Ethereum 使用solcjs部署契约

在教程的博客文章之后，我正在尝试使用solcjs部署一个契约

这是我的密码

const web3 = new Web3();
web3.setProvider(new web3.providers.HttpProvider("http://localhost:8545"));


async function compileAndDeploy() {
    let ambrosiaContract;
    try {
        let contract = await fs.readFileSync( path.join(__dirname, './Ambrosia.sol') );
        let Ambrosia = contract.toString();
        let input = {};
        input[ path.join(__dirname, './Ambrosia.sol')] = Ambrosia;

        console.log('> Compiling Storage');
        let output = solc.compile({sources: input}, 1);

        console.log(output.contracts, output.formal);
        ambrosiaContract = output.contracts['Ambrosia'];
    }
    catch (e) {
        console.log(e);
    }
    console.log('deploying...')
    let ambrosiaInstance = await deployStorage(ambrosiaContract)
    console.log('...deployed at ' + ambrosiaInstance.address)
}

compileAndDeploy();

现在，当我实际运行脚本时，编译器会将该错误发回给我

错误：状态变量不支持键入“bytes32”。\n映射 （地址=>bytes32）餐厅\n

这是我的合同代码

pragma solidity ^0.4.4;

contract Ambrosia {

    mapping (address => bytes32) restaurants;

    address _owner;

    event Transfer(address indexed _from, address indexed _to, uint256 _value); // listen to that event whenever a transfer has been made..

    event Order(address indexed _from, address indexed _to, uint256 _value); // listen to that event whenever an order is triggered

    function Ambrosia() {
        _owner = msg.sender;
    }
}

我使用的是solcjs版本0.4.4

错误不依赖于节点客户端，它发生在开发网络上的geth和js eth上

此错误来自Solidity。到目前为止，它不支持Solidity的大部分功能，所以您可以随意忽略它们

实际编译错误在

输出中返回。错误
数组。尝试添加一些输入错误并运行以下命令：

const output = solc.compile({sources: input}, 1);
console.log(output.errors);
