When I try running rails console I get this error:
rails console
/Users/TuzsNewMacBook/.rvm/gems/ruby-2.3.7/gems/bootsnap-1.3.2/lib/bootsnap/load_path_cache/core_
can you try
cd /usr/local/opt/readline/lib ln -s libreadline.8.dylib libreadline.7.dylib
you are on the right track but it seems like rails is looking for libreadline.7.dylib and libreadline.7.dylib is not there in the folder.
