如何使用 truffle 控制台發送超過 10^15 個 ERC20 令牌？

我正在嘗試測試我的合約，但每次我嘗試發送超過 10^15 時都會收到溢出錯誤，而我知道我的錢包可以發送更多。有什麼解決辦法嗎？

pragma solidity 0.8.0;

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

contract NGE is ERC20 {
   address public owner;
   mapping(address => bool) public haveAccess;
   constructor() ERC20("Neon", "NGE") {
       _mint(msg.sender, 1000000*10**16);
       owner = msg.sender;
   }

   function giveAccess(address to) public returns(bool){
       require(msg.sender == owner, "only the owner can give access to this contract");
       haveAccess[msg.sender] = true;
       return(true);
   }

   function minter(address to, uint256 amount) public{
       require(msg.sender == owner || haveAccess[msg.sender] == true);
       _mint(to, amount);
   }
}

^錯誤資訊和原始命令。

在為交易目的處理 truffle 控制台時，使用字元串值（如地址值），因為數字太大，JavaScript 無法處理。這個問題在openzeppelin論壇上討論過。

代替：

token.approve('0xB8b7E4982b71828Dc1FF9b7e3548CdfFaAD6Afbd', 10**16)

採用：

token.approve('0xB8b7E4982b71828Dc1FF9b7e3548CdfFaAD6Afbd', '100000000000000000')
