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 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}. |
