I installed sage to: /home/groups/sc/modules/packages/sage/8.0/ (there are the subfolders bin/lib) on CentOS 7 Per module file, I set:
set root /home/groups/sc/modules/packages/sage/8.0
prepend-path PYTHONPATH $root/bin prepend-path LD_LIBRARY_PATH $root/lib prepend-path LIBRARY_PATH $root/lib prepend-path PATH $root/bin prepend-path CPATH $root/include
prepend-path SAGE_ROOT /home/groups/sc/modules/packages/sage/8.0/
However, when I try to start sage via "sage", I receive:
Error: SAGE_ROOT is set to a bad value: SAGE_ROOT=/home/groups/sc/modules/packages/sage/8.0/ You must correct it or erase it and run this script from the SAGE_ROOT or SAGE_ROOT/local/bin/ directory. Error setting environment variables by sourcing '/home/groups/sc/modules/packages/sage/8.0/bin/sage-env'; possibly contact sage-devel (see google/group/sage-devel).
I also tried to go to "cd /home/groups/sc/modules/packages/sage/8.0/bin" and "./sage", but this returns the same error message. If I do not set "SAGE_ROOT", I get the error, that SAGE_ROOT must be set.
What am I doing wrong? Thanks in advance.
