Hi,
I am trying to setup vim with python3 support (needed for plugins).
The answer suggested in https://discourse.nixos.org/t/solved-help-getting-vim-with-python3-support-working/ does not work - it doesn’t allow me to rebuild the system. If I do what they suggest, I get an error:
error:

Did you mean python3?
What fixes this error is changing python = ... to python3 = ...
My vim.nix file looks like:
{ pkgs, ... }:
let
myVim = pkgs.vim_configurable.override {
python3 = pkgs.python3;
};
in
{
programs.vim.defaultEditor = true;
environment.systemPackages = with pkgs; [
(myVim.customize {
name = "vim-with-python3";
vimrcConfig.packages.myplugins = with pkgs.vimPlugins; {
start = [ vim-nix ]; # load plugins on startup
};
vimrcConfig.customRC = ''
" custom vimrc settings
'';
})
];
}
This, however, still doesn’t compile with python3 support (:echo has('python3') returns 0)
Does anybody know how to fix this?
Thanks!
