node.js - 每当我尝试使用 Next.js 运行 'npm run dev' 时都找不到错误模块

Question

每当我跑 npm run dev我收到这个错误。
我试图删除 node_modules并使用 npm install 重新安装它但这没有用。然后我试图删除两个 node_modules和 package-lock.json并重新安装它们，这不起作用。我什至尝试将 Node 升级到最新版本，但我仍然遇到这个问题。
我很感激我得到的任何帮助。先感谢您。

停止你的开发服务器 (ctrl+c)

删除 .next项目根文件夹中的文件夹。

删除 node_modules文件夹和 package-lock.json文件也是。

运行 npm cache clean --force

运行 npm install

运行 npm run dev

如果上述方法不起作用，请打开文件资源管理器并查看指定的文件是否存在于指定的路径中: C:\Users\jaydev\Desktop\ecommerce\fashionsite\node_modules\postcss\lib\parser.js如果存在，请尝试将您的项目文件夹移动到 desktop 以外的路径。由于 Windows 权限问题，如果问题已解决，请告诉我。
