Re: [Mojolicious] Systemd "Can't locate Mojo/Base.pm in @INC"
The current working directory in Perl should be retrieved using Cwd, not
$ENV{PWD}. Regardless, putting paths in your program based on CWD is a bug,
since the program could be run with any CWD and that should not change its
behavior. I wrote a similar module to the FindBin interface using the same
method as lib::relative for creating arbitrary file paths relative to the
current file: https://metacpan.org/pod/Path::This
With an up to date Mojolicious, curfile can of course solve both these
problems.

Re: [Mojolicious] Systemd "Can't locate Mojo/Base.pm in @INC"
Thanks to both of you, I managed to get past loading modules while starting
the service from systemd. Now there is another bug regarding relative paths
and I wonder how to solve it, it seems lib::relative might not do the trick
my $homedir = $ENV{'HOME'};
my $cwd = $ENV{'PWD'};
my $log = Mojo::Log->new(path => $cwd . '/log/ccdapi.log', level => 'info');
Use of uninitialized value $cwd in concatenation (.) or string at
/srv/ccdapi/VM01/PROD/v1/ccdapi.pl line 21.
Apr 29 16:16:19 vl-vm-sr824.lb ccdapi[65656]: Can't load application from
file "/srv/ccdapi/VM01/PROD/v1/ccdapi.pl": Can't open file
"/log/ccdapi.log": No such file or directory at
/srv/ccdapi/.perlbrew/libs/perl-5.24.0@ccd
Apr 29 16:16:19 vl-vm-sr824.lb ccdapi[65656]: Compilation failed in require

Cheers !
