@Confucian-e Can you please provide more details on the issue? A repo to reproduce would be ideal.

[Confucian-e]

Well my hardhat.config.ts file is:

import "@matterlabs/hardhat-zksync-deploy";
import "@matterlabs/hardhat-zksync-solc";
import "@nomicfoundation/hardhat-toolbox";
import { HardhatUserConfig } from "hardhat/config";

const config: HardhatUserConfig = {
  networks: {
    hardhat: {
      zksync: false,
    },
    zkSyncTestnet: {
      url: "https://sepolia.era.zksync.dev",
      ethNetwork: "sepolia", // or a Sepolia RPC endpoint from Infura/Alchemy/Chainstack etc.
      zksync: true,
    },
  },
  zksolc: {
    version: "latest",
    settings: {},
  },
  solidity: {
    version: "0.8.19",
    settings: {
      optimizer: {
        enabled: true,
        runs: 200,
      }
    }
  },
};

export default config;

Well I just tried your cli, but it shows same error
I followed tutorial here https://docs.zksync.io/build/tooling/hardhat/getting-started.html#project-setup

First I run

pnpm dlx zksync-cli create demo --template hardhat_solidity

Then run

pnpm compile

Then it shows

> hardhat compile

Getting the same issue with v0.8.24

[boyuanx]

zksolc 1.4.0 fixed this issue.

[davosloper]

I am using 1.5.1 (also tried 1.4.0) zksolc and I am still getting EPIPE and sometimes EOF error when I compile. I have updated all packages and node version. Any idea why ?

[bxpana]

Do you have a repo link you can share? Any luck when trying with 1.5.0? or 1.4.1?

[davosloper]

I don't have repository link for this. I just followed the migration part in the docs and tried with 1.3.22, 1.4.0, 1.5.1. Nothing works for me.

[bxpana]

Which docs are you using and without a minimal reproducible code it's hard to replicate to see what's going on. Is this on a local network or Sepolia?

[davosloper]

I followed here: https://docs.zksync.io/build/tooling/hardhat/migrating-to-zksync

Also tried on MacOS 12 (Virtual Machine) and got the following error:

@davosloper Let's open up another discussion around this so we can get as much information about your project as we can. Like I said before it's hard to replicate without any code or a repo
