【中文标题】“路径”参数必须是字符串类型。收到未定义。未能验证 1 份合同

【英文标题】：The "path" argument must be of type string. Received undefined. Failed to verify 1 contract(s)

【发布时间】：2021-10-03 20:20:04

【问题描述】：

我正在将智能合约部署到 rinkeby 网络，然后尝试验证合约

truffle run verify IzoneMember --network rinkeby

但它不起作用并一直显示此消息，但是我已经安装了 truffle-verify-plugin、react-script 和 cucumber。

PS C:\Users\dohva\Documents\Github Repo\NFT\truffle-starter-kit> truffle run verify IzoneMember --network rinkeby
Verifying IzoneMember
The "path" argument must be of type string. Received undefined
Failed to verify 1 contract(s): IzoneMember

这是我的 package.json

【问题讨论】：

这能回答你的问题吗？ TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type undefined raised when starting react app

感谢您提供的信息，但 react 应用在我身上运行良好

您找到解决此问题的方法了吗？

是的，我有，HDWalletProvider 的代码结构是错误的，但它适用于我观看的 youtube 视频

【参考方案1】：

对我来说，我有我的导入合同，例如，

../node_modules/@openzeppelin

我删除了../node_modules/ 并修复了
