Question

A）我正在尝试在NixOS（channels / nixos-18.03）上使用Stack，ii）创建一个Haskell项目。遵循用户指南中的HelloWorld example来构建项目时，出现错误ghc-cabal: No such file or directory。

$ stack new helloworld new-template
$ cd helloworld
$ sudo stack build
...
Running /run/current-system/sw/bin/make install in directory /root/.stack/programs/x86_64-linux/ghc-8.6.4.temp/ghc-8.6.4/ exited with ExitFailure 2
...
utils/ghc-cabal/dist-install/build/tmp/ghc-cabal-bindist: line 3: /root/.stack/programs/x86_64-linux/ghc-8.6.4.temp/ghc-8.6.4/utils/ghc-cabal/dist-install/build/tmp/ghc-cabal: No such file or directory
make[1]: *** [ghc.mk:990: install_packages] Error 127
make: *** [Makefile:51: install] Error 2

Error: Error encountered while installing GHC with
         make install
         run in /root/.stack/programs/x86_64-linux/ghc-8.6.4.temp/ghc-8.6.4/

       The following directories may now contain files, but won't be used by stack:
         - /root/.stack/programs/x86_64-linux/ghc-8.6.4.temp/
         - /root/.stack/programs/x86_64-linux/ghc-8.6.4/

B），我已经迭代建立了/etc/nixos/configuration.nix文件，如下所示。并且在结果系统中，实际上没有ghc-cabal二进制文件。有cabal，但没有ghc-cabal。

  environment.systemPackages = with pkgs; [
    wget vim emacs
    pkgs.firefoxWrapper pkgs.chromium

    stack
    haskellPackages.ghc
    haskellPackages.cabal-install
    haskellPackages.cabal2nix
    haskellPackages.hdevtools

    tree gnumake which binutils gcc clang coreutils gnutar
    tmux silver-searcher gitAndTools.gitFull
  ];

C），我还按照Stack的Nix Integration部分中的步骤进行操作。但无济于事。

什么软件包安装了ghc-cabal？ stack和haskellPackages.cabal-install之间是否不匹配？我想念什么？

编辑

我做了一些挖掘，发现了一些有用的资源。尤其是this article指出我的问题可能是由于无法解决的动态库引起的。

实际上是在查询加载的库中的二进制文件时，得到以下结果。

我尝试通过将haskellPackages.stdio和haskellPackages.stdf添加到configuration.nix来解决丢失的库。但是由此产生了更多上游错误（例如：我不能将aeson添加为environment.systemPackages依赖项）。所以我还没有找到合适的组合。

ghc-cabal is an artifact in ghc's build, included in ghc binary distributions:

$ ls -l  ~/.stack/programs/x86_64-linux/ghc-tinfo6-8.6.3.tar.xz
-rw-rw-r--. 1 user group 182356948 Dec 25 15:11 ghc-tinfo6-8.6.3.tar.xz
$ tar tvf ~/.stack/programs/x86_64-linux/ghc-tinfo6-8.6.3.tar.xz | grep tmp/ghc-cabal
-rwxr-xr-x ghc/ghc      225936 2018-12-08 00:03 ghc-8.6.3/utils/ghc-cabal/dist-install/build/tmp/ghc-cabal

因此，我在commercialhaskell/stack问题Kirill Zaborsky中借助thread解决了这个问题。错误的原因（在stack new和stack build中）是旧的Stack版本。具体来说，我的本地用户的堆栈（1.6.5）比根（1.9.3）还旧。

版本1.6.5使用Cabal-2.0，此后Cabal（例如base-noprelude）引入了新功能，使用了领先的逗号，该逗号在haskell/cabal#4953中随版本2.2一起实现。。因此，Stack无法使用新的格式功能解析阴谋文件。

有关详细信息，请参见commercialhaskell/stack问题thread。升级本地用户的堆栈（nix-env --upgrade stack）可以解决此问题。

在NixOS中构建Haskell Stack示例时出现“ ghc-cabal：无此文件或目录”错误
