Troubleshooting

Your system can't find Nix

You've run the installer but when you run any Nix command, like nix --version, and Nix isn't found:

$ nix --version
bash: nix: command not found

Nix isn't currently on your PATH.

Initialize your Nix profile:
```
. /nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh
```
This script sets up various environment variables that Nix needs to work. The installer does prompt you to run this command when it's finished with installation but it's easy to miss or forget.
Ensure that you're not overriding your existing PATH somewhere. If you have a bash_profile, zshrc, or other file that modifies your PATH, make sure that it appends to your PATH rather than setting it directly.
```
# Do this ✅
PATH=$PATH${PATH:+:}path1:path2:path3

# Not this ❌
PATH=path1:path2:path3
```
