使用 stack 安装 shuffle 库时出错

Question

使用 stack 1.2.0 和 LTS 7.0 安装 shuffle 库时出现以下错误：

$ cabal get shuffle
$ cd shuffle-0.1.3.3
$ stack build
...
/tmp/shuffle-0.1.3.3/Setup.hs:2:1: error:
    Failed to load interface for ‘Distribution.Simple.UUAGC’
    Perhaps you meant
      Distribution.Simple.UHC (from Cabal-1.24.0.0)
      Distribution.Simple.GHC (from Cabal-1.24.0.0)
      Distribution.Simple.JHC (from Cabal-1.24.0.0)
    Use -v to see a list of the files searched for.

/tmp/shuffle-0.1.3.3/Setup.hs:3:1: error:
    Failed to load interface for ‘UU.UUAGC’
    Use -v to see a list of the files searched for.

    Process exited with code: ExitFailure 1

我正在使用以下 stack.yaml 文件：

resolver: lts-7.0

# Local packages, usually specified by relative directory name
packages:
- '.'
extra-deps:
- logict-state-0.1.0.2
- pqueue-1.3.1.1
- uhc-util-0.1.6.6
- uuagc-0.9.52.1
- uuagc-cabal-1.0.6.0
- uulib-0.9.22

我需要 add/change 图书馆或 stack.yaml 的东西吗？（我使用 cabal-install 没有问题）。

Answer 1

看来此软件包需要您安装 uuagc-cabal 才能构建它。从 Cabal-1.23 开始，这些 Setup.hs 文件的依赖包可以在 cabal 文件的 custom-setup 部分中捕获。

关于堆栈的此功能的票证似乎与此处相互关联：

Setup.hs cannot use local snapshot dependencies WAS stack failing to resolve local dependencies of multiple package project #897

Answer 2

我可以通过将以下内容添加到 stack.yaml 来让它工作：

explicit-setup-deps:
    shuffle: true

有关详细信息，请参阅：https://docs.haskellstack.org/en/stable/yaml_configuration/#explicit-setup-deps
