how to solve this
You are using pip version 22.0.3; however, version 22.0.4 is available. You should consider upgrading via the '/home/appuser/venv/bin/python -m pip install --upgrade pip' command.
Hi @cousins, welcome to the community!!
Fortunately, there is nothing to solve. What you are seeing is a benign log message/warning by pip, which you can feel free to ignore.
