I currently have this devbox.json:
{
"packages": [
"php",
"php81Extensions.blackfire",
"php81Packages.composer"
],
"shell": {
"init_hook": null
},
"nixpkgs": {
"commit": "7a3f450e4af7c015a78d5d182499c8c6170418e5"
}
}And when executing devbox shell I get this error:
Error: apply Nix derivation: running command /nix/var/nix/profiles/default/bin/nix-env --profile /Users/calvinbaart/dev/test_php/.devbox/nix/profile/default --install -f /Users/calvinbaart/dev/test_php/.devbox/gen/development.nix: exit status 1 with command output: replacing old 'devbox-development'

error: Package ‘php-blackfire-1.84.0’ in /nix/store/wfcarnr78spyfyjyypb946j2ss1awp9l-source/pkgs/development/tools/misc/blackfire/php-probe.nix:200 has an unfree license (‘unfree’), refusing to evaluate.
a) To temporarily allow unfree packages, you can use an environment variable
for a single invocation of the nix tools.
$ export NIXPKGS_ALLOW_UNFREE=1
Note: For `nix shell`, `nix build`, `nix develop` or any other Nix 2.4+
(Flake) command, `--impure` must be passed in order to read this
environment variable.
b) For `nixos-rebuild` you can set
{ nixpkgs.config.allowUnfree = true; }
in configuration.nix to override this.
Alternatively you can configure a predicate to allow specific packages:
{ nixpkgs.config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [
"php-blackfire"
];
}
c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
{ allowUnfree = true; }
to ~/.config/nixpkgs/config.nix.
(use '--show-trace' to show detailed location information)
In the error they recommend setting allowUnfree or nixpkgs.config.allowUnfree. So I tried that:
{
"packages": [
"php",
"php81Extensions.blackfire",
"php81Packages.composer"
],
"shell": {
"init_hook": null
},
"allowUnfree": true,
"nixpkgs": {
"commit": "7a3f450e4af7c015a78d5d182499c8c6170418e5",
"allowUnfree": true,
"config": {
"allowUnfree": true
}
}
}But that doesn't work. I also tried setting the environment variable in the init_hook but it's too late at that point. The only way to actually run it for now is NIXPKGS_ALLOW_UNFREE=1 devbox shell which I don't really like or creating a ~/.config/nixpkgs/config.nix file which would be another setup step.
@calvinbaart thank you for opening this issue! We've been considering having allowUnfree set to true by default, but I think your suggestion for the config is interesting too. Will discuss with the team for our sprint next week.
Another possibility would be just passing through all the config options to nixpkgs.config. For example:
{
"packages": [
"php",
"php81Extensions.blackfire",
"php81Packages.composer"
],
"shell": {
"init_hook": null
},
"nixpkgs": {
"commit": "7a3f450e4af7c015a78d5d182499c8c6170418e5",
"config": {
"allowUnfree": true,
"allowUnfreePredicate": [ "php.blackfire" ],
"otherOptions" ...
}
}
}This would make it a bit more flexible for other possible config options, but I think that would be a bit more complicated
then just passing through allowUnfree only.
Creating a new issue to cover the nix config issues, and closing this since allowUnfree will be set to false in the upcoming 0.2.1 release. @calvinbaart we can continue discussion on the interface at #462 for upcoming releases
