Change gas amount in Truffle 4

Question

In Truffle 4, I am performing the migration in truffle develop by using the migrate command in the console.

However it gives the error

Error: The contract code couldn't be stored, please check your gas amount.

How can the gas used be changed? I think it requires editing truffle.js? What is the name of the network created when using truffle develop which gives testrpc listening to port 9545?

Answer 1

You can change the gas provided in truffle.js. Also, have in mind that truffle 4 has the optimizer turned off by default, so you'll probably want to turn it on if the contract still doesn't get deployed.

module.exports = {
  networks: {
    development: {
      host: "localhost",
      port: 8545,
      network_id: "*", // Match any network id
      gas: 4500000
    }
  },
  solc: {
    optimizer: {
      enabled: true,
      runs: 200
    }
  }
};
