WeBASE-IDE，ChainIDE 开发建链工具 提供一键搭链脚本工具 合约部署与测试 工具 基于Java SDK的console, 交互式控制台基于Web3SDK的 console SDK语言 Java、nodejs、go、python 快速开发组件 提供Spring-boot-starter 压测工具 SDK内嵌压测工具，支持Caliper 运维支持 运维建链工具 提供企业级联盟链部署工具 可视化数据展现 和良好的交互体验，用户可以通过控制台查询区块链状态、读取和修改配 置、管理区块链节点、部署并调用合约。控制台给用户管理、开发、运维区 块链带来了巨大的便利，降低了操作繁琐性和使用门槛。 相比于传统的nodejs等脚本工具，控制台安装简单、使用体验更好。详细请查 看 基于Java SDK的控制台使用手册 和 基于Web3SDK的控制台使用手册。 虚拟机 2.0版本引入了最新的以太坊虚拟机版本，支持Solidity >= 10.14； 部署Caliper的计算机需要安装有以下软件：python 2.7、make、g++、gcc 及git。 第二步. NodeJS 版本要求： NodeJS 8 (LTS), 9, 或 10 (LTS)，Caliper尚未在更高的NodeJS版本中进行 过验证。 安装指南： 建议使用nvm(Node Version Manager)安装，nvm的安装方式如下： # 安装nvm
