Hi team,
I’m a begginer in smart contracts programming and I’m having trouble deploying my ERC777 contract following the SimpleERC777 example. Could you please give me some hints ? I’ve been trying for hours but I don’t know if it come from my contract itself, my deployement file, my network (ganache), my config WSL2…
(In my opinion it’s a problem related to test-helpers dependencies access after runing npm. I think the require statement in my deploy file can not be found.)

contract QlayToken is ERC777 {

constructor () public ERC777("QlayToken", "MIM", new address[](0)) {

}
}
My migration
const QlayToken = artifacts.require('QlayToken');
require('@openzeppelin/test-helpers/configure')({ provider: web3.currentProvider, environment: 'truffle' });
const { singletons } = require('@openzeppelin/test-helpers');
module.exports = async function (deployer, network, accounts) {
if (network === 'development') {
// In a test environment an ERC777 token requires deploying an ERC1820 registry
await singletons.ERC1820Registry(accounts[0]);
}
await deployer.deploy(QlayToken);
};
I suspected the issue was node v14.3 but I just used nvm to change to node v14.3 and could migrate ok. I normally use node v10 as the ecosystem has had trouble in the past with the latest versions of node.
Thank you for your reply @abcoathup.
I’ve tried using ganache-cli before but I have an error message (below). That is why I decided to use Ganache GUI.

I’ve tried to check for this file “deployement.js” but I can’t find it…
Also, I’m using Windows terminal to run all my commands.
These are my hypothesis :
1 - TRUFFLE INSTALLING PROBLEM
There is no file deployement.js existing on my WSL -> Maybe a probleme while installing truffle ? (after reinstall it, nothing changed)
2 - WSL PATH
There is a problem related to my path - (I don’t have the linux Icon on my windows file explorer though)
My starting directory from my Windows Terminal (Ubuntu) is //wsl$/Ubuntu/home/hydris
Hi @abcoathup,
I come back because I still haven't found the answer to my problem...
Both my assumptions are wrong. I've reinstalled WSL so it's not that.
I managed to use ganache-cli, but that doesn't solve anything.
If you have any advice... it would help me a lot.
I assume that you used an earlier version of node (than node 14). What was the error that you had when trying to migrate?
Would you mind sharing a repository or your current contract, migrations script and your current versions of node, npm, truffle that you are using. (If you use npx truffle version this will give you these).
I used nvm to change my node version from 14.3 to 10.19 -> The result is : I have less errors but still one.

Also, I’ve tried to use Remix IDE to have an other point of view. I can successfully compile but I still can’t migrate for some reasons. I believe there is a problem in the structure of my token contract (which is the SimpleERC777)
I figured out the solution and I’m a little disappointed ahah.
It’s a bad configuration of my ganache connection… So I modified the truffle-config file to match with ganache…
