I have first executed the command: export LD_LIBRARY_PATH=/usr/local/lib
export LD_LIBRARY_PATH=/usr/local/lib
Then I have opened .bash_profile file: vi ~/.bash_profile
.bash_profile
vi ~/.bash_profile
The file .bash_profile is only executed by login shells. You may need to put it in ~/.bashrc, or simply logout and login again.
~/.bashrc
