1.不知道是不是巧合，在运行 forge install OpenZeppelin/openzeppelin-contracts --no-commit 这段命令时 可以先运行三次 proxychains forge install OpenZeppelin/openzeppelin-contracts --no-commit,然后打开 cat, 然后在运行一次proxychains forge install OpenZeppelin/openzeppelin-contracts --no-commit就可以了，真的有够无聊的。

离成功越近，离失败越近。。。。

添加了 foundry-devops，可以在 broadcast 目录下创建 run-latest.json

Error: script failed: the path broadcast is not allowed to be accessed for read operations 解决方法： 在 foundry.toml 中添加如下代码： fs_permissions = [ { access = "read", path = "./images/" }, { access = "read", path = "./broadcast" }, ] 小瑕疵：MetaMask 中的 NFT 图片没有加载出来，但是 OpenSea 上可以看到我的 DogieNFT。 离成功又近了一步，呐，离失败又近了一步。

ipfs 可能不是最佳的数据托管位置 原因：如果我是唯一一个已经将此数据保留的 ipfs 节点，而我的节点下线，

VsCode 创建字符串常量时，报错：Expected string end-quote. 解决方案：将字符串合并为一行。 感觉略无聊

心静且细心 好有缘
