Truffle搭建环境migrate步骤错误解决方案

1.truffle migrate失败

报错信息为：

2_deploy_contracts.js
=====================

C:\Users\asus\AppData\Roaming\npm\node_modules\truffle\build\cli.bundled.js:260211
  throw new Error("Could not find artifacts for " + import_path + " from any sources");
        ^
C:\Users\asus\AppData\Roaming\npm\node_modules\truffle\build\cli.bundled.js:260211
  throw new Error("Could not find artifacts for " + import_path + " from any sources");
  ^

报错信息的意思是找不到该合约的位置，所以无法执行deploy操作

2.解决方案

我查阅过很多个博客都没有好的解决方案，于是在自己探索的情况下找到解决方案。

在2_deploy_contracts.js文件中，将require里面的参数改成你的合约名字,

而不是sol文件名字，即不必sol后缀，这一点比较坑！！！

这里可以看到编译后的合约名字。

//var ConvertLib = artifacts.require('./ConvertLib.sol')
var Test = artifacts.require('./Test')
//var Test = artifacts.require('.Test.sol')

module.exports = function (deployer) {
  //deployer.deploy(ConvertLib)
  //deployer.link(ConvertLib, MetaCoin)
  deployer.deploy(Test)
}

3. migrate显示未打开网络

4.解决方案

修改文件目录下的truffle-config.js配置为以下

// Allows us to use ES6 in our migrations and tests.
require('babel-register')
module.exports = {
networks: {
        development: {
            host: "localhost",
            port: 8545,
            network_id: "*" // 匹配任何network id
         }
    }
};
