# 错误：MongoDB 在 Render.com 网站部署应用程序

Question

我有这个错误：

`Error: Cannot find module '/opt/render/project/src/server/node_modules/@mongodb-js/saslprep/dist/node.js'
at createEsmNotFoundErr (node:internal/modules/cjs/loader:1181:15)

进入render.com的实时看板报告

这就是我想做的：

• 1/ 在 render.com 部署与在线餐厅相关的后端 Node 应用程序
• 2/ 在 vercel 中部署我的反应应用程序

但是我在尝试 1/（第一步）时遇到了问题。上面给出的问题

我尝试过：

• 删除

  node_modules

  包并重新安装所有依赖项
• 删除

  dist

  文件夹并使用

  package.json

  脚本中的 npm run build
命令集重建它
• 根据这些更改
更新github上的存储库

但似乎没有什么能解决问题

我不知道我做错了什么。这是我的:

package.json 文件

请任何帮助如何解决这个问题将帮助我最终部署应用程序。 谢谢您的宝贵时间。

Answer 1

在github中，我不小心推送了node_modules文件夹。我遇到了同样的问题。一旦我删除了node_modules文件夹，那么部署就成功了。
