反应-为什么 heroku 无法识别我的"models"文件夹？

Question

我想将我的应用程序部署到heroku，但一如既往地会出现错误。这次我不知道问题出在哪里。我希望你们中的一些人能帮助我。它找不到像我的模型/用户文件这样的文件，但我就是不知道为什么。

这是我的heroku日志--尾日志：

我的文件结构(如果有帮助的话(：服务器文件夹、客户端文件夹(里面有package.json(、服务器的package.jsn文件。

Answer 1

查看文件夹结构以及用户模型的代码可能会有所帮助，以帮助解决问题。至于在没有看到这些细节的情况下更明显的潜在问题，我会检查以确保您导出了您的用户模型，并仔细检查到您的路线的路径。对我来说，它看起来要么是/models/User的文件不是相对路径所期望的位置，或者该文件可能由于导出而不可见。
