Description
Some packages have collisions, which makes users unable to get a devshell.
I am not sure if the collision is an issue of those packages. But I think it would be good if dream2nix could ignore them.
I can create a PR to add ignoreCollisions = true; to pyEnv, but I am not sure if it should be gated behind an option.
cc @phaer: author of #951 which removes ignoreCollisions.
To reproduce this issue, run nix build .#default.devShell in a flake with the following files and you will get this error:
error: builder for '/nix/store/q4nyhwnpm2fbxs2rxpazmh0x2njgzphq-python3-3.10.15-env.drv' failed with exit code 25;
