SyntaxError:在硬帽子编译时所期望的数字

Question

这是我正在试图编译的一份合同

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.17;

import "@openzeppelin/contracts/access/Ownable.sol";


contract EscrowView is Ownable {
    uint public feePercent;
    address public feeAddress;

    enum PoolType {
        BUY,
        SELL
    }

    struct EscrowPool {
        PoolType pType;
        address poolCreator;
        address tokenAddr;
        uint amount;
        address[] exchangeTknsAddr;
        uint[] exchangeTknsAmount;
    }
    uint public noOfPools;
    mapping(uint => EscrowPool) public poolsTable;
    
}

这是我的合同的文件名：1.Escrow_view.sol

每当我运行npx hardhat compile时，都会得到以下错误：

Answer 1

当我将合同文件名从1.Escrow_view重命名为Escrow_view时，错误消失了。

不知道为什么会发生这种情况，因为我以前多次这样命名文件，使用一些更漂亮的标准，看起来就像是新版本的“硬帽子”。
