尝试使用松露编译合同时出现 Pragma Solidity 错误

如何解决尝试使用松露编译合同时出现 Pragma Solidity 错误

我希望你们中的一个能帮助我解决我做错的事情:)。每次尝试使用 truffle 编译时都会出现此错误

Truffle v5.3.9 (core: 5.3.9)
Node v14.17.0

/C/Users/andre/Desktop/****/core/contracts/Token1.sol:1:1: ParserError: Expected pragma,import directive or contract/interface/library deFinition.
��pragma solidity =0.5.16;

Compilation Failed. See above.

这里是 Token1.sol 文件：

pragma solidity =0.5.16;

import "../node_modules/@openzeppelin/contracts/token/ERC20/ERC20Detailed.sol";
import "../node_modules/@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract Token1 is ERC20Detailed,ERC20 {
    constructor() ERC20Detailed('Token 1','TK1',18) public {}
}

我希望这有意义:) 由于某种原因，我在导入 @openzeppelin 时遇到了一些问题 import "@openzeppelin/contracts/token/ERC20/ERC20Detailed.sol" 对我不起作用，但如果我添加 ".. /node_modules/" 在前面它解决了问题。或者我不确定这是否是我的编译给我错误的原因:)
