zigbee2mqtt on FreeBSD as unprivileged user

[petermolnar]

Hi all,

A long time ago I successfully installed zigbee2mqtt on a FreeBSD. I wanted to do the same, but the process is failing on trying to node-gyp serialport. I reported it at serialport/node-serialport#2553 because it happens with mere npm install, but I was wondering if anyone knows the solution to this.

Note: I can install and run npm uninstall --global --unsafe-perms [email protected] as root, but I'd rather not, and even if I do so and it looks healthy, the npm ci command for zigbee2mqtt doesn't seem to pick it up.

It looks like your unprivileged user can't write to its own directory (/opt/zigbee2mqtt), so how are you thinking this will work?

[petermolnar]

I know how it looks like. I'd done numerous chown -R-s before and after trying to compile. I'm not new to linux/BSD.

To me it seems that during the process something changes the owner to a user that is not the current one running the process.

[hmoffatt]

Ah you mention running it in the jail - I guess it's something to do with that then. Otherwise you are just running everything as a simple non-root user, the only explanation is file permissions.

[petermolnar]

I'm not running it in a jail.

May I kindly ask you to try to reproduce it?
It would be nice to see if it's something with my setup or not.

EDIT long story short I didn't see a need for the jail, so I'm running it as an unprivileged user. npm ci should work that way, shouldn't it?

[petermolnar]

Steps:

1. FreeBSD 13.1 up to date
2. as privileged user, pkg install npm git gmake gcc
3. change into an unprivileged user
4. git clone --depth 1 https://github.com/Koenkk/zigbee2mqtt.git ~/zigbee2mqtt
5. cd ~/zigbee2mqtt
6. npm ci

My results:

What are the actual directory permissions?

Perhaps it's an npm bug. The directories it is trying to unlink probably don't even exist yet.

[petermolnar]

# ls -lah | grep zigbee
drwxr-xr-x   11 domoticz  domoticz    28B Nov 12 18:59 zigbee2mqtt

And yes, I don't believe this is a zigbee2mqtt bug, which is why I opened a bug report with serialport. The conversation here is to check if anyone encountered this, and if someone has a solution.

[hmoffatt]

What about the permissions of node_modules and ~/.npm?

[hmoffatt]

I mentioned the jail because the instructions you linked to mention a jail. Sorry I am only using Linux and can't help with reproducing this.
