ethereum - 错误 : insufficient funds for gas * price + value

Question

我正在通过 first tutorial in the Ethereum website .

我已经使用 Remix 编译了合约代码并创建了以下脚本。为简洁起见，我删除了二进制字符串:

var _greeting = 'Hello World!';
var browser_untitled_sol_greeterContract = web3.eth.contract([{"constant":false,"inputs":[],"name":"kill","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"greet","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"inputs":[{"name":"_greeting","type":"string"}],"payable":false,"stateMutability":"nonpayable","type":"constructor"}]);
var browser_untitled_sol_greeter = browser_untitled_sol_greeterContract.new(
 _greeting,
 {
   from: web3.eth.accounts[0], 
   data: 'BINARY_STRING', 
   gas: '4700000'
 }, function (e, contract){
   console.log(e, contract);
   if (typeof contract.address !== 'undefined') {
     console.log('Contract mined! address: ' + contract.address + ' transactionHash: ' + contract.transactionHash);
   }
})

var browser_untitled_sol_mortalContract = web3.eth.contract([{"constant":false,"inputs":[],"name":"kill","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"inputs":[],"payable":false,"stateMutability":"nonpayable","type":"constructor"}]);
var browser_untitled_sol_mortal = browser_untitled_sol_mortalContract.new(
   {
     from: web3.eth.accounts[0], 
     data: 'BINARY_STRING', 
     gas: '4700000'
   }, function (e, contract){
     console.log(e, contract);
     if (typeof contract.address !== 'undefined') {
       console.log('Contract mined! address: ' + contract.address + ' transactionHash: ' + contract.transactionHash);
   }
})

加载此脚本时，我得到:
Error: insufficient funds for gas * price + value .

打电话时 eth.getBalance(eth.accounts[0])我得到: 399577000000000
我不知道我的余额中应该有多少 eth 才能运行这个脚本，或者我是否需要将 eth 转换为 gas。

Answer 1

您不会将以太“转换”为气体。您使用以太币支付所使用的天然气费用。

无论如何，您收到的错误消息似乎是正确的。你的余额很低。 eth.getBalance()返回Wei中的余额。你的余额只有 ~0.0004 ether，这是相当低的(你可以使用 https://etherconverter.online/ 转换为 ether 或使用 web3.fromWei(val, 'ether') 在代码中转换)。

您需要的以太币数量取决于合约中执行的操作，以及您愿意为所使用的 gas 支付多少(您可以覆盖交易对象中的默认值 gasPrice)。尝试挖掘或将更多以太币转移到您的帐户中。
