How to update Mopidy extensions?

I have tried the following commands but none seem to actually take effect in updating the extensions:

sudo python3 -m pip install Mopidy-Iris
sudo python3 -m pip install Mopidy-Muse
sudo python3 -m pip install Mopidy-MPD

Is there something I’m doing wrong? What the proper way to update Mopidy extensions?

By default, pip will not do anything if the package is already installed. To make it upgrade to the latest version, you must pass the --upgrade/-U argument, e.g.:

sudo python3 -m pip install -U Mopidy-MPD

Thank you very much. That worked!
