This version of Nixpkgs requires Nix >= ${requiredVersion}, please upgrade:
|
|
|
|
|
|
2018-06-25 00:35:06 +02:00
|
|
|
- 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
|
