这是我的truffle.js文件

// Allows us to use ES6 in our migrations and tests.
require('babel-register')

module.exports = {
  networks: {
    ganache: {
      host: 'localhost',
      port: 8545,
      network_id: '*' // Match any network id
      //gas: 470000
    }
  }
}

奶糖版本- 6.4.1

Answer 1

请尝试使用以下代码运行它，用开发替换ganache。

module.exports = {
networks: {
development:{
host:"localhost",
port: 8545,
network_id: "*"
}}};

Answer 2

松露中的默认网络是development。

为了在不同的网络上运行命令，需要在命令truffle migrate --network ganache中指定网络。
