智能合约编译时报错

最近学习智能合约的时候总是遇到很多坑，想着好不容易解决了，就记录一下好了，这里是在node下编译我的Voting.sol文件遇到的错误

【智能合约编译时|智能合约编译时 solc.compile() 编译报错】……
var solc = require(‘solc’)
var sourceCode = fs.readFileSync(‘Voting.sol’).toString()
var compiledCode = solc.compile(sourceCode)
……
此时我想查看compiledCode，输入 compiledCode 发现报错：
‘{“errors”:[{“component”:“general”,“formattedMessage”:"* Line 1, Column 2\n Syntax error: value, object or array expected.\n* Line 1, Column 3\n Extra non-whitespace after JSON value.\n",“message”:"* Line 1, Column 2\n Syntax error: value, object or array expected.\n* Line 1, Column 3\n Extra non-whitespace after JSON value.\n",“severity”:“error”,“type”:“JSONError”}]}’
查了很多方法，一个是在readFileSync和solc.compile()中加入参数

var sourceCode = fs.readFileSync('Voting.sol','utf-8').toString() var compiledCode = solc.compile(sourceCode,1)

此时直接弹出ERR_ASSERTION
