How do I bypass the binary cache by cachix entirely and build everything on my local machine?

[nalzok]

Hi there, this is a followup question to this thread. The relationship between devenv and cachix is unclear to me, as environment creation and binary caching seems like orthogonal tasks. Do we have to rely on a cachix binary cachix to use devenv?

PS: in that thread I also mentioned that cachix.enable = false; does not silence the warning, contrary to what I have been told. You may want to take another look.

Jumping in to give my "me too". I have cachix.enable = false; and still getting "yelled at"

Thanks, fixed by #1660.

Do we have to rely on a cachix binary cachix to use devenv?

We use a fork of nixpkgs by default which comes with patches for certain integrations. We configure Nix to pull from devenv.cachix.org to serve pre-built binaries for any packages that had to be patched.

Languages that allow configuring a specific version will often have their own caches. The cachix integration can set these up automatically.

To disable the Cachix integration and stop devenv from setting up any caches for you (once #1660 lands):

cachix.enable = false;

To disable all substituters (don't do this):

devenv shell --nix-option substitute false

That's great. Thank you! Could you be a little more specific about the "integrations" though? Like, what do they do, why are they necessary, and can I get these integration if I disable the binary cache and build everything on my local machine?

[sandydoo]

Any service or language that we provide. Disabling caching means that you may end up building more than you'd like locally.

Thanks for the answer. That's helpful!
