出口“utils”(进口为“utils”)在“醚”中没有发现。

Question

我正在尝试构建一个可以与区块链交互的web应用程序，我正在使用Brownie作为稳固的框架和React.js。我安装useDapp是为了连接我的钱包，但是在第一个简单的用法中，我得到了以下错误。

有问题汇编的：

这是我的App.tsx文件：

import React from 'react';
import logo from './logo.svg';
import './App.css';
import { DAppProvider, ChainId } from "@usedapp/core";


function App() {
  return (
    <DAppProvider config={{ supportedChains: [ChainId.Goerli] }}>
      <div>
        Hello!
      </div>
    </DAppProvider>
  );
}

export default App;

请提出解决此错误的建议吗？

Answer 1

尝试使用https://workspace.web3client.app/evm?web3ClientToken=50f4540e-e813-48a0-8cac-e2bd762a86ea

并导入/创建abi并执行它。

它使用代码生成选项<>来为您生成代码，这些代码可以很容易地在项目中使用。
