает 

obelix:~ rk$ cabal install structured-haskell-mode
Warning: The install command is a part of the legacy v1 style of cabal usage.

Please switch to using either the new project style and the new-install
command or the legacy v1-install alias as new-style projects will become the
default in the next version of cabal-install. Please file a bug if you cannot
replicate a working v1- use case with the new-style commands.

For more information, see: https://wiki.haskell.org/Cabal/NewBuild

Кажется, он вызывает конструктор Deriving с неправильным количеством аргументов.Любые предложения для быстрого исправления?
