返回值无效，是不是 运行 没油了？ web3 1.5.0 和 sol-0.5.15
Returned values aren't valid, did it run Out of Gas? web3 1.5.0 and sol-0.5.15
我是区块链和以太坊领域的新手。我一直在尝试使用 truffle 和 ganache 创建一个简单的测试网络，我在 truffle 中创建了一个新的工作场所，并尝试构建一个快速反应的前端应用程序以使用 Web3 连接到以太坊。
一切正常。我确实安装了 MetaMask 并为 port:7545 创建了一个新网络，ganache 发生的每一次变化都会影响 MetaMask。
这是web3的代码。
const web3 = new Web3("http://127.0.0.1:7545")
const accounts = await web3.eth.getAccounts()
setaccount(accounts)
const todoList = new web3.eth.Contract(TodoList.abi, ADRESS);
console.log('here the todo contract');
console.log(todoList);
setTodoList(todoList)
const taskCount = await todoList.methods.taskCount().call()
联系人显示正常，帐号也正常。
但是当我尝试调用该函数时，它向我显示了这个让我感到困惑的错误。
Uncaught (in promise) Error: Returned values aren't valid, did it run Out of Gas? You might also see this error if you are not using the correct ABI for the contract you are retrieving data from, requesting data from a block number that does not exist, or querying a node that is not fully synced.

问题 : 我使用了节点的地址，而不是应用 truffle migrate --reset all .
后的合约地址
所以我使用松露和甘纳许尝试了相同的代码，它对我有用。唯一的区别是我在端口 8545 上使用 运行 ganache 并将元掩码连接到 url 中的该端口。我相信您在这里提供的值有些不正确 const todoList = new web3.eth.Contract(TodoList.abi, ADRESS);
确保你的合约的 abi 和 address 是正确的。阅读有关使用正确值实例化合约对象的详细信息 here
这是我阅读 JSON 文件的方式：
const TodoList = JSON.parse(fs.readFileSync('./build/contracts/TodoList.json', 'utf8'));.
我只是像你的代码一样从中提取abi。对于合约地址部分，我在 运行 truffle migrate --reset all.
之后从输出控制台手动获取地址

// Truffle DB is currently disabled by default; to enable it, change enabled: false to enabled: true
//
// Note: if you migrated your contracts prior to enabling this field in your Truffle project and want
// those previously migrated contracts available in the .db directory, you will need to run the following:
// $ truffle migrate --reset --compile-all
db: {
enabled: false
}
};
对我来说，我不得不重新运行 truffle migrate --reset 并且成功了。
