Я пытался установить ghc-mod локально в проекте Stack.
Однако всякий раз, когда я пытаюсь stack build ghc-mod, я получаю сбой плана сборки, подобный следующему:
Error: While constructing the build plan, the following exceptions were encountered:

needed since ghc-mod is a build target.
Если я последую совету предупреждения о добавлении недостающих зависимостей в мой ключ stack.yaml extra-deps, я просто получу больше рекурсивных ошибок и, в конечном итоге, план сборки, в котором есть конфликт сборки где-то, что для меня по крайней мере не очевидно, и нет полезные подсказки, чтобы решить это.

resolver: ghc-8.0.2
Я что-то здесь упускаю? Конечно, это должно быть проще. Я считаю, что ghc-mod не поддерживается после GHC 8.2, поэтому я намеренно настроил проект с GHC 8.0.2, что подтверждается запуском GHCI (не без собственного длинного списка предупреждений).
Я также пытался использовать версию 7.x GHC, и у нее были те же проблемы, но с немного другими зависимостями.
