编译 AggregatorV2V3Interface 会导致 TypeError:接口无法继承。接口我在contract->test下添加了一个文件MockV3Aggregator.sol来部署模拟。但是,当我使用“browniecompile”时,出现以下错误:

您可能会在 Brownie 、 Hardhat 或任何其他开发框架中遇到此错误。当您的代码尝试访问 chainlink 合约时,就会发生这种情况。
Ex - 导入“@chainlink/contracts/src/v0.6/tests/MockV3Aggregator.sol”;
MockV3Aggregator也需要访问其他接口。
