关于坚固性和openzepelin的版本问题 [英] Versioning issues with solidity and openzeppelin
本文介绍了关于坚固性和openzepelin的版本问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试在刚刚收到的项目中运行truffle test。
我在谷歌上搜索了TypeErrors，发现可能是由于使用了错误的可靠性，所以我尝试将安装了最新版本的ethers降级为5.0.31，但没有成功，因为我收到了相同的错误。
据我所知，有两个问题-一个是由于我使用的是M1，另一个是由于坚固版本？
我的包裹要求是；
"dependencies": {
"@opengsn/contracts": "^2.2.2",
"@openzeppelin/contracts": "^4.1.0",
"ethers": "^5.0.29",
"truffle-hdwallet-provider": "^1.0.17"
},
"devDependencies": {
"chai": "^4.3.0",
"openzeppelin-test-helpers": "^0.5.1",
"truffle-flattener": "^1.6.0"
}
以下是错误消息：
> truffle test

更新
我已经设法摆脱了关于请求的图像错误的第一个警告，查看了我的停靠站图像，这些图像看起来很好，所以我在truffle-config.js中简单地取消了对此的注释：
compilers: {
solc: {
version: '0.8.0',
// docker: true,
// settings: {
// optimizer: {
// enabled: false, // Default: false
// runs: 200, // Default: 200 | consensys default 0
// },
// },
},
},
感谢@Yilmaz的大方向。我还尝试在版本中添加一个范围，version: ">=0.4.22 <0.9.0"，但没有产生任何影响。
现在，我仍然可以使用TypeError。
更新%2
似乎是GSN合同BaseRelayRecipient.sol的罪魁祸首。合同最近似乎已升级，取而代之的是ERC2771Recipient，我不知道更新我收到的合同的实际工作方式，因此目前我不会升级GSN，但会继续尝试使其工作...
function _msgSender() internal override virtual view returns (address payable ret) {
if (msg.data.length >= 20 && isTrustedForwarder(msg.sender)) {
// At this point we know that the sender is a trusted forwarder,
// so we trust that the last bytes of msg.data are the verified sender address.
// extract sender address from the end of msg.data
assembly {
ret := shr(96,calldataload(sub(calldatasize(),20)))
}
} else {
return msg.sender;
}
}
最后一个返回给TypeError: Return argument type address is not implicitly convertible to expected type (type of first return variable) address payable.
但是...我无法更改BaseRelayRecipient...？我知道这个安装程序几个月前还在运行。
推荐答案
如果您没有告诉Truffle您使用的是哪个版本，则Truffle将使用默认版本0.5.16
在turffle.config.js中
compilers: {
solc: {
// whatever version you are using
version: "0.8.4",
// you could also put a range here
// version: ">=0.4.22 <0.9.0",
}
}
