Question

尝试按照迎宾教程，虽然我已经回避了一些问题（无法在本地安装solC），但这个让我陷入困境。

我已经在网上编制了可靠性https://ethereum.github.io/browser-solidity/#version=soljson-latest.js

结果是右边两个不同的部分，一个用于'greeter'，一个用于'mortal'。

我在本地启动geth控制台并使用“personal.unlockAccount”解锁我的帐户。在粘贴了欢迎合同的“Web3部署”部分的文本后，我得到了回复 null [object Object] 从geth控制台和控制台冻结，不会出现另一个提示。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,
{

gas: 3000000
}, function(e, contract){
console.log(e, contract);
if (typeof contract.address != 'undefined') {
     console.log('Contract mined! address: ' + contract.address + ' transactionHash: ' + contract.transactionHash);
}
})

任何人都有线索，因为我肯定不会

Answer 1

null [object Object]一定不会出现任何问题。

开始挖掘，miner.start（），并等待合同挖掘地址的回归，获取地址取决于CPU的速度。等等。

尝试使用比greeter更简单的示例查看此链接，可能有用
