我刚开始使用 Solidity,为了理解和学习 Solidity 以及与 Remix 的组合,我复制了一些合同。目前我正在测试合约“Token69”,如果我现在尝试部署令牌,我会收到错误消息:

“创建 Token69 错误:错误编码参数:错误:无效的 BigNumber 字符串(argument="value",value="",code=INVALID_ARGUMENT,version=bignumber/5.1.1)"

我发现我的问题的原因是因为构造函数中的数据。我可以毫无问题地删除这些代码部分,还是必须用数据来完成这些部分?除此之外,如果我取出 Constructor 并尝试部署代币(一切都在标准气体限制上并收取 Remix 的所有其他标准值),则代币将永久处于“待创建代币”状态没有错误或错误报告或任何事物。我真的不知道该怎么办。

任何人都可以帮助我吗?


我已经测试了另一个合约,现在我可以部署合约并且代币被发送到我的钱包,但我无法将代币转移到另一个钱包。我在这个合同中找不到问题,有人可以帮我解决这个问题吗?
