我在 NixOS 上，试图将以下推导添加到nixpkgs：

{ stdenv, lib, openjdk,typedbHome ? "~/.typedb_home", fetchzip}:

let 
  typedbVersion = "2.1.1";
  typedbDirLinux = "typedb-all-linux-${typedbVersion}";
  typedbDirMac = "typedb-all-mac-${typedbVersion}";
  typedbDirWindows = "typedb-all-windows-${typedbVersion}";
  typedbDir = if stdenv.hostPlatform.isWindows then typedbDirWindows
              else if stdenv.isDarwin          then typedbDirMac
                                               else typedbDirLinux;
  linuxSrc = builtins.fetchTarball {
    url = "https://github.com/vaticle/typedb/releases/download/2.1.1/typedb-all-linux-2.1.1.tar.gz";
    sha256 = "15nwm2dr68p67c2xcqigs66gd679j1zr72gqv7qxgvflwyvyz8fb";
  };

  };
  macSrc = fetchzip {

    sha256 = "16hlfy6kh2rnvcralz206q13mghb0rv8wazpg6q3h324p5rdys54";
  };
  srcFolder = if stdenv.hostPlatform.isWindows then windowsSrc
              else if stdenv.isDarwin          then macSrc
                                               else linuxSrc ;
  javaPatch = ''

  version = typedbVersion;

  src = srcFolder;
    
  phases = [ "installPhase" ];

  buildDepends = [ openjdk ];

  installPhase = ''
    echo "here"     # added for debugging
    ls -lah         # "
    echo "--"       # "
    #patch before install
    echo "${javaPatch}" > typedb_java.patch
    patch ./${typedbDir}/typedb typedb_java.patch

    mkdir $out
    cp -r ./${typedbDir} $out
    # add a wrapper script to $out that will move typedb to $typedb
    # this is necessary because typedb needs a writable environment
    echo "
      # on the first start copy everything to typedbHome
      if [ ! -f ${typedbHome}/typedb ]; then 
        mkdir -p ${typedbHome}; 
        cp -r $out/${typedbDir}/* ${typedbHome}; 
    
        # correct permissions so that typedb and the user can write there 
        chmod -R u+rw ${typedbHome}
        chmod u+x ${typedbHome}/typedb
      fi;

我成功地在沙盒模式下构建并安装了它，同时对其进行了几次测试。然后如贡献指南中所述，我检查了所有依赖于更改的包仍然可以使用nix-shell -p nixpkgs-review --run "nixpkgs-review wip"（即使它是一个新包；我刚刚浏览了贡献指南列表）。这也很好。

但是，现在，当我尝试在沙盒模式下重建它时，构建失败并显示以下消息：

build --option build-use-sandbox true -A typedb
these derivations will be built:

似乎我需要的 zip 文件src根本没有下载；这种行为的原因是什么，我该如何解决？

该构建之前工作过，所以我认为它可能与奇怪的缓存行为或类似的东西有关（但是使用沙盒模式应该正常规避）？

完整的回购可以在这里找到。我添加的包在pkgs/server/typedb

我试过了

  • 使用和不使用沙盒模式进行构建，
  • nix-prefetch-url- 在构建之前使用适当的 tarball，
  • 将 repo 重新克隆到不同的位置并使用沙盒模式从头开始构建它
  • 确定是否有非垃圾收集的损坏的预加载 tarball（但是我没有找到任何（可能我寻找它们的方式不太正确））

这个问题也发布在reddit上，但我认为在这里可能更容易找到。
