How can I tell Poetry to use for installs only the wheels in a given directory?

[halloleo]

I using an offline machine where I have put all wheels necessary for my projects in a directory ~/piprepos.

For pip I made this work by having a ~/.config/pip/pip.conf file with the content:

[global]
no-index = true
timeout = 1
default-timeout = 1
find-links =
    /home/me/piprepos/

Now I can say pip install <package> and when I have the wheel in piprepos, it all works fine.

However when I install stuff via poetry install, Poetry still tries to reach the internet for the packages and eventually times out.

How can I tell Poetry use for installs only the wheels in /home/me/piprepos/?
