hey, could someone help me? I’m trying to. create test token using truffle and openzeppelin. But I’m. getting error during compiling! but i’m. using default tutorial box. what am I doing wrong?

What's the error

,@openzeppelin/contracts/utils/Address.sol:53:32: ParserError: Expected ',' but got 'payable'
function sendValue(address payable recipient, uint256 amount) internal {
^-----^

i’ve found how to fix it. but why was it happen? when i’m using tutorial from openzeppelin 🙂

default ERC20 contract

Possibly version mismatch

Happens to me a lot when I try to upgrade 0.4 to 0.7

which version should i use?

Well, latest :)

but im using version from openzepellin’s contract 😄

pragma solidity ^0.6.0;

Hmm that's wierd, coz I just compiled the same code and it works properly...

could you tell me your node version and solc version?

I am on remix

got it, thanks

will continue learing 🙂 then resolve this issue somehow 🙂

💪 keep coding

thanks!

it’s correct version.

https://docs.openzeppelin.com/contracts/3.x/erc20

same issue

Is your function of type payable ?

nope

have an empty contract

pragma solidity ^0.6.0;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract GLDToken is ERC20 {
constructor(uint256 initialSupply) public ERC20("Gold", "GLD") {
_mint(msg.sender, initialSupply);
}
}

0.4.24?

it’s my local version. i think during compilint another version is used

but im not sure

added into truffle.json

compilers: {
solc: {
version: "^0.6.0"
}
}

and it works! thanks

Solidity ?

Of course
