   string message;

   constructor() public {

   message = "Hello, World";

   }
   function getGreetings() public view returns (string memory)
   {
     return message;
   }
   function setGreetings(string memory _message) public{
     message = _message;
   }

}

var Hello = artifacts.require("./Hello.sol");
module.exports = function(deployer) {
   deployer.deploy(Hello);
};

Answer 1

SO the Problem was in my genesis block, I wrote genesis.json myself so some parameters were missing. then I used puppeth to create new genesis block and that how i solve.

Answer 2

Indeed adding

"byzantiumBlock": 0,
"constantinopleBlock": 0

to genesis.json fixed the problem for me, as the SHR opcode is a recent addition to geth in the Constantinople release (and byzantiumBlock must be added in order to add constantinopleBlock).

Answer 3

if you successfully migrated before..

Delete all files in --> truffle/build/contracts
