跟宁哥学区块链开发（3）：Web3.js详解

     本课程是《跟宁哥学区块链开发》的第3套课程，本系列课程包含了区块链和以太坊基础知识、Solidity语言详解、Web3.js详解、Truffle以太坊开发框架、项目实战（包括支持以太坊的微信小程序版记事本、用Electron实现的DApp云笔记、用Electron实现的DApp MySQL数据库管理系统【支持将数据保存到以太坊中】）。

& nbsp; & nbsp; & nbsp; this course is the third set of courses in The Development of Block Chains with Ningko School, which includes block chains and basic knowledge of the community, detailed interpretation in the language of Solity, Web3.js elaboration, framework for the development of the Truffle community, project reality (including support for the micro-letter program in Etai, Dapp cloud notes in Electron, Dapp MySQL database management system in Electron [supports the preservation of data in Etheria]).

注意：如果在Windows下使用solc命令编译sol文件时，如果solc已经安装成功，还是提示solc命令没有找到，请在后面加cmd扩展名，也就是说要执行solc.cmd才可以。

Note: If solc command is used under Windows to compile sol files, if solc has been installed or the hint solc command has not been found, add cmd extension at the back, i.e. only solc.cmd can be executed.
