我无法理解如何在GovernorVotes 合约中使用IVotes 合约地址

Question

As IVotes is a interface and cannot be deployed.

    IVotes public immutable token;

    constructor(IVotes tokenAddress) {
        token = tokenAddress;
    }
....

Error: *** Deployment Failed ***

"IVotes" is an abstract contract or an interface and cannot be deployed.

• Import abstractions into the '.sol' file that uses them instead of deploying them separately.
• Contracts that inherit an abstraction must implement all its method signatures exactly.
• A contract that only implements part of an inherited abstraction is also considered abstract.

I want to use IVotes address passing in GovernorVotes constructor. I tried bunch of methods but none works

Answer 1

The Solidity snippet, that you shared, expects a contract on the tokenAddress to implement the IVotes interface.

But it needs to be a "full" contract with all function bodies - not just the function declarations.
