I’m trying to go through the python nixpkgs manual line by line, and work the examples out to see if I can get something to work. When I paste the line
nix-shell -p 'python35.withPackages(ps: with ps; [ numpy toolz ])'
it works and starts off to work. When I change the python35 to python36 it fails:
nix-shell -p 'python36.withPackages(ps: with ps; [ numpy toolz ])'
error: attribute 'withPackages' missing, at (string):1:94
(use '--show-trace' to show detailed location information)
What’s the new standard if .withPackages is being removed?
