無法解構“未定義”或“空”的屬性“介面”。如何解決這個問題？

const assert = require('assert');
const ganache = require('ganache-cli');
const Web3 = require('web3');

const provider = ganache.provider();
const web3 = new Web3(provider);

const { interface, bytecode } = require('../compile');

let accounts;
let inbox;

beforeEach(async () => {
 // Get a list of all accounts
 accounts = await web3.eth.getAccounts();
 // Use one of those accounts to deploy the contract
 inbox = await new web3.eth.Contract(JSON.parse(interface))
   .deploy({ data: bytecode, arguments: ['Hi there!'] })
   .send({ from: accounts[0], gas: '1000000' });


 inbox.setProvider(provider);
});

describe('inbox', () => {
 it('deploys a contract', () => {
   assert.ok(inbox.options.address);
 });
 it('has a default message', async () => {
   const message = await inbox.methods.message().call();
   assert.equal(message, 'Hi there!');
 });
});

錯誤在於require('../compile')肯定，因為它必須返回空值。

嘗試參考下面的程式碼來編譯solidity程式碼。檢查您的 compile.js 文件是否以類似的方式工作。

// Compile the source code
const input = fs.readFileSync('Coin.sol');

const output = solc.compile(input.toString(), 1);

const bytecode = output.contracts[':Coin'].bytecode;

const abi = JSON.parse(output.contracts[':Coin'].interface);

確保你 const abi = JSON.parse(output.contracts[':Coin'].bytecode); 在“compile.js”中得到了“Coin.sol”的“C”，因為這就是它的儲存方式
