尝试更新最新区块时遇到错误

Question

我是区块链新手，我只是想将一个简单的智能合约部署到 ropsten 测试网。我使用了 https://github.com/t4sk/solidity-multi-sig-wallet 中的智能合约代码。我也在使用 truffle develop

提供的帐户

我的松露-config.js:

networks: {
development: {
     host: "127.0.0.1",     // Localhost (default: none)
     port: 8545,            // Standard Ethereum port (default: none)
     network_id: "*",       // Any network (default: none)
    },
ropsten: {
    provider: () => new HDWalletProvider(mnemonic, `https://ropsten.infura.io/v3/${infuraKey}`),
    network_id: 3,       // Ropsten's id
    gas: 5500000,        // Ropsten has a lower block limit than mainnet
    confirmations: 2,    // # of confs to wait between deployments. (default: 0)
    timeoutBlocks: 200,  // # of blocks before a deployment times out  (minimum/default: 50)
    skipDryRun: true     // Skip dry run before migrations? (default: false for public nets )
    },
mocha: {
    timeout: 100000
  },
compilers: {
    solc: {
      version: "0.5.1",    // Fetch exact version from solc-bin (default: truffle's version)
      // docker: true,        // Use "0.5.1" you've installed locally with docker (default: false)
      // settings: {          // See the solidity docs for advice about optimization and evmVersion
        optimizer: {
          enabled: false,
          runs: 200
        },
      //  evmVersion: "byzantium"
      // }
    }
  },

我使用的是 solidity：0.5.1

但是当我尝试使用 truffle migrate --network ropsten 部署它时，我收到以下两个错误

1.

This version of µWS is not compatible with your Node.js build:

Error: Cannot find module './uws_win32_x64_72.node'

同时在ropsten网络上创建了上述智能合约地址0xde674E126884c8F7Ddd94B5013065596b81fEd6d的交易。

编辑 1： 我已经用 wss://ropsten.infura.io/v3/${infuraKey}` 替换了提供者 link 并且第二个问题得到解决但现在它显示另一个错误

它说交易可能仍在被开采，那么我怎么知道我的交易何时被开采？同时我可以调用部署在 ropsten_eth https://ropsten.etherscan.io/address/0xb81478b107d5b08b0f9ce8d0e404701a3d2292a0

上的智能合约的 fuctions/events

Answer 1

此处错误的问题可能是您要访问的地址。我搜索了问题可能是什么，并找到了两个线程，人们已经在其中描述了问题并找到了解决方案。很可能这些选项之一应该有助于解决问题。

第一个解是here。这个想法是用 wss 替换 https。应该是这样的：

testnet: {
  provider: () => new HDWalletProvider(mnemonic, `wss://ropsten.infura.io/v3/${infuraKey}`),
  ...
}

然后我又搜索了一些，发现了类似 this 的内容。 post 的作者说问题可能是由于 DNS 或 slow internet 造成的，并建议在配置中添加两个参数：

testnet: {
  ...,
  networkCheckTimeoutnetworkCheckTimeout: 10000,
  timeoutBlocks: 200
}
