本文介绍的是 我 最近发现的一个 CLI 交互式开源许可证生成器以及查看器，它是使用 JavaScript 编写的，虽然最后更新还在 2017 年（现在已经是 2022 年了 😄 ），但是它仍然工作得很好，可以非常方便的生成我们需要的开源许可证 LICENSE 文件
安装
安装很简单，不管你的操作系统是什么，只要安装了 Node.js、NPM 或者 Yarn
# 使用 NPM 安装
npm install -g lice
# 使用 Yarn 安装
yarn global add lice
使用
交互式
交互式的开源许可证生成器/查看器是它的灵魂，在你想要生成 LICENSE 许可证文件的路径打开终端，输入 lice 即可进入交互式 CLI
第一个是开源许可证生成器，第二个是开源许可证查看器，选择了生成器以后，交互式 CLI 会继续询问你选择什么开源许可证
选择好我们想要的开源许可证并回车后，接下来会询问你版权持有人
最后输入年份即可
这样我们就生成了一个合适的开源许可证 LICENSE 文件
比如，截图演示的 MIT 许可证内容如下
