以太坊欢迎教程 : contract returns "null [object Object]"

Question

尝试按照 greeter 教程进行操作，虽然我回避了一些问题(无法在本地安装 solC)，但这个问题让我陷入困境。

我在 https://ethereum.github.io/browser-solidity/#version=soljson-latest.js 在线编译了 solidity

结果是右边有两个不同的部分，一个是“greeter”，一个是“mortal”。

我在本地启动 geth 控制台并使用“personal.unlockAccount”解锁我的帐户。粘贴迎宾契约(Contract)“Web3 部署”部分的文本后，我得到了回复
null [对象对象]
从 geth 控制台和控制台卡住并且不显示另一个提示。这是粘贴:

var _greeting = "yellow";
var greeterContract = web3.eth.contract([{"constant":false,"inputs":[],"name":"kill","outputs":[],"type":"function"},{"constant":true,"inputs":[],"name":"greet","outputs":[{"name":"","type":"string"}],"type":"function"},{"inputs":[{"name":"_greeting","type":"string"}],"type":"constructor"}]);
var greeter = greeterContract.new(
_greeting,
{
 from: web3.eth.accounts[0],

}, function(e, contract){
console.log(e, contract);
if (typeof contract.address != 'undefined') {
     console.log('Contract mined! address: ' + contract.address + ' transactionHash: ' + contract.transactionHash);
}
})

任何人都知道，因为我肯定不知道

Answer 1

我猜 null[object Object] 一定不会造成任何问题。

开始挖矿，miner.start()，等待合约挖出的地址返回，获取地址取决于CPU速度。等着吧。

尝试从比 greeter 更简单的例子开始检查此链接，可能会有用
