I can deploy my contract on Remix (Javascript VM and Rinkeby), but if I try to use truffle develop and migrate, I am getting an error: Error: Exceeds block gas limit. The gas used in Remix is 3585084.
How can I make it work in truffle?
Try manually setting the gas limit in your truffle.js file for your development network:
development : {
...
gas: 4612388
}

1This works, but there is still another limit that seems hardcoded around 6700000 gas. – rhlsthrm Mar 5 '18 at 16:49

3As of Jan 2019, the hardcoded gas limit in
ganache-cliis 6721975. – Paul Razvan Berg Jan 17 '19 at 12:04 -
which trufflecode /home/user/.nvm/versions/node/v8.11.1/bin/trufflecrtl+f 6721975 – Barrard Jan 22 '19 at 12:48
The gas parameter in truffle.js is NOT the chain's block gas limit. It means maximum to pay for deploys.
So doesn't matter how big you set the number as long as a actual gas required is larger than the hardcoded chain block gas limit you will get the same error again and again!
Here's my answer:
Truffle contract deployment either exceeds block gas limit or out of gas
Hope it helps.
You can check your maximum gas limit with web3.eth.getBlock("pending").gasLimit command in truffle develop console.
Example:
truffle(develop)> web3.eth.getBlock("pending").gasLimit
6721975
That is the maximum number you can set in truffle.js
module.exports = {
networks: {
development: {
host: "localhost",
port: 8545,
gas: "6721975",
network_id: "*" // Match any network id
}
}
};

I solved it and now can run mocha ganache tests without truffle. Solidity Exceeds block gas limit during Mocha Tests with Ganache-cli
