这个错误在开发过程中不断重复，无论是在公共(public)测试网还是在有 1 个矿工的私有(private)网络中。这对前者来说是有道理的，因为存在竞争条件 b/w 矿工和 gas 价格上涨可能会有所帮助，但为什么它发生在我的私有(private)网络上，交易很少且采矿难度很低？

我使用 web3js send 方法发送两种类型的交易:

 /** executes contract method by creating transaction
 * @param {string} from - payer address
 * @param {string} to - payee address
 * @param {int} amount - number of tokens
 * @param {string} type - transaction type
 */
transferTokens(from, to, amount, type) {
    if (type === 'transfer_to_admin' || type === 'transfer_from_user') {
        return this.contract.methods.transferFrom(from, to, amount).send({ from })
            .catch((err) => {
                logger.info(err);
                return Promise.reject(err);
            });
    }
    if (type === 'transfer_from_admin') {
        return this.contract.methods.transfer(to, amount).send({ 'from': this.coinbase })
            .catch((error) => {
                logger.info(error);
                return Promise.reject(error);
            });
    }
}

其中transfer和transferFrom是ERC20标准实现的Solidity函数。

有人知道如何避免/处理这个错误吗？

Answer 1

这是以太坊网络及其 fork 的老问题。增加 gas 无济于事，只是以太坊区 block 链的糟糕架构

这个错误不会被修复，如果交易没有被处理就等待一个小时，重复，否则你有在这个狗屎链中发送交易 2 次或更多次的风险
