对于以下truffle-config.js文件,其中有module.exports(开发和ropsten)中列出的2个网络,如果我在终端中使用命令 truffle migrate 而没有明确说明 - 网络开发或 - network ropsten ,合同将部署到哪个网络?既?
require('dotenv').config();
const Web3 = require("web3");
const web3 = new Web3();
const WalletProvider = require("truffle-wallet-provider");
const Wallet = require('ethereumjs-wallet');
const ropstenPrivateKey = new Buffer(process.env.ROPSTEN_PRIVATE_KEY, "hex")
const ropstenWallet = Wallet.fromPrivateKey(ropstenPrivateKey);
const ropstenProvider = new WalletProvider(ropstenWallet, `https://ropsten.infura.io/${process.env.INFURA_ROPSTEN_ID}`);
module.exports = {
networks: {
development: {
host: "127.0.0.1",
port: 7545,
network_id: "*" // Match any network id
},
ropsten: {
provider: ropstenProvider,
gas: 4600000,
gasPrice: web3.utils.toWei('55', 'gwei'),
network_id: "3"
}
}
};
答案 0 :(得分:0)
如果未指定--network
,则仅部署development
。您只需运行迁移即可确认:
$ truffle migrate
Compiling .\contracts\SimpleContract.sol...
Writing artifacts to .\build\contracts
Using network 'development'.
Network up to date.
