Error when running examples: "cannot import name 'Mapping' from 'collections'"

[jrentsch]

Using the first example:

`from bananopie import *

rpc = RPC("https://kaliumapi.appditto.com/api")`

Yields the following:

Using:

• Python 3.11.4
• pip 23.1.2

Hmm, thanks for the report. Looks like some dependency thing - I'll take a look.

@jrentsch I think you need to update urllib3, which is a dependency of requests, which is a dependency of this library: https://stackoverflow.com/questions/71632325/cannot-import-name-mapping-from-collections-on-importing-requests

pip install urllib3 --upgrade

[stjet]

Let me know if that doesn't fix it, but I think it should. On my end I don't have any min version for "requests" specified, so my hypothesis if you already installed requests or urllib3 before, but an older version, that doesn't work after python 3.10. Bananopie has requests (and therefore urllib3) as dependencies, but doesn't have any version requirements for them, so the system just uses the old version (?).
