        uint256 ethPrice = getPrice();

        return ethAmountInUsd;

    }

}

错误：-

气体估计失败关气体估计错误并显示以下消息（见下文）。事务执行很可能会失败。是否要强制发送？执行恢复

基本上，当我在部署时在我的合约中传递任何 Wei、gwei 或以太币时，我会收到此错误，否则它会被部署。

Answer 1

当你部署你的合约时，你的 constructor 函数被调用，它没有被标记为 payable。

constructor() payable {
    owner = msg.sender;
}

付钱就可以了
