部署到 rinkeby 测试网时，交易未在 750 秒内挖掘

Question

我正在尝试在 rinkeby 测试网上部署智能合约。 但我不断收到以下错误

   Deploying 'Migrations'
   ----------------------
   > transaction hash:    0x86ad627d53f469648b8a32364572dafd93990c5ccaf839995fba79500875d660
 ** Deployment Failed **

"Migrations" -- Transaction was not mined within 750 seconds, please make sure your transaction was properly sent. Be aware that it might still be mined! -- Reason given: Custom error (could not decode)..


Exiting: Review successful transactions manually by checking the transaction hashes above on Etherscan.

我尝试在 ropsten 上进行部署，它成功了，一切正常。 我使用的 rinkeby 网络设置如下

rinkeby: {
  provider: () => new HDWalletProvider(mnemonic, `https://rinkeby.infura.io/v3/${projectId}`),
  network_id: 4,       // Rinkeby's id
  gas: 10000000,        
  gasPrice: 100000000,  // 1 gwei (in wei) (default: 100 gwei)
  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 )
},

这可能是什么原因？ 提前致谢

Answer 1

交易仍在等待中（现在时间：1663140032）。 您应该检查您设置gasPrice足够高。 只需尝试在部署时设置100 gwei和gasLimit=5000000 。
