布朗尼部署文件：'OpenZeppelin/openzeppelin-contracts@4.3.1/Address‘平面文件？

Question

有人能帮我理解这个错误吗。为了上下文。我有两个合同，一个会验证，另一个不会。当我试图将它们合并为一个合同时，我注意到了这一点。没有验证的合同是一个ERC1155。

我在brownie页面上看到，扁平oz文件可以很好地解决这个问题。我的问题是，你如何处理文件后，它的弗拉维斯特？我所有的进口品现在都是本地进口了吗？我以前没见过这个，所以我想还有别的办法。我试着在以太扫描时使用doesnt文件进行手动验证，但是它不起作用。我是否需要安装硬帽子或松露只是为了验证？？不过，如果有人能更好地解释这件事，就会被接受。就像为什么单独部署和验证合同一样，但是当将它们合并成一个合同时，它就无法进行验证。
