Question

我已将following nix表达式添加到我的项目（nixpkgs中的verbatem）并尝试构建它，但是我收到以下错误消息：

these derivations will be built:
  /nix/store/l6l5j1gas74pnzc2pb8w9fv2namxpgki-godot-3.0.6.drv

Try 'cp --help' for more information.
builder for '/nix/store/l6l5j1gas74pnzc2pb8w9fv2namxpgki-godot-3.0.6.drv' failed with exit code 1

可能是什么原因造成的？请注意，当我简单地将godot添加到我的nix配置中（在使用nixos-18.09通道的NixOS中）时，它的安装和运行就很好。这些表达方式不一样吗？如果是这样，为什么它在全球范围内而不是在本地范围内起作用？

注意：：这是nix表达式中调用cp shell命令的部分（与上述错误有关）：

  installPhase = ''
    mkdir -p "$out/bin"
    cp bin/godot.* $out/bin/godot

    mkdir "$dev"
    cp -r modules/gdnative/include $dev

    mkdir -p "$man/share/man/man6"
    cp misc/dist/linux/godot.6 "$man/share/man/man6/"

    mkdir -p "$out"/share/{applications,icons/hicolor/scalable/apps}
    cp misc/dist/linux/godot.desktop "$out/share/applications/"
    cp icon.svg "$out/share/icons/hicolor/scalable/apps/godot.svg"
    cp icon.png "$out/share/icons/godot.png"
    substituteInPlace "$out/share/applications/godot.desktop" \
      --replace "Exec=godot" "Exec=$out/bin/godot"
  '';

Godot Nix表达失败
