使用松露部署错误-契约:无法读取未定义的属性“应用”

Question

我使用truffle-contract包来部署使用truffle compile编译的契约

deploy.js

const Web3 = require('web3');
var provider = new Web3.providers.HttpProvider("http://localhost:8545");

const contract = require('truffle-contract');
var FooArtifacts = require("./build/contracts/Foo.json");
var Foo = contract(FooArtifacts);
Foo.setProvider(provider);  

var myContractAddress = "0x6139e1b82ffbdbeafbb403a77a04e8374d2521b1";
Foo.new(myContractAddress);

运行node deploy.js会出现错误

无法读取未定义的属性“应用”

使用truffle-contract 3.0.5，web3 1.0.0-beta.34按packages.json。

这里出了什么问题？

Foo.json伪影

Foo.sol

pragma solidity ^0.4.18;

import './MyContract.sol';

contract Foo {
    uint256 public x;
    MyContract myContract;
    address myContractAddress;

    constructor(address _myContractAddress) public {
        myContractAddress = _myContractAddress;
    }

    function baz() public {
        myContract = MyContract(myContractAddress);
        x = myContract.baz();
    }
}

这是web3 1.0版。

解决办法：

if (typeof contract.currentProvider.sendAsync !== "function") {
  contract.currentProvider.sendAsync = function() {
    return contract.currentProvider.send.apply(
      contract.currentProvider,
          arguments
    );
  };
}
