第7课:编译器版本错误-> 10:43.16 (完整区块链坚固性课程)

Question

$ /home/ionmind/hardhat-fundme-fcc/node_modules/.bin/hardhat deploy --network rinkeby
Error HH606: The project cannot be compiled, see reasons below.

These files import other files that use a different and incompatible version of Solidity:

  * contracts/test/MockV3Aggregator.sol (^0.8.12) imports @chainlink/contracts/src/v0.6/tests/MockV3Aggregator.sol (^0.6.0)

To learn more, run the command again with --verbose

Read about compiler configuration at https://hardhat.org/config

收到此错误后，我按照视频上的指示修改了hardhat.config.js文件

module.exports = {
  //solidity: "0.8.12",
  solidity: {
    compilers: [{ version: "0.8.12" }, { version: "0.6.0" }],
  },

但是仍然会出现错误，所以我也修改了solhint.js文件中的编译器版本。

{
  "extends": "solhint:recommended",
  "rules": {
    "compiler-version": ["error", "^0.8.12", "^0.6.0"],
    "func-visibility": ["warn", { "ignoreConstructors": true }],
    "var-name-mixedcase": "off",
    "avoid-low-level-calls": "off"
  }
}

但还是会犯错误。

我在测试文件夹中创建了一个单独的AggregatorV2V3Interface文件，在本地导入到MockV3Aggregator.sol &还为每个文件声明了solidity ^0.8.12

//SPDX-License-Identifier:MIT
pragma solidity ^0.8.12;

interface AggregatorInterface {
        //Code Here//
}

interface AggregatorV3Interface {
       //Code Here//
}

interface AggregatorV2V3Interface is AggregatorInterface, AggregatorV3Interface {}

//SPDX-License-Identifier:MIT
pragma solidity ^0.8.12;

import "./AggregatorV2V3Interface.sol";

代码中没有错误或警告，但在试图编译时仍然会遇到相同的错误。我不明白为什么我似乎是唯一一个拥有这个编译器issue.Any帮助的人是值得赞赏的。谢谢!

更新您的可靠版本：

module.exports = {
  //solidity: "0.8.12",
  solidity: {
    compilers: [{ version: "0.8.12" }, { version: "0.6.6" }],
  },
