I just updated my macOS system version from 12.0 to 12.1 (21C52), and it seems like nix and home-manager have been mysteriously “uninstalled”:
❯ which nix-shell nix-shell not found
Thankfully my nix store has been preserved however:
❯ ls /nix/store | head -n 5 00axqwj2bc90ng4mz4vdzifcc4hjzaxb-compat-netbsd-9.2.drv 00ndzg2zv9wjxkjh9v7yv4plsg90fyxj-python3.9-shortuuid-1.0.1.drv 00qr10y7z2fcvrp9b2m46710nkjvj55z-update-autotools-gnu-config-scripts.sh 00sv2racjxv28m0mmr982ik8sbznx2c8-mailcap-2.1.53.drv 01895fqr82pmjqmw7ni7drl7j81m24my-ruby2.7.4-ttfunk-1.7.0.drv
How do I “re-enable” nix now?
