我正在尝试使用 nix 来构建 dotnet (sdk 5) 项目。

配置类似于

stdenv.mkDerivation {
# builder = "${bash}/bin/bash";
# args = [ ./builder.sh ];
name = "mypackage";
src = ./.;
HOME = "/tmp/test-home";
DOTNET_CLI_TELEMETRY_OPTOUT = 1;
nativeBuildInputs = [ nodejs ];
buildInputs = [ dotnet openssl cacert  ];
configurePhase = ''
  export HOME=$PWD/home
  runHook preConfigure
  dotnet nuget list source
  dotnet nuget locals all --list
  dotnet restore
  runHook postConfigure
'';
buildPhase = ''
  export DOTNET_CLI_TELEMETRY_OPTOUT=1
  export DOTNET_NOLOGO=1
  ${dotnet}/bin/dotnet publish ProjectDirectory --self-contained -r linux-x64 -c Release
'';
installPhase = ''
  mkdir -p $out/
'';

};

for 参数中的HOME属性stdenv.mkDerivation仅适用于 nix-shell。由于 nix-shell 将继承 normal $HOME，我需要设置$HOME到另一个空目录来模仿构建阶段的行为。

  • 手动使用nix-shell和运行时，它工作正常。dotnet restore

  • 使用时nix-build，构建失败，运行时出现以下错误dotnet restore

手动设置nix-build和nix-shell --pure何时设置有什么区别？HOME

通过从 github NixOS/nixpkgs 存储库读取代码，似乎有几个 dotnet 包正在nuget手动使用并dotnet restore与本地源一起使用。那有必要吗？

我对 api.nuget.org 进行了更多测试。

运行curl https://api.nuget.org/v3/index.json -v，我得到：

  • 直接在 nixos 终端下运行时工作正常
  • 工作正常nix-shell --pure
  • 中的错误nix-build，curl: (6) Could not resolve host: api.nuget.org
