使用 stack 与我的系统GHC 8.0.1安装，我收到以下错误：

$ cabal get shuffle
$ cd shuffle
$ stack build --system-ghc --stack-yaml my-stack.yaml shuffle

请注意，上面的错误消息提到了两个版本的Cabal库：

  • Cabal-1.24.0.0（包含在GHC 8.0.1中）

  • Cabal-1.24.2.0（包含在LTS 7.15 Haskell快照中）

my-stack.yaml 文件包含：

$ cat my-stack.yaml 
resolver: lts-7.15

# See http://stackoverflow.com/questions/39564607/error-installing-the-shuffle-library-with-stack.
explicit-setup-deps:
  shuffle: true

# Local packages, usually specified by relative directory name
packages:
- '.'
extra-deps:
- logict-state-0.1.0.2
- pqueue-1.3.2
- uhc-util-0.1.6.7
- uuagc-0.9.52.1
- uuagc-cabal-1.0.6.0
- uulib-0.9.22

我可以通过将 Cabal-1.24.0.0 （来自GHC的版本）添加到上面的 extra-deps 来构建包，但我不明白为什么它是必要的 .
