松露-已部署合同上的合同错误

Question

使用gnosis multisig，使用松露-契约与已经部署的MultiSigWallet交互使用松露迁移。

我试图运行的文件的内容：

var contract = require('truffle-contract');

var fs = require('fs');
var Web3 = require('web3');
var web3 = new Web3('http://localhost:9545');
var provider = new Web3.providers.HttpProvider('http://localhost:9545');

var fileData = fs.readFileSync('./build/contracts/MultiSigWallet.json');
var jsonData = JSON.parse(fileData.toString());

var myContract = contract(jsonData);
myContract.setProvider(provider);

myContract.deployed().then(function(instance) {
        var deployed = instance;
        return deployed.address;
})
.then(function(result) {
        console.log(result);
})
.catch(err => { 
        console.log(err);  
});

当我使用节点运行时，获取错误：

TypeError: Cannot read property 'apply' of undefined

    at RequestManager.sendAsync (/home/delphi/MultiSigWallet/node_modules/truffle-contract/node_modules/web3/lib/web3/requestmanager.js:80:19)

    at startup (bootstrap_node.js:204:16)
    at bootstrap_node.js:625:3

错误中提到的未定义的是myContract.deployed()。但我不明白为什么会这样。简单的控制台输出显示，myContract不是未定义的。有人能帮我弄清楚是怎么回事吗？

Answer 1

import contract from 'truffle-contract'

但是，节点此文件将报告错误“SyntaxError:意外标识符”
