Comment 6 for bug 1808875

Thanks for your help. I got past that error but now I am continually encountering another one. When I type install pythia8, it runs for about 5 mins then says:

In file included from main93.cc:9:0:
/users/h2/sclark/CMSSW_10_1_0/MG5_aMC_v2_6_4/HEPTools/pythia8//include/Pythia8Plugins/HepMC2.h:17:32: fatal error: HepMC/IO_BaseClass.h: No such file or directory
 #include "HepMC/IO_BaseClass.h"
                                ^
compilation terminated.
Makefile:174: recipe for target 'main93' failed
make: *** [main93] Error 1
sed: couldn't write 39 items to stdout: Disk quota exceeded
 Finished PYTHIA8 installation

I have run "install pythia8" a few times and I have even tried completely restarting by deleting the mg5 directory, reinstalling everything, but I seem to always encounter this error. Any idea where it may be coming from?
