I’m following through the video on creating a ERC20 token exercise in the Ethereum smart contract 201 course. I’ve followed the steps with Fhilip in installing openzepplin using npm, and initialing truffle. However, when I tried to import the ERC2.sol library and compile the code, I run into the following problem(s). Anyone have an idea what’s going on?
note: I’ve included the pragma solidity version into truffle-config.js file as well, and it doesn’t seems to solve the problem
