Hey guys, anyone knows what’s wrong?
Been trying to install truffle on my machine today (MacOS latest version), but keep getting this errors in the terminal:

Any help would be greatly appreciated :grinning:

you should create a seperate mint function outside of the constructor and call this after your contract is deployed

#514

yeah this is an annoying error sometimes. to resolve it you should open your terminal as an administrator. i know how to do this on windows you can just right click and the option comes up to open your terminal as the administrator.

however from doing this quick google search a result came up saying that to use a terminal as an admin on mac you simply can

" To run commands with superuser privileges, use the sudo command . sudo stands for superuser do. You’re asked for the password of the current user. You’re asked to enter the password for adminUsername, after which a new shell is opened for that user."

let me know how you get on with this

#515

Hi !!

I have the same problem right now, I don’t understand how I pass the requested params.

Thanks in advance.

is this for the advanced migrations lesson?

#517

can u elaborate a little more onto which params and what context, like for a smart conract function or in the constructor or in migrations etc?

#518

Hi, yes.

This is for the truffle multi-sig wallet assignment to practice using the terminal.
this is final code:

pragma solidity 0.7.5;
pragma abicoder v2;

contract Wallet {
    address[] public owners;
    uint limit;
    
    struct Transfer{
        uint amount;
        address payable receiver;
        uint approvals;
        bool hasBeenSent;
        uint id;
    }
    
    event TransferRequestCreated(uint _id, uint _amount, address _initiator, address _receiver);
    event ApprovalReceived(uint _id, uint _approvals, address _approver);
    event TransferApproved(uint _id);

    Transfer[] transferRequests;
    
    mapping(address => mapping(uint => bool)) approvals;
    
    //Should only allow people in the owners list to continue the execution.
    modifier onlyOwners(){
        bool owner = false;
        for(uint i=0; i<owners.length;i++){
            if(owners[i] == msg.sender){
                owner = true;
            }
        }
        require(owner == true);
        _;
    }
    //Should initialize the owners list and the limit 
    constructor(address[] memory _owners, uint _limit) {
        owners = _owners;
        limit = _limit;
    }
    
    //Empty function
    function deposit() public payable {}
    
    //Create an instance of the Transfer struct and add it to the transferRequests array
    function createTransfer(uint _amount, address payable _receiver) public onlyOwners {
        emit TransferRequestCreated(transferRequests.length, _amount, msg.sender, _receiver);
        transferRequests.push(
            Transfer(_amount, _receiver, 0, false, transferRequests.length)
        );
        
    }
    
    //Set your approval for one of the transfer requests.
    //Need to update the Transfer object.
    //Need to update the mapping to record the approval for the msg.sender.
    //When the amount of approvals for a transfer has reached the limit, this function should send the transfer to the recipient.
    //An owner should not be able to vote twice.
    //An owner should not be able to vote on a tranfer request that has already been sent.
    function approve(uint _id) public onlyOwners {
        require(approvals[msg.sender][_id] == false);
        require(transferRequests[_id].hasBeenSent == false);
        
        approvals[msg.sender][_id] = true;
        transferRequests[_id].approvals++;
        
        emit ApprovalReceived(_id, transferRequests[_id].approvals, msg.sender);
        
        if(transferRequests[_id].approvals >= limit){
            transferRequests[_id].hasBeenSent = true;
            transferRequests[_id].receiver.transfer(transferRequests[_id].amount);
            emit TransferApproved(_id);
        }
    }
    
    //Should return all transfer requests
    function getTransferRequests() public view returns (Transfer[] memory){
        return transferRequests;
    }
    
    
}

this is the error message:

3_multisigWallet_migration.js

@alejandravisa yeah i know what the issue. is unlike the simple helloworld contract, the multisig contract has a constructor. this means that on the creation of the contract it takes in external arguments in order to initialise some of the global variables in the contract.

so thats whats causing that error you see saying invalid number of parameters for "undefined" got 0 expected two. so you have 2 arguments in your constructor that your not passing into your contract on creation.

truffle works a lot differently than remix. remix does everything under the hood for the user in terms of deployment and migration etc. however in truffle it smuch more low level and you have to configure everything yourself, from the migration files, to the networks and other configuration parameters in truffle.config.js. so in order to pass in arguments for use in the constructor you need to do this in your wallet Migration file. so based on your contract above i can see that you need an array of addresses for the owners and an unsigned interger for the limit.
so your current migrations file probably looks like this

const Wallet = artifacts.require("Wallet");

module.exports = (deployer) => {
  deployer.deploy(Wallet, _owners, _limit)
}

however the error is throing at this line

 deployer.deploy(Wallet, _owners, _limit)

this is where you need to add your constructor args, namely the array of owners and the limit. so in your wallet migrations file make these changes

const Wallet = artifacts.require("Wallet");

//we can add extra params such as the accounts
module.exports = (deployer, network, accounts) => {
  //accounts is an array of 9 accounts these are the accounts yu
  //see when you frst open truffle devlop. so to create our array
  ///we can index the accounts array like so
  const _owners = [accounts[0], accounts[1], accounts[2]]
  const _limit = 2
  

   //then to deploy you pass in the name of the contract you
   //want to deploy as usual and then your constructor
   //arguments as extra parameters
  deployer.deploy(Wallet, _owners, _limit)
}

so this will now work. read the comments i put into the code for extra info. and let me know if you have any further issues

when does this error come. is it when you try to npm install truffle or when you try to run truffle init or when you try to do a command like truffl ecompile or truffle migrate??

#524

This error first came when I did truffle init (the truffle compile or truffle migrate i don’t know), but after I reinstalled truffle i saw this in the node.js screen right after the install.

This doesn’t look right.

#529

I see truffle has a VS code extension now. I haven’t used it but was curious if anyone else has? Is it recommended to be using that instead when creating projects on our own?

#530

Hello, I am trying to install truffle but am running into some problems. The first thing I did was download and install node.js 16.15.1, and then went to my computer`s command prompt and attempted to install truffle, which didn’t work so I uninstalled and tried to reinstall with --force. Do I need to do anything else first, any help would be appreciated.
Thanks

Hey, I was having the same problem yesterday. I think I fixed the location problem by updating my npm with the following steps.
