Please take a look into this post, which explain how to send the proper constructor parameters from the migration file to deploy the contract properly:

Hi all,

I tried to interact with the multisig wallet contract using the Truffle console but I came across the following errors shown in the screenshots:

truffle develop error 1

truffle develop error 2

What needs to be done first in order to interact with the multisig wallet contract using the Truffle console?

The ā€œvulnerabilitiesā€ warning message is just that, a warning message, you could either try to solve them (by running npm audit fix, which i do not advice for your case) or just ignore them (also the ā€œWARNā€, they are warning messages about an error in the module that you are downloading, but will not affect the procedure of it).

In the video when he says you can run the truffle download in your command prompt or terminal does he mean
the nodejs?

#390 
Just to continue the conversation of truffle  I downloaded the node js version 14.17.6 and then i went to truffle and pasted the installation code 
npm install -g truffle into the node js
and things didn't work. look forward to your response on both matters

type or paste code here

Hey guys,
I had some problem installing truffle at first, then I found this youtube video: https://www.youtube.com/watch?v=nPLx3rSZPXI

Basically you run this command ā€œsudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}ā€

This seems to have solved my problems :slight_smile:

#398

Using the wallet project, I have a function to find the balance of an address in the wallet contract, and one to find the balance of the contract itself, but Iā€™m looking for the Remix equivalent finding these balances:

How do you check the balance of an address when testing with Truffle? Do you need to write a function in the contract to ā€œgetBalanceā€ of an account outside the wallet?

#399

The command you are using is incorrect, it should be npm install -g truffle

#400

In the truffle console, you can use:

let balance = await web3.eth.getBalance(accounts[0])

then calling the balance variable will return the balance of that address, keep in mind that accounts its an array of accounts with funds created by truffle when you run its local node (truffle develop).
