javascript - Next.js 不加载 jsx

问题描述

我一直在寻找当下的javascript框架Next.js，我想开始实践。问题是：它无论如何都不能在我的电脑上运行。

创建下一个项目的自然形式是使用命令行：

npx create-next-app

或者

yarn create next-app

结果是一个带有文件结构和一些脚本来运行服务器的模板项目。最基本的脚本以开发模式运行服务器：

npm run dev

或者

yarn dev

终端的结果是警告：

$ yarn dev
yarn run v1.22.5
$ next dev

 of the package at C:\Users\maths\Documents\codigos\node\my-app\node_modules\next\node_modules\postcss\package.json.
Update this package.json to use a subpath pattern like "./*".

当我在 localhost:3000 中输入网站时，浏览器上的页面显示：

从浏览器发出 http 请求后，终端显示以下消息：

  ]
}

我尝试了几件事来修复它，从 npx 和 yarn （通过手动安装依赖项）创建没有脚本的下一个项目，更新 node 和 npm 的版本等。似乎程序无法加载 jsx，第一个错误指向第一个 jsx 组件出现在代码中的时刻。消息说 webpack 没有为这个代码配置一个有效的加载器。

环境：

赢得 10
npm v7.3.0
节点 v15.5.0
下一个 v10.0.4
反应 v17.0.1
反应域 v17.0.1
