Correct way to install perl-anyevent-i3?

Correct way to install perl-anyevent-i3?

[Chris Keschnat via]

Hello,
I have =i3-wm= installed via a package under =operating-system=.
Calling =i3-save-tree= gives the following error:

#+begin_src sh

  $ i3-save-tree
  Can't locate AnyEvent/I3.pm in @INC (you may need to install the AnyEvent::I3 module) (@INC contains: /gnu/store/hy6abswwv4d89zp464fw52z65fkzr7h5-perl-5.34.0/lib/perl5/site_perl/5.34.0/x86_64-linux-thread-multi /gnu/store/hy6abswwv4d89zp464fw52z65fkzr7h5-perl-5.34.0/lib/perl5/site_perl/5.34.0 /gnu/store/hy6abswwv4d89zp464fw52z65fkzr7h5-perl-5.34.0/lib/perl5/5.34.0/x86_64-linux-thread-multi /gnu/store/hy6abswwv4d89zp464fw52z65fkzr7h5-perl-5.34.0/lib/perl5/5.34.0) at /run/current-system/profile/bin/i3-save-tree line 19.
  BEGIN failed--compilation aborted at /run/current-system/profile/bin/i3-save-tree line 19

#+end_src

So I added =perl-anyevent-i3= to the package definition (in the =operating-system=).
After a =guix system reconfigure= and a reboot, =i3-save-tree= is still giving the same error.

There seems to be something wrong with the load path
(I don't know perl terminology, but I hope it is clear what I mean).

The locations are as follows:

#+begin_src sh

  $ which i3
  /run/current-system/profile/bin/i3
  $ ls -l /run/current-system
  lrwxrwxrwx 1 root root 50 27.07.2022 15:19 /run/current-system -> /gnu/store/nv9h5bdfyz3hzv11c7c2kaxiiqkv84ds-system
  $ locate I3.pm
  /gnu/store/d3xis9wkrmi2lrpkb61cl31nsyrpm921-perl-anyevent-i3-0.17/lib/perl5/site_perl/5.34.0/AnyEvent/I3.pm

#+end_src

PS: I had started with installing =perl-anyevent-i3= under my normal user. The errors were similar.

I am unsure how to proceed and grateful for any hints.

Thank you
Chris

What happens if you also include perl in the packages field?

You’ll need to add this to the Perl load path, which is controlled with
the PERL5LIB environment variable.  When Perl is installed in the same
profile this variable will be set automatically.

Wow, you guys are fast. Thank you, adding perl to the list solved the issue.
