When deploying on main net I get "Exceeds block gas limit"

• I’ve asked for help in the Truffle Gitter before filing this issue.

Issue

I ran truffle migrate --network main, with my Geth running the main net. At every step, I would get:

Error encountered, bailing. Network state unknown. Review successful transactions manually.
Error: Exceeds block gas limit

Steps to Reproduce

Do truffle migrate targeting the main net.

Expected Behaviour

I would have thought that a reasonable amount of gas would be given to the transactions.

Actual Results

• When it did deployer.deploy(Migrations); I got this block gas limit error.
• So I changed the line to deployer.deploy(Migrations, { gas: 300000 });
• Then when it did, behind the scenes, migrations.setCompleted(1), again I got block gas limit.
• So I did this .setCompleted(1) by hand within Geth
• Then when it did deployer.deploy(MyContract); I got this block gas limit error.
• So I changed the line to deployer.deploy(MyContract, { gas: 300000 });
• Then when it did, behind the scenes, migrations.setCompleted(2), again I got block gas limit.
• So I did this .setCompleted(2) by hand within Geth

On my Geth console, I noticed the following:

> eth.getBlock("pending").gasLimit
4709181
// Wait for a block
> eth.getBlock("pending").gasLimit
4704588

Your value (500000) seems rather low. The default value is 4712388. Try with the default or lower it to 4612388. Not sure why but it then worked on my end…

I had the same issue with truffle 4.0.1

this is my workaround

$ truffle console
truffle(development)> web3.eth.getBlock("pending").gasLimit
6712390

then in the truffle.js:

module.exports = {
  networks: {
    development: {
      host: "localhost",
      port: 8545,
      gas: 6712390,
      network_id: "*" // Match any network id
    }
  }
};
