How to suppress outdated pip warning

Question

Every pip command ends with a warning:

You are using pip version 18.1, however version 19.3.1 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command.

However, updating pip doesn't work, see below. Can I suppress the warning, and how? Can I update pip, and how?

To upgrade pip on Windows, you may find answers in this thread . This seems to be the solution:

python -m pip install -U --force-reinstall pip

Or to answer your actual question about suppressing pip warnings, pip has the -q/-qq/-qqq option to suppress logging output.
