无法使用 Truffle 部署 ERC20 代币

问题描述

我想使用 Truffle 将遵循“StandardERC20”令牌部署到 kovan 测试网络。我想部署相同的合同 “https://etherscan.io/address/0x69d9905b2e5f6f5433212b7f3c954433f23c1572#code”给 kovan。但是我遇到了跟随错误。我添加了错误日志和部署此令牌所需的一些文件。我发现错误在“ServiceReceiver(receiver).pay{value: msg.value}(serviceName);” ServicePayer.sol。 2_deploy_token.js中deploy函数的最后一个地址参数是我的钱包地址。这是对的吗？我尝试使用混音。但我无法部署它。我可以为这个错误做什么？大家帮帮我！ -错误日志-
