Question

我用打字稿创建了一个节点应用程序。当我在本地运行tsc时，一切正常，我可以运行该应用程序。但是当我在heroku上部署时，它给了我编译错误：

      app/api/controllers/ingredient.controller.ts(3,24): error TS2307: Cannot find module '../schemas/ingredient.schema'.
   app/api/controllers/ingredient.controller.ts(23,13): error TS7006: Parameter 'units' implicitly has an 'any' type.
   app/api/controllers/ingredient.controller.ts(30,42): error TS7006: Parameter 'result' implicitly has an 'any' type.
   app/api/controllers/ingredient.controller.ts(37,70): error TS7006: Parameter 'result' implicitly has an 'any' type.
   app/api/controllers/ingredient.controller.ts(44,70): error TS7006: Parameter 'result' implicitly has an 'any' type.

奇怪的是，我确保所有版本都相同：NPM，Node，TSC ...

我有一个TSConfig可以使用。我应该去哪里看看？

版本：

       v13.3.0
       6.13.1

建议

在本地运行tsc并部署构建的.js文件。
不要部署打字稿文件，这将为您的远程代码库添加很多代码。

错误

此错误表示某些ts规则未应用于您的本地ts。
我注意到rootDir是./app，并且您已经包括了/app。也许它正在/app下寻找/app文件夹。以root身份尝试./，看看是否可以解决。顺便说一句，我是OvernightJS的创建者，我强烈建议您在部署之前先转换所有代码。

TSC无法在不同的系统上编译
