12 months ago Running as sudo works; echo "Hello Nix" | sudo nix run "nixpkgs#ponysay".
Is that the expected workflow?
Is it expected that root is the owner of ~/.cache/nix?

12 months ago That is unexpected. I'll try to reproduce.
We don't create a ~/.cache directory, the installer runs as root, and won't manipulate your user homedir.

12 months ago I'm unfortunately not able to reproduce this.
Here I check to see I have no existing nix related things in my homedir:
ephemeraladmin@mac-epic-turducken ~ % ls ~/.cache ~/.local/state/nix ~/.nix-profile
ls: /Users/ephemeraladmin/.cache: No such file or directory
ls: /Users/ephemeraladmin/.local/state/nix: No such file or directory
ls: /Users/ephemeraladmin/.nix-profile: No such file or directoryProceeding with install:
ephemeraladmin@mac-epic-turducken ~ % curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install
info: downloading installer https://install.determinate.systems/nix/tag/v0.11.0/nix-installer-aarch64-darwin
`nix-installer` needs to run as `root`, attempting to escalate now via `sudo`...
Nix install plan (v0.11.0)
Planner: macos (with default settings)
Planned actions:
* Create an APFS volume `Nix Store` for Nix on `disk3` and add it to `/etc/fstab` mounting on `/nix`
* Fetch `https://releases.nixos.org/nix/nix-2.17.0/nix-2.17.0-aarch64-darwin.tar.xz` to `/nix/temp-install-dir`
* Create a directory tree in `/nix`
* Move the downloaded Nix into `/nix`
* Create build users (UID 300-332) and group (GID 30000)
* Configure Time Machine exclusions
* Setup the default Nix profile
* Place the Nix configuration in `/etc/nix/nix.conf`
* Configure the shell profiles
* Configure Nix daemon related settings with launchctl
* Remove directory `/nix/temp-install-dir`
Proceed? ([Y]es/[n]o/[e]xplain): y
INFO Step: Create an APFS volume `Nix Store` for Nix on `disk3` and add it to `/etc/fstab` mounting on `/nix`

To get started using Nix, open a new shell or run `. /nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh`
ephemeraladmin@mac-epic-turducken ~ % . /nix/var/nix/profiles/default/etc/profile.d/nix-daemon.shI check again for nix files in my homedir:
ephemeraladmin@mac-epic-turducken ~ % ls ~/.cache ~/.local/state/nix ~/.nix-profile
ls: /Users/ephemeraladmin/.cache: No such file or directory
ls: /Users/ephemeraladmin/.local/state/nix: No such file or directory
ls: /Users/ephemeraladmin/.nix-profile: No such file or directory
ephemeraladmin@mac-epic-turducken ~ % nix --version
nix (Nix) 2.17.0
ephemeraladmin@mac-epic-turducken ~ % echo "Hello Nix" | nix run "nixpkgs#ponysay"

ls: /Users/ephemeraladmin/.local/state/nix: No such file or directory
ls: /Users/ephemeraladmin/.nix-profile: No such file or directory

I suspect your ~/.cache directory may have other contents and been created by something else, which made it root for some reason? "Real" systems are a lot more messy than a stock install. 😅
Maybe you can look in ~/.cache and see what else is in there?

11 months ago Thanks for the reply and all the info. I really appreciate it!! I'll go digging and see what I can find.

11 months ago I just ran into the issue too, running sudo chown -R $(whoami) ~/.cache/nix solved it, so the problem is just that whatever is creating the nix cache folder is creating it as root, and since I got the error on my first ever run of the nix command, the folder was definitely created by the installer
Considering the installer promotes itself to root, and that nothing else has been run between the install and nix fmt . (in my case), it's almost definitely a bug in either the installer itself, or one of its dependencies

7 months ago @BLucky-gh Thank you! I just fresh-installed and ran into this as well and that fixed it for me.
After a clean install I'm unable to run
echo "Hello Nix" | nix run "nixpkgs#ponysay"in step 2 of the quick start guide.Environment info:
Example command execution after an uninstall and reinstall:
If there is additional information you need let me know.
Thanks for the help!
