I have to download a git python repo and install since the pypi version is not updated.

Normally I would do this:

pip install mypackage
pip install mypackage[redis]

Now I have the repo cloned in the following folder:

/opt/mypackage

So how do I install the below while ensuring that I use the local version, not the pypi version.

pip --flag /opt/mypackage install mypackage
pip --flag /opt/mypackage install mypackage[redis]

There are the pip flags available and I don't see how to accomplish :
