peti · 2018-03-16T11:58:36Z

Did you source the newly installed shell profile script before entering the nix-enx command to make sure that you shell's environment is set up properly?

And if you, then what is the shell environment in which you run the nix-env command exactly?

teuffy · 2018-03-16T12:23:05Z

Sourcing do you mean source bashrc or ~/.bash_profile ? I did it, restarted the terminal and even the machine
shell environnement - using bash with user profile . I followed the install instruction for bashrc and zshrc. I haven't touch the $NIX_PATH

peti · 2018-03-17T10:37:43Z

I believe that the system-wide profile is going to source the Nix-specific one automatically once it's installed, i.e. there should be an entry for Nix in /etc/profile.d, if I'm not mistaken.

In any case, what is the shell environment in which you run the nix-env command exactly? The output of env would be helpful.

LnL7 · 2018-03-17T11:37:33Z

I think the daemon isn't running for some reason, what's the output of this command?

sudo launchctl list | grep org.nixos

teuffy · 2018-03-17T19:20:54Z

sudo launchctl list | grep org.nixos

119 0 org.nixos.nix-daemon

jeffreyrosenbluth · 2018-03-22T18:22:46Z

I'm having the exact same issue. Running High Sierra 10.13.3 (17D102)

LnL7 · 2018-03-22T18:45:36Z

@teuffy Strange, that indicates the daemon is running. Does restarting it help?

sudo launchctl kickstart -k system/org.nixos.nix-daemon

Tehnix · 2018-03-22T23:44:50Z

Getting the same error and tried running sudo launchctl kickstart -k system/org.nixos.nix-daemon, but no success :(

EDIT: A full reboot seems to have done the trick though!

jeffreyrosenbluth · 2018-03-23T13:28:16Z

Ah, a full reboot worked for me as well.

LnL7 · 2018-03-24T18:44:31Z

That's odd, is 05cb8e5 not in 2.0?

robsimmons · 2018-03-27T02:59:06Z

Same here, log-out and log-in to my account did not work, had to reboot the laptop. (macOS 10.12.6)

shlevy · 2018-03-27T04:27:42Z

I think the plist hard-codes the path to the daemon, so you need to launchctl unload then launchctl load it again

gbersac · 2018-04-10T10:06:32Z

Same issue for me :

$ nix-shell -p nix-info --run "nix-info -m"
error: cannot connect to daemon at '/nix/var/nix/daemon-socket/socket': No such file or directory

waylandc · 2018-08-22T02:12:18Z

@Tehnix

confirmed that a full reboot fixes problem on High Sierra 10.13.4 and nix 2.0.4

nekoniaow · 2019-08-30T01:40:40Z

I confirm that I experienced this issue as well and that rebooting is indeed an effective workaround.
This is for macOS Mojave 10.14.6 and nix 2.2.2.

hlolli · 2019-10-16T16:26:40Z

Experiencing this now on Catalina, I am attempting to reinstall /nix, which succeeded after creating /nix.

I didn't get this error (but some SSL error) when trying to install nix-darwin, but after the restart this started to appear

$ nix-shell -p nix-info --run "nix-info -m"
error: cannot connect to daemon at '/nix/var/nix/daemon-socket/socket': Connection refused

the output of launchctl

$ sudo launchctl list | grep org.nixos
Password:
-	126	org.nixos.activate-system

ADDED:
nevermind, all I had to do was sudo chown -R hlolli /nixand the error went away.

zhengqunkoo · 2019-11-13T18:09:41Z

Different operating system, but logging in again allows connectino to daemon on Linux. Problem was probably due to unset permissions.

zhujinxuan · 2019-12-09T21:58:05Z

Same problem happens in Catalina. But the problem is in the mac's side that the mac mounts / as read only.

Solution for me:

sudo mount -uw /

domenkozar · 2019-12-18T14:27:46Z

Seems like on macos the daemon takes some time to reload, so you can see this error for about 10s before it boots up.

domenkozar · 2019-12-18T14:30:25Z

I am also having this issue on Fedora 37. Reboots have not worked. A reinstall did, for a while, but the issue has popped up again.

alessandrocandolini · 2023-08-02T09:59:46Z

I'm also getting this issue on mac os every time I try to upgrade the nix installation following the guidelines here https://nixos.org/manual/nix/stable/installation/upgrading.html I always need to re-install nix from scratch, which is quite annoying. Anyone has an idea why this is happening and how to prevent it?

jonasschultheiss · 2023-08-29T13:44:39Z

same @alessandrocandolini, thats currently my problem. what do you mean by re-installing from scratch?

jonasschultheiss · 2023-08-29T13:46:41Z

ah nevermind, just had to restart my mac

dbaynard · 2023-11-05T21:40:19Z

I hit the issue on darwin with error: cannot connect to daemon at '/nix/var/nix/daemon-socket/socket': Connection refused — in my case, because of a broken upgrade. I've been able to fix this (copying a plist file from the nix store to /Library/LaunchDaemons/) but it is then deleted on an upgrade.

Edit: found a fix for the deletion on upgrade, following #6499 (comment) — replace nix.nixDaemon = true; with services.nix-daemon.enable = true;.

I switched to a configuration that attempted to override some of the org.nix.nix-daemon plist keys, and the resulting plist file contained only the Label and the overridden key.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>org.nixos.nix-daemon</string>
    <key>SoftResourceLimits</key>
    <dict>
        <key>NumberOfFiles</key>
        <integer>10240</integer>
    </dict>
</dict>
</plist>

Plist xml is noisy; here's a simpler representation.

{ Label = "org.nixos.nix-daemon"
, SoftResourceLimits.NumberOfFiles = 10240
}

No matter what I tried, I was unable to load the file; here's an example.

> sudo -i sh -c 'launchctl load /Library/LaunchDaemons/org.nixos.nix-daemon.plist'
Load failed: 5: Input/output error
Try running `launchctl bootstrap` as root for richer errors.

(I never saw a richer error.)

I ended up manually copying the relevant plist file from the nix store (via a profile link) to /Library/LaunchDaemons.

sudo install -m 444 \
  /nix/var/nix/profiles/default/Library/LaunchDaemons/org.nixos.nix-daemon.plist \
  /Library/LaunchDaemons/org.nixos.nix-daemon.plist

This worked; here's the contents of the plist file.

{ EnvironmentVariables.OBJC_DISABLE_INITIALIZE_FORK_SAFETY = "YES"
, KeepAlive = True
, Label = "org.nixos.nix-daemon"
, ProgramArguments =
  [ "/bin/sh"
  , "-c"
  , "/bin/wait4path /nix/var/nix/profiles/default/bin/nix-daemon && exec /nix/var/nix/profiles/default/bin/nix-daemon"
  ]
, RunAtLoad = True
, SoftResourceLimits.NumberOfFiles = 1048576
, StandardErrorPath = "/var/log/nix-daemon.log"
, StandardOutPath = "/dev/null"
}

With that, the launchctl load command worked.

However, as soon as I switched to the new configuration, the org.nixos.nix-daemon service was removed — and ~~I'm not sure why.~~ that required a change from nix.nixDaemon = true; to service.nix-daemon.enable = true;.

fundon · 2023-11-12T12:11:37Z

@dbaynard thanks.

I used nix.nixDaemon = true; that will broke the daemon service.

ryan4yin · 2023-12-28T02:18:35Z

Same error here, and found I have a process that ran out of my cpu, which caused nix-daemon failed to response...
after killing that process, all things works just fine.
