ModuleNotFoundError in Emacs Plugin

[claudio-dalicandro]

Hi!
I am trying to run floobits (floobits-share-dir-public), and I get this error:

Now listening on 34101
[Fri Mar  5 01:50:00 2021]  WARN: Error hitting url https://floobits.com/api/orgs/can/admin: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1124)>

Error getting org list: b"/home/cdali/.asdf/installs/python/3.8.6/bin/python: Error while finding module specification for 'floo.proxy' (ModuleNotFoundError: No module named 'floo')\n"

As you can imagine from the output, I use asdf-vm, so python has a different path, but I don't know if this could actually be the cause... During the installation I have a large number of warnings that I report:

Did I do something wrong with the installation?

I'm having the same issue with Python 3.9 after fixing this other issue locally: #101

I'm using ArchLinux and Emacs master branch but I don't have that many warnings in the installation. May it be something is missing to be set up for the default Python installation?
