TypeError: Interfaces cannot inherit. interface AggregatorV2V3Interface is AggregatorInterface, AggregatorV3Interface about brownie_fund_me

I got it to compile in the end, but couldn't get the red warning for my import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol"; line to go away!

Hey Guys!
I found a solution to remove V2V3 and just put V3.
It works.

Hello! Can you indicate where or how you remove V2V3? Thanks!

[themodfunction]

Hey @FCardellino
In almost all places where V2V3 occurs, replace it by just V3

I was having the same problem and was stuck for over 4 hours with this. I was using pragma solidity ^0.8.0; solidity version and compiling on 0.6.0 version. There are some serious problems with the Aggregators to be honest.

Finally, somehow I found a way to compile the MockV3Aggregator as well......

Just use:

 - '@chainlink=smartcontractkit/[email protected]'
 - '@chainlink=smartcontractkit/[email protected]'

Both of these in the Config file....and then you're good to go!

HOPE IT HELPS.
Thanks.

That's really odd....

The 0.2.1 should do the trick...

im having this same issue . cant get the mockV3Aggregator to compile . cant get past that section bc of the issue

Hi @cryptony8055, I solved the issue in this way . I hope it can help you!

[JCDC9919]

Hi @cryptony8055, I'm not sure if it's the "correct way" but I found it seemed to work if you widen the scope of the Solidity versions:
pragma solidity >=0.6.0 <0.9.0;
Using the carrot notation on 0.6.0 seemed to give me further errors
This was using 0.3.0 chainlink in the .config file

hey @JCDC9919 thanks a lot it worked .
