6 years ago Hey!
I see your environment is set up alright. Could you try something I am going to suggest so that I get a better insight into the issue, because I think that before the compilation is done (line no. 8), the instance contract is being called (line no 16). Actually that is the reason I have introduced delays so that such issues don't come up. Instead of running the init.js file, try running the code in the node console, executing each line in order as given below. Respond with the results, the error if it's unsuccessful.

var web3 = require('web3');
var fs = require('fs');
var solc = require('solc');
web3 = new web3(new web3.providers.HttpProvider("http://localhost:8545"));
code = fs.readFileSync('kyc.sol').toString();
contract = solc.compile(code);
abiDefinition = JSON.parse(contract.contracts[':kyc'].interface);
byteCode = contract.contracts[':kyc'].bytecode;
kycContract = web3.eth.contract(abiDefinition);
deployedContract = kycContract.new({data: byteCode, from: web3.eth.accounts[0], gas: 4700000});
contractInstance = kycContract.at(deployedContract.address);
console.log(contractInstance.address);

Hi, Configured all the prerequisites, node v = 9.5, npm v= 5.6.0 when I am trying to invoke the "node init.js" command from the root directory then facing the below issue:
