Question

尝试在测试环境中复制智能合约以进行练习。当我去部署合同时，我收到“语法错误：无效或意外的令牌”。我不得不解决其他一些问题，但似乎无法解决这个问题。有人可以帮忙吗？

2_deploy_contract.js

var Etheremura = artifacts.require("Etheremura");

module.exports = function(deployer) {
  deployer.deploy(Etheremura, 0000000000000000000000000D86C54925E12a52a5929c167f20B989F499b3CB7), 000000000000000000000000000000000000000000000000000000000000005f);
};

Answer 1

在 ) 函数的第二个参数之后有一个多余的右大括号 deployer.deploy()。

您似乎还试图将地址和无符号整数作为 ABI 编码值传递。但是，Truffle deploy() 函数接受 JS 标量 - 而不是 ABI 编码值。

所以你可以这样做：

deployer.deploy(
    Etheremura,
    '0xD86C54925E12a52a5929c167f20B989F499b3CB7', // assuming it's an address
    95 // assuming it's an integer, 5f hex == 95 decimal
);

Answer 2

查看部署函数 deployer.deploy(Etheremura, 0000000000000000000000000D86C54925E12a52a5929c167f20B989F499b3CB7), 000000000000000000000000000000000000000000000000000000000000005f);，您的地址后面有一个不必要的右括号。

同时提供您的地址（如 "0xD86C54925E12a52a5929c167f20B989F499b3CB7"）和整数形式的值。还要确保您提供的地址是有效的以太坊地址。
