Truffle Migrate SyntaxError: Invalid or unexpected token

Question

I am trying to follow the truffle pet shop tutorial and I am doing my first truffle migration.

After this command:

truffle migrate

I get this error:

SyntaxError: Invalid or unexpected token at new Script (vm.js:74:7) at Object.createScript (vm.js:246:10) at /usr/local/lib/node_modules/truffle/build/webpack:/packages/truffle-require/require.js:96:1 at FSReqWrap.readFileAfterClose [as oncomplete] (internal/fs/read_file_context.js:53:3)

I tried installing the latest truffle, deleting the contract/build folder and compile again, changing the pragma solidity ^0.4.17; to pragma solidity ^0.4.24; to make Adoption.sol pragma version to be consistent with the one on Migrations.sol

Anyone solved this error before?

Answer 1

Solved, the problem that when I named the migrations file as 2_deploy_contracts.js, the name was placed on the file itself. Once I deleted this line, it worked

Answer 2

Same problem here when I was following the tutorial of Dapp University. Deleted the 2_deploy_contracts.js file and it works.

Answer 3

Just delete the 2_deploy_contracts.js file and edit the 1_initial_migration.js.

const Migrations = artifacts.require("Your_contract_name");

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

Answer 4

I had the same problem. I have resolved it by changing the encoding from UTF-16LE to UTF-8

Error:

After adding the following solution, it starts working fine for me

If you are using VSCode then you can change Encoding by using the following:

1) Change encoding, choose the option "Reopen with Encoding"

2) And if you see weird character then type CTRL+Z and save the file

3) Run the command and you are done.
