我想在NextJS中创建我的第一个项目。我遵循以下步骤：
npx创建下一个应用程序@最新
npm运行开发
但我得到了以下错误：
grafeno30@linuxHome:~/src/NextJS/file-based-routing/my-app$ npm run dev
> my-app@0.1.0 dev
> next dev
/home/grafeno30/src/NextJS/file-based-routing/my-app/node_modules/next/dist/cli/next-dev.js:315

您正在运行一个旧版本的Node.js (v12.22.9)，它不支持在next包中使用的??操作符。错误消息表明，next包至少需要运行Node.js 14.6.0。
要解决此问题，您需要按照Node.js上的说明，将您的版本的Node.js网站更新为至少14.6.0。一旦更新了Node.js，就可以尝试再次运行npm来启动开发服务器。
此外，在更新Nodejs之后，您可以尝试删除node_modules目录并再次运行npm，以确保所有必需的包都安装了兼容的版本。
