[Rivet] "The rivet Python module could not be loaded" error

[Fabricio Jiménez]

Hello,

I’m contacting you directly since the “open tickets” page under rivet’s hepforge site gives an error.

I am trying to install rivet in a CERN machine (lxplus6 with afs) in my local directory, following the steps here: https://rivet.hepforge.org/trac/wiki/GettingStarted.

It seems like there is an issue setting the some variables:

[fajimene at lxplus0126 rivet]$ source /afs/cern.ch/user/f/fajimene/Thesis/rivet/local/rivetenv.sh
[fajimene at lxplus0126 rivet]$ rivet --help
The rivet Python module could not be loaded: is your PYTHONPATH set correctly?

Here are the variables:

[fajimene at lxplus0126 rivet]$ echo $PYTHONPATH
/afs/cern.ch/user/f/fajimene/Thesis/rivet/local/lib/python2.6/site-packages

[fajimene at lxplus0126 rivet]$ echo $LD_LIBRARY_PATH
/afs/cern.ch/user/f/fajimene/Thesis/rivet/local/lib:/afs/cern.ch/user/f/fajimene/Thesis/rivet/local/lib:/afs/cern.ch/sw/lcg/external/HepMC/2.06.06/x86_64-slc6-gcc46-opt/lib:/afs/cern.ch/sw/lcg/external/fastjet/3.0.3/x86_64-slc6-gcc46-opt/lib:@YAML_CPPLIBPATH@:/usr/lib:/afs/cern.ch/user/f/fajimene/Thesis/rivet/local/lib:/afs/cern.ch/user/f/fajimene/Thesis/rivet/local/lib:/afs/cern.ch/sw/lcg/external/HepMC/2.06.06/x86_64-slc6-gcc46-opt/lib:/afs/cern.ch/sw/lcg/external/fastjet/3.0.3/x86_64-slc6-gcc46-opt/lib:@YAML_CPPLIBPATH@:/usr/lib:/afs/cern.ch/user/f/fajimene/Thesis/rivet/local/lib:@YAML_CPPLIBPATH@:/afs/cern.ch/user/f/fajimene/Thesis/rivet/local/lib:@YAML_CPPLIBPATH@:/afs/cern.ch/user/f/fajimene/Thesis/rivet/local/lib:/afs/cern.ch/user/f/fajimene/Thesis/rivet/local/lib:/afs/cern.ch/sw/lcg/external/HepMC/2.06.06/x86_64-slc6-gcc46-opt/lib:/afs/cern.ch/sw/lcg/external/fastjet/3.0.3/x86_64-slc6-gcc46-opt/lib:@YAML_CPPLIBPATH@:/usr/lib:

Thank you very much for your help,
