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

b) for `nixos-rebuild` you can add ‘python2.7-Pillow-6.2.2’ to
   `nixpkgs.config.permittedInsecurePackages` in the configuration.nix,
   like so:

     {
       nixpkgs.config.permittedInsecurePackages = [
         "python2.7-Pillow-6.2.2"
       ];
     }

c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
   ‘python2.7-Pillow-6.2.2’ to `permittedInsecurePackages` in
   ~/.config/nixpkgs/config.nix, like so:

     {
       permittedInsecurePackages = [
         "python2.7-Pillow-6.2.2"
       ];
     }
