Sending of notifications fails with "OSError: [Errno 2] No such file or directory"

Weechat masterrace here, getting this output when someone mentions me;

Hi. Do you have libnotify installed in your system? You can verify this by running the following command from a terminal:

notify-send --help

If it fails with

notify-send: command not found

then you will need to install it (see README). Let me know if this fixes the issue for you.

Yeah, I haven't installed libnotify, but seems like the website's download section is broken. At least I found it on my distro's apt library but I don't know which one to install, can you inform me about which is needed?

libdesktop-notify-perl - Perl module which communicates with the Desktop Notifications framework
libnotify-bin - sends desktop notifications to a notification daemon (Utilities)
libnotify-cil-dev - CLI library for desktop notifications
libnotify-dev - sends desktop notifications to a notification daemon (Development files)
libnotify-doc - sends desktop notifications to a notification daemon (Documentation)
libnotify0.4-cil - CLI library for desktop notifications
libnotify3.0-cil - CLI library for desktop notifications
libnotify3.0-cil-dev - CLI library for desktop notifications

You need to install libnotify-bin, which provides /usr/bin/notify-send. Let me know if this fixes the issue for you.

I am closing the issue due to inactivity. If the installation of libnotify-bin has not fixed the problem for you, please reopen the issue.

BTW, in 16aeda10ff1589cd9478f5e6af5d43c6f46ed292, I have added printing of a more reasonable error message when sending of a notification fails:

Failed to send the notification via notify-send (reason: 'OSError: [Errno 2] No such file or directory').
Ensure that you have notify-send installed in your system.
