Express服务器在本地工作，但在heroku上崩溃

时间：2019-11-20 20:14:06

标签： node.js postgresql express heroku

我的Node + Express服务器在本地运行，但不在Heroku上运行。

还值得一提的是，我正在使用heroku-postgres并运行以下命令

heroku run knex migrate:latest -a myAppName heroku run knex seed:latest -a myAppName

命令成功运行，我可以在Heroku上看到种子数据库。

出了什么问题？

现在，当我尝试访问服务器时，由于无法找到某些模块，它将无法工作，但再次在我端正常工作

我也在从我的开发分支进行部署，还没有合并到master上，但这不应该是问题。

[已解决]

似乎GitHub没有跟踪文件夹区分大小写的更改，因此即使我重命名了文件夹，它也无法正常工作。我将所有内容复制到新的存储库中，并成功部署。

2 个答案:

答案 0 :(得分：1)

尝试更改

const { validateUserID } = require("../../Users/Middlewares/validateUserID");

到

const { validateUserID } = require("../../users/Middlewares/validateUserID");

使用小写字母的用户 linux区分大小写，如果有Mac，它可能会在服务器上出现问题，但在计算机上不会出现问题。

答案 1 :(得分：1)

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“ ./”之类的格式处理当前文件，以便更新至：

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