Node.js Express服务器在本地工作，但在heroku上崩溃

我的Node+Express服务器正在本地工作，但在Heroku上不工作

同样值得一提的是，我正在使用heroku postgres运行这些命令

heroku run knex migrate:latest-a myAppName

heroku run knex seed:最新-myAppName

命令运行成功，我可以在Heroku上看到种子数据库

有什么问题吗？

现在，当我尝试访问服务器时，由于找不到某些模块，它无法正常工作，但在我这方面，它同样可以正常工作

我也从我的开发分支部署，还没有合并到master，但这应该不是问题

[已解决]

似乎GitHub不会跟踪文件夹大小写敏感度的变化，所以即使我重命名文件夹，它也不会工作。我将所有内容复制到一个新的repo中，并成功部署了它。

尝试更改

const{validateUserID}=require（“../../Users/middleware/validateUserID”）

到

const{validateUserID}=require（“../../users/middleware/validateUserID”）

使用小写用户
linux是区分大小写的，如果您有mac，它可能会在服务器上出现问题，但在您的机器上不会出现问题。
您的路由路径不正确，节点无法在Heroku文件系统中找到这些路径

使用类似“./”的命令删除当前文件，以便更新为：

const authRoutes = require("./../Authentication/Routes/AuthRoutes");

不幸的是，它没有起作用，我真的不知道。我明天会尝试将我的整个结构更改为camelcase。我刚刚注释掉了导入，并将其从路由中删除，问题仍然存在于其他控制器中……就是这样！git没有跟踪这些变化，所以我不得不将所有内容复制到新的回购协议中，现在我要看看如何强制git改变它，只需添加-require是区分大小写的，缓存仍然会将它们视为不同的模块，并将多次重新加载文件。好的，我只是通过以下方式在我的主repo上实现了它，我尝试了与关于区分大小写路径的答案相结合，但没有任何效果另外，为了安全起见，请开始这样做，谢谢SamuelCol，还有-始终命名文件，并要求在所有地方都使用小写<如果您需要（'mymodule'），则代码>require
区分大小写，require（'mymodule'）节点将它们视为两个独立的组件实例
const authRoutes = require("./../Authentication/Routes/AuthRoutes");
