我尝试在 next.js 中获得生产版本以在我的服务器上运行它，但是当我尝试时我无法构建 next.js 生产版本

npm 运行构建

有谁知道如何让 next.js 中的 prod 构建正常工作我做了 next.js 文档中的所有内容，但总是在下面出现此错误。如果我做一个开发构建它工作得很好但是尝试生产构建会导致错误。

我也做了很多次next build并重新安装了所有仍然存在此错误的 node_modules 包。

它总是在终端显示我

我尝试获取一些子页面，例如

• example.com/tests/project1
• example.com/tests/project2

在 nextjs https://nextjs.org/

我能够创建类似的页面

• example.com/page1
• example.com/page2

通过把这样的页面

page1.js

在页面“文件夹”中，但如何创建子页面，例如

• example.com/tests/page1
• example.com/tests/page2

我尝试的是在 Pages 文件夹中创建子文件夹，但这不起作用并输出错误。

非常感谢帮助

我有一个问题，我想创建一个 CSS 循环渐变动画，但是当我这样做时，动画是非常静态的，它不能流畅地动画 下面是我目前正在处理的示例。希望你能帮助我。

}

  }
  50% {
    background: linear-gradient(rgba(173, 136, 255, 0.44), rgb(135, 255, 0))
