如何禁用 nix-env 的二进制缓存？

我试图弄清楚 nix-serve / nix 二进制缓存。

在某个时候我补充道：

  nix = {
    binaryCaches = [
      "https://cache.nixos.org/"
      "http://127.0.0.1:8899"
    ];
    binaryCachePublicKeys = [
      "my-nix-cache:z3o8Kf/PTzehVpMsE2KoYyf5rkU/XCR0+AfEvtKSgo8="
    ];
    trustedUsers = [ "root" "chris" ];
  };

127.0.0.1然后我删除了+ ran的条目nixos-rebuild switch。

但是每次我尝试使用nix-env时，它仍然尝试用作127.0.0.1:8899二进制缓存......

我怎样才能删除它/禁用它？

删除~/.config/nix/nix.conf为我解决了这个问题（但我不知道它是如何创建的）。

也许我本可以删除该条目，127.0.0.1:8899但我很懒。

substituters = https://cache.nixos.org https://cache.nixos.org/ https://hydra.iohk.io http://127.0.0.1:8899 ...
