Am I doing something wrong? Other dependencies install just fine.

Mycodo version: 8.8.8

Attempted with the stock pip 20.3.1, then repeated after upgrading to pip 20.3.3 --> installation of dependencies failed.

Also attempted again after removing ~/Mycodo/.dependency --> failed.

Whilst trying to set up inputs with CircuitPython dependencies (e.g. ADS1115), I got the following error logs:
