The devenv init likely overwrote the default devenv configuration of the IHP project. Can you try without devenv init?

no luck

~/work on ☁️  (us-west-2)
❯ rm -rf blog

~/work on ☁️  (us-west-2)
❯ ihp-new blog

We will now create your new IHP project. This may take up to 30 seconds.

🚀 Project created, happy coding :)
You can start the server by running:
  cd blog
  devenv up

Can you try the following?

cd blog
nix develop --impure
devenv up

If that works: direnv might not be correctly working in your setup

thanks for your help! No luck yet

Try this:

 nix --extra-experimental-features nix-command develop --impure

(Sorry for nix being terrible here, I have reported that error message to the nix people in the past here NixOS/nix#7000 )

almost there!

I added this line to nix.conf and got it working!

  # ~/.config/nix/nix.conf
  substituters = https://cache.nixos.org https://devenv.cachix.org https://digitallyinduced.cachix.org
  trusted-public-keys = cache.nixos.org-:XXX
+ experimental-features = flakes nix-command

(devenv) $ devenv up

geofflangenderfer commented

one idea: append this line to the user's nix.conf if it's not already present:

if ! grep -q "experimental-features" ~/.config/nix/nix.conf
then
    echo "experimental-features = flakes nix-command" >> ~/.config/nix/nix.conf
fi

I'm not sure if you would add this to .envrc or somewhere else.

IHP should be able to run without these flags present. The nix-direnv plugin we use for direnv explicitly passes --extra-experimental-features nix-command flakes to nix. So something is still not working as expected here.
