Truffle v4 used to deploy the contract successfully, but Truffle v5 truffle migrate command fails.

My process to deploy:

1) delete buidl/ folder

2) truffle compile

3) truffle migrate

Truffle v5

The error I get is:

Error:  *** Deployment Failed ***
"ContractName" ran out of gas. Something in the constructor (ex: infinite loop) 
caused gas estimation to fail. Try:
* Making your contract constructor more efficient
* Setting the gas manually in your config or as a deployment parameter
* Using the solc optimizer settings in 'truffle.js'
* Setting a higher network block limit if you are on a
 private network or test client (like ganache).

at process._tickCallback (internal/process/next_tick.js:68:7)
Truffle v5.0.0 (core: 5.0.0)
Node v10.4.0

My truffle-config.js looks like this:

module.exports = {
  networks: {
    development: {
      host: 'localhost',
      port: 8545,
      network_id: '*',
  compilers: {
    solc: { 
      version: "^0.4.24",
      optimizer: {
        enabled: true,
        runs: 200

Then I installed truffle v4 and tried to migrate the same contract:

1) npm uninstall -g truffle

2) npm install -g truffle@4.1.15

3) delete buidl/ folder

4) truffle compile

5) truffle migrate

And it works. I can deploy it on the rinkeby too.

Remix doesn't deploy it with

javascript VM: "creation of ContractName errored: transaction execution failed"

However, I can deploy it to Rinkeby through Remix

I need this contract to be deployed with truffle v5, because I will develop Solidity 0.5.* contracts that will communicate with the one I am trying to deploy right now, otherwise I won't be able to test with javascript.

The contract I am trying to deploy is: https://github.com/cryptocopycats/awesome-cryptokitties/tree/master/contracts

with couple fixes and additions. Contract starts from KittyCore.sol


Check @goodvibration answer. It should work in most instances.

I don't recommend the answer that I will share below, it will ignore the EIP-170, hopefully there is a better answer

I was only able to make it migrate using: ganache-cli --gasLimit=0x1fffffffffffff --allowUnlimitedContractSize -e 1000000000

--allowUnlimitedContractSize: "Allows unlimited contract sizes while debugging. By enabling this flag, the check within the EVM for contract size limit of 24KB (see EIP-170) is bypassed. Enabling this flag will cause ganache-cli to behave differently than production environments."

-e {number}: gives that much ether to all 10 accounts

My truffle-config.js looks like this:

module.exports = {
  networks: {
    development: {
      host: 'localhost',
      port: 8545,
      network_id: '*',
      gas: 0x1fffffffffffff

Your truffle-config.js file is not correct. Have a look at: https://github.com/trufflesuite/truffle/releases/tag/v5.0.0-beta.0#bring-your-own-compiler

For the correct format for the truffle-config.js file.

  • Instead of saying that the config file is not correct, it would be way more useful if you pointed out what is wrong with it, and provide a fix, instead of referring to a fairly broad documentation where it's hard to figure out what's wrong with it. – Victor Grau Serrat Jan 29 at 3:55
  • I didn't mean to be unhelpful, your truffle-config.js file doesn't seem to be correct. I was just speaking plainly. The documentation is the best place to check, and the correct format is right at the top. Specifically: It's not a valid javascript object for one thing (6 open curly braces, 3 close curly braces) and it should have a format like this: module.exports = { networks: { ... etc ... }, compilers: { solc: { version: <string> // ex: "0.4.20". (Default: Truffle's installed solc) } } }; – Dennison Bertram Jan 30 at 19:09
