Trying to start an IHP application but devenv and direnv are giving me errors

Question

I just installed IHP into my Windows Subsystem for Linux and I have been trying to run the "devenv up" command, but it gives me multiple errors.

I will try to find any information about my system and laptop needed to answer this question.

When I cd to the application directory, direnv gives me the following message:

direnv: PS1 cannot be exported. For more information see https://github.com/direnv/direnv/wiki/PS1

I don't know if there is an issue in my system or the framework setup itself.

If I try to run the devenv up command anyway, the next error appears:

error: experimental Nix feature 'nix-command' is disabled; add '--extra-experimental-features nix-command' to enable it

I tried to run the command with direnv uninstalled, but then devenv doesn't find any defined processes.

I am trying to follow the IHP guide to develop the application in this page of the ducomentation: https://ihp.digitallyinduced.com/Guide/your-first-project.html#starting-your-app

Answer 1

The PS1 issue you link to should cover that issue. If you run direnv allow from your project directory you should be able to ignore that warning.

You can enable flakes by modifying your nix config. Try adding:

experimental-features = nix-command flakes

to e.g. ~/.config/nix/nix.conf.

Then you should be able to start the dev server from your project directory:

nix develop --impure
devenv up
