You are using pip version 19.0.3, however version 19.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
 -- removing any existing file or link
 -- creating symlink to certifi certificate bundle
 -- setting permissions
 -- update complete
codehexaui-iMac:Python 3.7 codehexa$ ./Update\ Shell\ Profile.command 
This script will update your shell profile when the 'bin' directory
of python is not early enough of the PATH of your shell.
These changes will be effective only in shell windows that you open
after running this script.

All right, you're a python lover already

Resolving Dependencies
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).
