When sandbox builds are enabled,

Nix will setup an isolated environment for each build process.

It is used to remove further hidden dependencies set by the build environment to improve reproducibility.

This includes access to the network during the build outside of <code>fetch*</code> functions and files outside the Nix store.

Depending on the operating system access to other resources are blocked as well (ex. inter process communication is isolated on Linux);

Line 14:

Sandboxes are not enabled by default in Nix as there are cases where it makes building packages harder (for example <code>npm install</code> will not work due missing network access).

In pull requests for [https://github.com/NixOS/nixpkgs/ nixpkgs] people are asked to test builds with sandboxing enabled (see <code>Tested using sandboxing</code> in the pull request template) because in [https://nixos.org/hydra/ official hydra builds] sandboxing is also used.

Depending if you use NixOS or other platforms you can use one of the following methods to enable sandboxing.
