在使用Truffle和Ganache开发以太坊智能合约时遇到部署异常'invalid opcode'。问题源于Truffle内置的Solidity编译器可能产生的opcode不被EVM接受。通过自定义Solidity编译器，注释掉truffle-config.js中的相关配置，并利用外部编译器进行编译，解决了此问题。

异常重现

最近在使用truffle框架与Ganache开发以太坊合约的时候，采用默认配置的时候（仅修改端口为7545），部署时会出现invalid opcode异常如下图：

项目初始化

通过命令truffle unbox webpack进行项目初始化
项目目录如下：

配置文件truffle-config.js详情

/**
 * Use this file to configure your truffle project. It's seeded with some
 * common settings for different networks and features like migrations,
 * compilation and testing. Uncomment the ones you need or modify
 * them to suit your project as necessary.
 *
 * More information about configuration can be found at:
 *
 * truffleframework.com/docs/advanced/configuration
 *
 * To deploy via Infura you'll need a wallet provider (like truffle-hdwallet-provider)
 * to sign your transactions before they're sent to a remote public node. Infura accounts
 * are available for free at: infura.io/register.
 *
 * You'll also need a mnemonic - the twelve word phrase the wallet uses to generate
 * public/private key pairs. If you're publishing your code to GitHub make sure you load this
 * phrase from a file you've .gitignored so it doesn't accidentally become public.
