由于架构不同，我们在 Mac OS X 上使用 NixOps 时遇到了问题：
x86_64-darwin (vs.) x86_64-linux
我们根据本手册建立了主机设置：
构建主机设置（VirtualBox 客户机）
https:// functional-orbitz.blogspot.de/2013/05/setting-up-nixops-on-mac-os-x-with.html（参见步骤 5.设置分布式构建）
ssh nix-build-server有效，我们在 Mac 上设置了以下环境变量：
NIX_BUILD_HOOK NIX_CURRENT_LOAD NIX_REMOTE_SYSTEMS使用手册中的值。
问题。在 Linux 上，我会使用：strace -f -e execve nixops ...查看调用了哪些程序，或者至少查看调用这些程序时使用了哪些参数。如何找出返回了意外的文件结束错误？
错误。我们看到 nixops 想要使用 buildhost 并输出：
nixops deploy -d test -I nixpkgs=/Users/josh/.nix-defexpr/channels/nixos/ --show-trace
building all machine configurations...
using predefined remote systems file: /Users/josh/sample_clj/remote-systems.conf

答案1
解决方案
暂时不要直接从 Mac 机器上使用 nixops！这看起来很诱人，但我们尝试了几个小时都没有成功！使用https:// functional-orbitz.blogspot.de/2013/05/setting-up-nixops-on-mac-os-x-with.html对我们根本不起作用。事实上，那是巨大的时间浪费。
相反：将 nixos 安装到 VirtualBox 中并从那里进行 nixops 部署！
未来的解决方案
这方面最有前途的项目似乎是 hyperkit 中的 nixos：
但他们还没有到达那里。然后他们将从 x86_64-darwin 机器透明地构建 x86_64-linux 代码。
因此，一旦 hyperkit-builder 更加稳定，我就会切换到该工具链，而不是使用带有 nixos guest 的 VirtualBox。
