Error when trying to install homeassistant on DS213

HI All,
So i follow the online guide for installing homeassistant on Syno that doesnt have docker (DS213)
https://www.home-assistant.io/docs/installation/synology/

But i run into trouble installing the multidict when running this :
./python3 -m pip install homeassistant==0.64.3

The error i get. Any help would be appreciated
