Ganache 安装

一. 下载Ganache

Ganache下载链接

根据系统选择对应安装文件

或者brew安装

brew install --cask ganache

二.打开app

点击quickstart

点击save按钮，保存workspace，此时已启动对应端口为7545

三.打开truffle项目，设置配置文件

我已初始化好truffle项目，可以看上篇文章truffle示例

module.exports = {
  networks: {
    development: {
      host: "127.0.0.1",
      port: 7545,
      network_id: "*"
    }
  }
};

部署合约项目
