nix build

Build a Nix expression (downloading from the cache when possible). See also: nix-build for information about traditional Nix builds from expressions, nix3 flake for information about flakes. More information: https://nixos.org/manual/nix/stable/command-ref/new-cli/nix3-build.html.

• Build a package from nixpkgs, symlinking the result to ./result:

nix build nixpkgs#pkg

• Build a package from a flake in the current directory, showing the build logs in the process:

nix build -L .#pkg

• Build the default package from a flake in some directory:

nix build ./path/to/directory

• Build a package without making the result symlink, instead printing the store path to the stdout:

nix build --no-link --print-out-paths
