Answer 1

1. Open /etc/zshrc and look for the following lines (probably at the end of the file):

    # 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
   

2. Copy these lines and delete them from this file.

3. Open ~/.zshrc and add the above copied lines to the end of this file

4. Reboot terminal and nix should work now.
