Perl script invocation error from Python

Question

When cmd is run manually it works with no issues, but when run from another program on linux it gives me an error in the logs. Any ideas would be greatly appreciated. thanks

Comes up with this error when in logs when i check log files.

[WARNING ] 17:39:20 core:124 [execute] command 'perl /home/josh/scripts/deluge/sorttv.pl' failed with exit code 1
[WARNING ] 17:39:20 core:128 [execute] stderr: Upon execvpe perl /home/josh/scripts/deluge/sorttv.pl ['perl /home/josh/scripts/deluge/sorttv.pl', '176426f007943621q60bc72d3ae333af46a0d502', 'Continuum Season 2', '/home/josh/media/!complete'] in environment id 25326672

func(file, *argrest)

UPDATE-

now i get a diff error-

[WARNING ] 21:43:00 core:124 [execute] command './home/josh/scripts/deluge/sorttv.pl' failed with exit code 2
[WARNING ] 21:43:00 core:128 [execute] stderr: Can't locate WWW/TheMovieDB.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_perl .) at ./home/josh/scripts/deluge/sorttv.pl line 56.

Iv changed the command on deluge by removing the 'perl' so it now just runs './home/josh/scripts/deluge/sorttv.pl' check above I believe iv installed WWW/TheMovieDB.pm but maybe not correctly — Sarge888

New error: It's expecting module WWW::TheMovieDB to be installed. Install it — ikegami

Could also be a permission problem. What is the full path to TheMovieDB.pm? (perldoc -l WWW::TheMovieDB might give it to you, or you can use find to scour your system) — ikegami
– ikegami, Commented Dec 10, 2013 at 3:13
its located in - /usr/local/lib/perl5/site_perl/5.18.1/WWW/TheMovieDB.pm — Sarge888

You instructed execvpe to look for an executable named perl /home/josh/scripts/deluge/sorttv.pl. As you can imagine, it did not find it.

What you did was equivalent to entering the following in the shell:

'perl /home/josh/scripts/deluge/sorttv.pl' ...

/home/josh/scripts/deluge/sorttv.pl should be passed as an argument. Instead of

args = (...)
os.execvpe('perl /home/josh/scripts/deluge/sorttv.pl', args, env)

You want

args = ('/home/josh/scripts/deluge/sorttv.pl', ...)
os.execvpe('perl', args, env)

I didnt make the script. Im just trying to get it to work with deluge. So the problem lies with deluge or the script?

You need to provide the argument seperately from the command when you call the function in python. As you can see, the executable (perl) should be the first argument to execvpe, and the argument /home/josh/scripts/deluge/sorttv.pl should be the second.
