我实际上正在学习以太坊上的智能合约编程,并且使用松露。现在我在这里制作本教程:https ://truffleframework.com/tutorials/building-dapps-for-quorum-private-enterprise-blockchains
您可以在其中学习如何创建具有法定人数的 dapp。但现在我有一个问题。
我完全按照描述做了所有事情,但是当我这样做时:
truffle migrate
我在这里收到此错误:
$ truffle migrate
⚠️ Important ⚠️
If you're using an HDWalletProvider, it must be Web3 1.0 enabled or your migration will hang.

Truffle v5.0.1 (core: 5.0.1)
Node v8.11.4
现在不知道为什么...
有没有人有同样的问题,可以在这里帮助我吗?
这是我的智能合约:
pragma solidity ^0.4.17;
contract SimpleStorage {
uint public storedData;
constructor(uint initVal) public {
storedData = initVal;
}
function set(uint x) public {
storedData = x;
}
function get() view public returns (uint retVal) {
return storedData;
}
}
还有我的 truffle-config.js 文件:
module.exports = {
networks: {
development: {
host: "127.0.0.1",
port: 22000, // was 8545
network_id: "*", // Match any network id
gasPrice: 0,
gas: 4500000
},
nodefour: {
host: "127.0.0.1",
port: 22003,
network_id: "*", // Match any network id
gasPrice: 0,
gas: 4500000
},
nodeseven: {
host: "127.0.0.1",
port: 22006,
network_id: "*", // Match any network id
gasPrice: 0,
gas: 4500000
}
},
// Set default mocha options here, use special reporters etc.
mocha: {
// timeout: 100000
},
// Configure your compilers
compilers: {
solc: {
version: "0.4.25", // Fetch exact version from solc-bin (default: truffle's version)
}
}
}
和迁移文件:
var SimpleStorage = artifacts.require("SimpleStorage");
module.exports = function(deployer) {
// Pass 42 to the contract as the first constructor parameter
deployer.deploy(SimpleStorage, 2, { privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="] })
};
