Put the line to modify PATH in ~/.profile, or in ~/.bash_profile if that's what you have. On macOS, you may need to use ~/.zprofile instead, even if it doesn't already exist. In all these cases, you must log out and then back in for changes to take effect.

The profile file is read by login shells, so it will only take effect the next time you log in. (Some systems configure terminals to read a login shell; in that case you can start a new terminal window, but the setting will take effect only for programs started via a terminal, and how to set PATH for all programs depends on the system.)

NOTE: You need to restart your terminal session, otherwise the changes won't take effect.
