一. 配置链信息

在truffle-config中

      provider: function() {
          return new HDWalletProvider("钱包私钥", "RPCURL") },
      network_id: 97,
      chain_id:97,
      gasPrice: 10000000000000, 
      gas:50000000,
      websockets: true,
      timeoutBlock:1000,
     },

详细配置说明

二.遇到问题

执行以下命令 truffle compile truffle migrate --network bsctest

===========================

解决方案: 方案一: truffle migrate --network bsctest --rpc.txfeecap 0 --rpc.gascap 0 (失败)参考资料

方案二:更改配置

      provider: function() {
          return new HDWalletProvider("XXXXX",
          "https://data-seed-prebsc-2-s2.bnbchain.org:8545") },
      network_id: 97,
      chain_id: 97,
      gasPrice: 20e10, 
      gas: 25e6,
      websockets: false,
      timeoutBlock: 1000,
     },

中的gas 直接去掉
