ethereum - 无法运行 truffle@2.1.2 migrate --network live。 "Exceeds block gas limit"

Question

我正在使用 truffle@2.1.2 针对 localhost:8545 geth@1.5.9-stable rpc 部署智能合约，使用的账户资金来源为以太币已在 geth 控制台上使用 personal.unlockAccount 解锁。

我还通过 RPC 对远程 Parity 节点进行了相同的尝试，但这是我相当坚持的最新版本。

truffle.js

module.exports = {
  build: {
    "index.html": "index.html",
    "app.js": [
      "javascripts/app.js"
    ],
    "app.css": [
      "stylesheets/app.css"
    ],
    "images/": "images/"
  },
  rpc: {
    host: "localhost",
    port: 8545
  },
  networks: {
    "ropsten": {
      network_id: 3,
      port: 8548, // ssh tunnelled to AWS geth/parity node localhost:8545
      from: "0x4f000Bcf4641E2fDcE85BF26A694b053996850D4"
    },
    "live": {
      network_id: 1,
      port: 8545,
      from: "0x00269400181f1B379784BD8cDF786bb20e91Bdef",
      gas: 4612388,
      gasPrice: 2776297000 // taken from Parity startup log message "Updated conversion rate to Ξ1 = US$42.88 (2776297000 wei/gas)"
    }
  }
};

truffle migrate --network live

我尝试调整gas和gasPrice，但找不到有任何影响的值。

我该如何解决这个问题，或者我应该考虑其他契约(Contract)部署方法吗？

亲切的问候。

Answer 1

我只需在网络配置中设置 gas: 3000000 即可解决此问题。

"live": {
  network_id: 1,
  port: 8545,
  from: "0x00269400181f1B379784BD8cDF786bb20e91Bdef",
  gas: 3000000
}

运行迁移大约需要 0.5 ETH，并且需要几分钟时间。
