library setup fails with space in file path

[rsdefever]

Current behavior

If library_setup.py is executed from a directory with a space in the path to the current location, it fails and exits with an error. Example where working directory is: /root/simulations/test sim

rm: cannot remove '/root/simulations/test': No such file or directory
rm: cannot remove 'sim/nvt.inp': No such file or directory
mv: target 'sim/nvt.inp' is not a directory

Expected behavior

library_setup.py should work correctly regardless of if there is a space in the directory path.
