在安全帽合同中导入 openzeppelin 错误

如何解决在安全帽合同中导入 openzeppelin 错误

我正在尝试使用一些 @openzeppelin/contracts 导入来部署合同。

合同：

pragma solidity ^0.8.0;
import "../node_modules/@openzeppelin/contracts/token/ERC721/extensions/ERC721URIStorage.sol";
import "../node_modules/@openzeppelin/contracts/utils/Counters.sol";
import "../node_modules/@openzeppelin/contracts/access/Ownable.sol";

contract EthOrb is ERC721URIStorage,Ownable {
//code
}

Package.json：

{
  "name": "eth-orb-contracts","version": "1.0.0","description": "smart contracts for dapps","main": "hardhat.config.js","scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },"author": "","license": "ISC","devDependencies": {
    "hardhat": "^2.2.0"
  },"dependencies": {
    "@openzeppelin/contracts": "^4.0.0"
  }
}

@openzeppelin/contracts 在我的 node_modules 中，我运行了一个 npm I 再次安装。

预期结果：成功导入 deps。

实际结果： 终端中的错误消息：

编辑： 删除“../node_modules”也不能解决这个问题。

这会导致 lint 错误：

import "@openzeppelin/contracts/token/ERC721/extensions/ERC721URIStorage.sol";
import "@openzeppelin/contracts/utils/Counters.sol";
import "@openzeppelin/contracts/access/Ownable.sol";

错误是：

解决方法

我刚刚遇到了这个问题，并通过将整个“@openzeppelin/contracts”移动到合同编写位置的根来解决它。

示例： 我有一个 Contracts 文件夹，里面有 @openzeppelin 文件夹和 MyContract.sol 文件。 然后我就这样导入了合约：

导入“./@openzeppelin/contracts/token/ERC20/ERC20.sol”；
