This isn’t quite right, you’ve added libraries to the binaries path and added binaries to the python library path. I’d suggest using an environment module for each version of ROOT that you have installed:
The environment module should look something along the lines of this (which should be similar to what would go in your bashrc):
#%Module1.0
conflict root
set version 6.14.04
set prefix /opt/root/${version}
setenv ROOTSYS ${prefix}
append-path LIBRARY_PATH ${prefix}/lib
append-path PYTHONPATH ${prefix}/lib
append-path CMAKE_PREFIX_PATH ${prefix}
append-path JUPYTER_PATH ${prefix}/etc/notebook
append-path PATH ${prefix}/bin
