Can't install php81Extensions.blackfire

This issue has been tracked since 2022-12-16.

I'm trying to add the blackfire extension to my devbox.json. After looking through NixOS search it seems the correct
package name should be php81Extensions.blackfire for PHP 8.1.

Adding it to my devbox.json:

  "packages": [
  "shell": {
    "init_hook": null
  "nixpkgs": {
    "commit": "52e3e80afff4b16ccb7c52e9f0f5220552f03d04"

results in the following error:

Installing nix packages. This may take a while...
Error: apply Nix derivation: running command /nix/var/nix/profiles/default/bin/nix-env --profile /Users/calvinbaart/dev/devbox_test/.devbox/nix/profile/default --install -f /Users/calvinbaart/dev/devbox_test/.devbox/gen/development.nix: exit status 1 with command output: replacing old 'devbox-development'

             |                             ^
(use '--show-trace' to show detailed location information)

It should be noted that other extensions work perfectly (for example the imagick extension from the other issue)

The generated development.nix is this:

  pkgs = import (fetchTarball {
    url = "";
  }) {
    php81 = pkgs.php81.withExtensions ({ enabled, all }: enabled ++ (with all; [ blackfire ]));
  in with pkgs;
buildEnv {
  ignoreCollisions = true;
  name = "devbox-development";
  paths = [
  pathsToLink = [ "/bin" "/share" "/lib"];

Thanks for the detailed report. Can you try updating the nixpkgs.commit in your devbox.json to 7a3f450e4af7c015a78d5d182499c8c6170418e5?

  "packages": [
  "shell": {
    "init_hook": null
  "nixpkgs": {
    "commit": "52e3e80afff4b16ccb7c52e9f0f5220552f03d04"

I think the problem is that this version of the package doesn't include an extension name by default. A newer version does though - see NixOS/[email protected]152d320.

@mikeland86 do you know if we should be doing something like this?

-php81 = pkgs.php81.withExtensions ({ enabled, all }: enabled ++ (with all; [ blackfire ]));
+php81 = pkgs.php81.withExtensions ({ enabled, all }: enabled ++ (with all; [ (blackfire // { extensionName = "blackfire"; }) ]));

I'm not sure if this is a devbox problem or if this was just an issue with the package.

7a3f450e4af7c015a78d5d182499c8c6170418e5 works perfectly. I did get an error about the license being unfree but that is unrelated to this ticket.

The extension registers correctly with the new commit:
