This version of Nixpkgs requires Nix >= ${requiredVersion}, please upgrade:
- If you are running NixOS, `nixos-rebuild' can be used to upgrade your system.
- Alternatively, with Nix > 2.0 `nix upgrade-nix' can be used to imperatively
upgrade Nix. You may use `nix-env --version' to check which version you have.
- If you installed Nix using the install script (https://nixos.org/nix/install),
it is safe to upgrade by running it again:
curl -L https://nixos.org/nix/install | sh
For more information, please see the NixOS release notes at
https://nixos.org/nixos/manual or locally at
${toString ./nixos/doc/manual/release-notes}.
If you need further help, see https://nixos.org/nixos/support.html
