This pull request passes --quiet flag to pip uninstall command so it suppresses non fatal warnings on package removal on upgrade (we already pass this flag to pip install during package installation).
I also updated the command line to use -y flag so pip runs in command line and non-interactive mode (should be more robust than piping y to pip stdin).
