Get errors when adding ERC721EnumerableUpgradeable in the Example Contract

[Olive-l]

I am using the example upgradeable contact, and modify some code to add the ERC721EnumerableUpgradeable, like as blow:
abstract contract ExampleERC721Upgradeable is ERC721Upgradeable, DefaultOperatorFiltererUpgradeable, OwnableUpgradeable, ERC721EnumerableUpgradeable
and I override the functions of ERC721EnumerableUpgradeable accordingly. Then I will get the error message:

The detail error message is :

Could somebody help me fix this? thx in advance!

btw, if I removed the ERC721EnumerableUpgradeable, everything works fine

You can remove the import of IERC721Upgradeable from the IERC721EnumerableUpgradeable file, which is imported in ERC721Enumerable; instead of that import IERC165Upgradeable from @openzeppelin/contracts-upgradeable/utils/introspection/IERC165Upgradeable.sol in IERC721EnumerableUpgradeable. This will help you solve your issue.
