Truffle: Contract deployment using truffle and Ganache: out of gas

[billieluxu]

---

Issue

I tried to use truffle connected to Ganache to deploy my contract which imports two other contracts but does not initialise any of these two imported contracts upon deployment. Truffle kept on reporting the error "out of gas". But no matter how high the attached gas is (also adjusted the ganache chain gas limit and truffle.js gas parameter to allow higher transaction gas), I always get the same error: out of gas.

In reality the contract deployment should never consume that much gas. I used Remix to deploy the same contract locally and to Rinkeby using MetaMask, both were successful. Gas consumed was very standard, nothing shockingly high.

Steps to Reproduce

Since the contracts are not open to the public, I cannot share all the contracts. But once I include these two functions(at the same time) in the contract that I was trying to deploy, then I get the error "out of gas" no matter how high I set the gas with the deployment transaction.

`function createUser(address AccountOwner, string userID, string firstName, string secondName, string userAddress, string _email, string phone) public isRegulator() isCSD() returns (address){
User newUser = new User(Regulator, address(this), AccountOwner, userID, firstName, secondName, userAddress, _email, phone);

    users.push(address(newUser));

    userCreated(address(newUser), firstName, secondName);

    return address(newUser);
}

function createEntity(string entityID, address entityOwner, string entityName, string entityCode, string entityAddress, string _email, string phone) public isRegulator() isCSD() returns (address){
    Entity newEntity = new Entity(Regulator, entityOwner, entityID, entityName, entityCode, entityAddress, _email, phone);

    entities.push(address(newEntity));

    entityCreated(address(newEntity), entityName);

    return address(newEntity);
}

`

Expected Behavior

Deployment successful. The transaction gas used returned by Remix(connected to Rinkeby) is 5063223.

Actual Results

Below is the error message from truffle:

Environment

• Operating System: MacOS
• Ethereum client: Ganache
• Truffle version (truffle version): v4.1.14
• node version (node --version): v6.3.1
• npm version (npm --version): 3.10.3

I had the same problem and this solved my issue.

1. Add solc compiler optimization to your truffle.js

module.exports = {
  networks: {
    development: {
      host: "127.0.0.1",
      port: 8545, // ganache-cli
      //port: 7545, // ganache ui
      network_id: "*" // Match any network id
    }
  },
  solc: {
    optimizer: {
      enabled: true,
      runs: 200
    }
  }
};

1. Recompile all of your contracts to get the optimized versions

truffle compile --all

1. Migrate to Ganache

truffle migrate --reset

I also upgraded to the latest beta version of truffle as it has a much nicer output and debugging enhancements, etc. You don't have to do this but just in case you want to.

npm uninstall -g truffle
npm install -g truffle@beta

I hope this helps!

@rsamo Thanks Ryan! I had the same problem and that fixed it.

Glad I could help @roschler!

[luckyyang]

@rsamo That really helps, thank you!

[gnidan]

Seems like this is not a problem anymore. Closing for issue maintenance! Thanks everyone!

FYI I just had the same problem and your suggestion @one70six fixed it. I got it down to a single, innocuous line in my solidity code where if it was commented out the contract deployed, but if I uncommented it it said OOG (even though I have ganache set to 10b gas). But, fixed now, fortunately.
