Hi did you work it out I have same message. I am also a beginner trying to install HACS. It is in the home assistant so have downloaded but nothing. Quite frustrating
Cheers Andy Scotland

follow these instructions for your HA installation method

Hi Francis
I am running the latest home assistant software and have followed
These instructions. HACS appears in my custom components. I have tried restarting and making sure browsers are clear. Do you have anything else I can try
Cheers Andy Scotland

And you still get that error when adding the integration ?

Yes I still get that message. Tried reinstalling after renaming old Hacs but still no luck.
Cheers

You have something like this ?

The only thing in components is HACS
And within it has _init_py
Base.py
config_flow.py
Const.py
Data_client.py
Diagnostics.py
Entity.py
