Vercel部署引发“错误:找不到模块'@next/env'”

Question

我已经试着调试这个错误很久了.Vercel截图我的根目录中有一个.env文件。我对web部署完全陌生，所以我也不太清楚应该在.env文件中放什么。Vercel的错误消息指向/vercel/path0/node_modules/next-sitemap/bin/next-sitemap的目录甚至不是这个项目根目录中的目录。

编辑:这是项目的文件结构。文件结构

EDIT2: package.json文件

Answer 1

您的项目没有package-lock.json文件。这很可能导致error。

1. 从根目录项目目录中删除node_modules目录。下面是一个项目应该是什么样子的例子。

​

​

1. 再次运行npm install。
2. 现在，您应该将package-lock.json文件放在根目录中。
3. 尝试deploy你的应用程序，没有任何问题。
