It was great starting with the nixos, but after sometime stuck on the installation, build and run the code.

I am using mac os, and while installing it the package stuck in the middle. so I follow the simple steps for installation and tha help alot while installation.

• Start with the command line
  • open terminal and run sh <(curl -L https://nixos.org/nix/install) --daemon after successful installation try to run nix command
  • I am hoping it is falling for you also
  • goto your bashrc or zshrc and check the below lines are there or not

# Nix
if [ -e '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh' ]; then
  . '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh'
fi
# End Nix


export PATH="$PATH:/nix/var/nix/profiles/default/bin"

• if not then add the lines and restart your terminal using zsh or bash
• its time to try again: try with nix Hope nix is working fine then we will move to next steps After succesfull installation we need to experimental-features = nix-command flakes line inside /etc/nix/nix.conf.

once it done, we will test the configuration using a hello word print.

• Open your terminal
• run nix run nixpkgs#hello
• make sure you have internet
• it will download the remote file and print hello world !
• cheers !!!

some more commands:

• nix shell 'nixpkgs#hello'
• nix run 'nixpkgs#hello'
• nix build
• nix flake show
• nix flake init
• nix develop
