       a) To temporarily allow broken packages, you can use an environment variable

          for a single invocation of the nix tools.

            $ export NIXPKGS_ALLOW_BROKEN=1

          Note: When using `nix shell`, `nix build`, `nix develop`, etc with a flake,

                then pass `--impure` in order to allow use of environment variables.

       b) For `nixos-rebuild` you can set

         { nixpkgs.config.allowBroken = true; }

       in configuration.nix to override this.

       c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add

         { allowBroken = true; }

       to ~/.config/nixpkgs/config.nix.

       error: Package ‘python-2.7.18.8’ in /nix/store/5zv0v05ycsc5r38j6w0rw31idkvi0g2s-source/pkgs/development/interpreters/python/cpython/2.7/default.nix:398 is marked as insecure, refusing to evaluate.

       Known issues:

        - Python 2.7 has reached its end of life after 2020-01-01. See https://www.python.org/doc/sunset-python-2/.

       You can install it anyway by allowing this package, using the

       following methods:

       a) To temporarily allow all insecure packages, you can use an environment

          variable for a single invocation of the nix tools:

            $ export NIXPKGS_ALLOW_INSECURE=1

          Note: When using `nix shell`, `nix build`, `nix develop`, etc with a flake,

                then pass `--impure` in order to allow use of environment variables.

       b) for `nixos-rebuild` you can add ‘python-2.7.18.8’ to

          `nixpkgs.config.permittedInsecurePackages` in the configuration.nix,

          like so:

            {

              nixpkgs.config.permittedInsecurePackages = [

                "python-2.7.18.8"

              ];

            }

       c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add

          ‘python-2.7.18.8’ to `permittedInsecurePackages` in

          ~/.config/nixpkgs/config.nix, like so:

            {

              permittedInsecurePackages = [

                "python-2.7.18.8"

              ];

            }
