I have unboxed pet-shop. Then inside the contracts folder, I made a file Election.sol which has the code –

pragma solidity ^0.5.8;


contract Election{
    string public candidate;
    constructor() public{
        candidate = "candidate 1"; //state var

    }   
}

Then inside migrations folder, I made 2_deploy_contract.js which has the code –

var Election = artifacts.require("./Election.sol");

module.exports = function(deployer) {
  deployer.deploy(Election );
};

Truffle-config.js –

module.exports = {
  // See <http://truffleframework.com/docs/advanced/configuration>
  // for more about customizing your Truffle configuration!
  networks: {
    development: {
      host: "127.0.0.1",
      port: 8545,
      network_id: "*", // Match any network id
      from:"0xCAEf077F78ce851B21524363753b4A49a4a6D503",
    },
    develop: {
      port: 8545
    }
  }
};

When I do truffle migrate, I get this error. –
truffle migrate

Compiling your contracts…

Everything is up to date, there is nothing to compile.

Migrations dry-run (simulation)

Deploying 'Migrations'

Error: Error: Error: * Deployment Failed *

"Migrations" ran out of gas (using Truffle's estimate.)
* Block limit: 0x50e7c
* Gas sent: undefined
* Try:
+ Setting a higher gas estimate multiplier for this contract
+ Using the solc optimizer settings in 'truffle-config.js'
+ Making your contract smaller
+ Making your contract constructor more efficient
+ Setting a higher network block limit if you are on a
private network or test client (like ganache).
