I want to install python with some packages globally, and then I find python3.withPackages and buildEnv.
But I find that nix-env cannot update the packages in it automatically because it only compares python3’s version. And I find a option with upgrade named
-leq which can do what I want to.
Now, If I declarate it in environment.systemPackages, how to let nixos-rebuild to update packages in it?
And how to let nixos-rebuild to update packages defining in bundlerEnv(ruby) automatically?
And how to let nixos-rebuild to update packages defining in buildEnv automatically?
