const INFURA_PROJECT_ID = "3dxxxx";
const ROPSTEN_PRIVATE_KEY = "e6xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

module.exports = {
  networks: {
    ropsten: {
      url: `https://ropsten.infura.io/v3/${INFURA_PROJECT_ID}`,
      accounts: [`0x${ROPSTEN_PRIVATE_KEY}`]
    }
  }
};

根据网站上的示例，我将合同部署到了ropsten，但报告了一个错误。私钥大于32位
