linux - Perl modules not loading correctly when running as non-root user -
i'm running issue perl on linux system.
when installing new modules (as root), have issues running scripts regular user, not able access new module without manually going in , chmod 775'ing module related files , directories.
i performed cpan upgrade, installing several modules new project. now, perl has become unusable regular user, because of errors don't appear permissions related.
for example, following simple script runs fine root, returns error run regular user:
#!/usr/bin/perl use strict; use warnings; use scalar::util; as can see, script literally nothing except attempt load scalar::util module. regular user, returns error:
**list::util object version 1.21 not match bootstrap parameter 1.42 @ /usr/lib64/perl5/dynaloader.pm line 223. compilation failed in require @ /usr/local/lib64/perl5/scalar/util.pm line 22. compilation failed in require @ ./scalar-test.pl line 4. begin failed--compilation aborted @ ./scalar-test.pl line 4** when sudo cpan , try install list::util, back: list::util date (1.42).
clarification: this happening several modules, not 1 example. not appear affect every module upgraded though; it's several though.
the fact root can run scripts says me either there another, underlying permissions issue i'm not seeing, or perl configured different in way root regular account causing not find module.
