Nix
Requirements
- Install Nix
- Enable Flakes permanently
For macOS users
Add the following lines to configuration file located at /etc/nix/nix.conf:
trusted-public-keys = hydra.iohk.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ= cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY=
substituters = https://cache.iog.io https://cache.nixos.org
Restart the nix-daemon service:
sudo launchctl stop org.nixos.nix-daemon
sudo launchctl start org.nixos.nix-daemon
If the following messages appear running the scripts detailed in the section below, it means that Nix is not picking up the substituters we described earlier and is unable to use them as a derivation cache:
warning: ignoring untrusted substituter 'https://cache.iog.io'
in which case it is recommended to go over the steps detailed in this section again, or look for alternative ways to add extra substituters in nix.conf.
Enabling the development environment
To enable the development environment exposed by the project's Nix flake, you can start a development shell by running the following command from within the project's root:
nix develop
Alternatively, if you are using nix-direnv (recommended), you can run:
direnv allow
that will enable the development shell according to the contents of .envrc. It is advisable not to run direnv allow blindly and always check the contents of .envrc files first to ensure nothing malicious is executed.
