Error: Migration invalid or does not take any parameters
I'm getting Error: Migration invalid or does not take any parameters error when deploying my smart contract. Here is the migration script.
const Migrations = artifacts.require("Migrations");
module.export = function(deployer) {
deployer.deploy(Migrations);
};
Why is this error?
The error “Error: Migration invalid or does not take any parameters” in Truffle indicates a problem with one of your migration scripts while attempting to deploy a smart contract. Truffle migrations are scripts responsible for deploying and configuring smart contracts onto the Ethereum blockchain.
Here’s a breakdown of the components of the error
Error: Indicates that there is a problem or inconsistency.
Migration invalid or does not take any parameters: Specifies the nature of the error. Truffle migration scripts must adhere to certain conventions, and this error suggests that a migration script is either not correctly defined or is not following the expected pattern.
To address this error, consider the following steps
Check Migration Scripts: Review your Truffle migration scripts (files located in the migrations
directory) to ensure they are correctly structured and adhere to the Truffle migration conventions.
Ensure Correct Syntax: Verify that your migration script uses the correct syntax and structure. A typical migration script follows a pattern like this:
const MyContract = artifacts.require("MyContract");
module.exports = function(deployer) {
deployer.deploy(MyContract);
};
Ensure that your migration script has similar structure and is deploying the correct contract.
Verify Dependencies: Ensure that any dependencies or external contracts your contract relies on are correctly imported and deployed in previous migration scripts.
Update Truffle: Ensure you are using an up-to-date version of Truffle. You can update Truffle by running:
npm install -g truffle
Debugging: If the issue persists, use Truffle’s debugging capabilities. Run the migration with additional verbosity using:
truffle migrate --reset --verbose-rpc
This can provide more information about the error.
By carefully reviewing and correcting your migration scripts, you can resolve the “Error: Migration invalid or does not take any parameters” issue in Truffle.

Check misspelled module.export. The correct code should be
const Migrations = artifacts.require("Migrations"); module.exports = function(deployer) { deployer.deploy(Migrations); };
