在NixOS中构建Haskell示例时，“ghc:没有这样的文件或目录”错误

Question

A) I试图在NixOS (通道/nixos-18.03)上创建一个带有Stack，ii的项目i)。在遵循用户指南中的HelloWorld实例的同时，为了构建项目，我得到了错误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)迭代，我构建了我的/etc/nixos/configuration.nix文件，如下所示。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) --我还遵循了Stack的Nix集成部分中的步骤。但没有结果。

什么软件包安装ghc-cabal？stack和haskellPackages.cabal-install之间是否有错配？我遗漏了什么？

编辑

我做了一些调查，发现了一些有用的资源。特别是，这篇文章指出，我的问题可能是由一个未解决的动态库引起的。

实际上，在查询加载的库以获取二进制文件时，我得到了下面的结果。

我尝试通过将haskellPackages.stdio和haskellPackages.stdf添加到configuration.nix中来解决缺少的库。但更多的上游错误源自于此(例如:我不能将伊索作为environment.systemPackages依赖项添加)。所以我还没有找到合适的组合。

Answer 1

因此，我在基里尔·扎博斯基的帮助下在一个commercialhaskell/stack 线程中解决了这个问题。错误的原因(在stack new和stack build中)是一个旧的堆栈版本。具体来说，我的本地用户有一个比根(1.9.3)更旧的堆栈(1.9.3)。

版本1.6.5使用Cabal-2.0，从那时起，Cabal (ex base-noprelude)引入了新的特性--使用领先逗号，是在2.2版的哈斯克尔/阴谋集团#4953中实现的。因此Stack无法使用新的格式特性解析阴谋文件。

详细信息见“commercialhaskell/stack Details 线程”。升级本地用户堆栈(nix-env --upgrade stack)解决了这个问题。

ghc -阴谋是ghc构建中的一个工件，包含在ghc二进制发行版中：
