Heroku 未检测到 Node.js 应用程序

Question

我在 Visual Studio 中创建了一个小型网站，并使用了 Node.js 和 Express。我可以通过 Visual Studio 和 Heroku 本地网络访问它。但是，当尝试将其推送到 Heroku 时，我收到错误:'heroku/nodejs' buildpack 不支持应用程序

我阅读了Heroku提供的文档，但没有找到任何解决方案。

ERROR: Application not supported by 'heroku/nodejs' buildpack
remote:  !
remote:  !     The 'heroku/nodejs' buildpack is set on this application, but was
remote:  !     unable to detect a Node.js codebase.
remote:  !
remote:  !     A Node.js app on Heroku requires a 'package.json' at the root of
remote:  !     the directory structure.
remote:  !
remote:  !     If you are trying to deploy a Node.js application, ensure that this
remote:  !     file is present at the top level directory. This directory has the
remote:  !     following files:
remote:  !
remote:  !     Portfolio/
remote:  !     Portfolio.sln
remote:  !
remote:  !     If you are trying to deploy an application written in another
remote:  !     language, you need to change the list of buildpacks set on your
remote:  !     Heroku app using the 'heroku buildpacks' command.

Answer 1

此错误输出非常简单 - 确保您的 package.json 位于项目的顶级目录中，然后再次尝试部署。根据您的评论，package.json 似乎位于 {project_root}/Portfolio/package.json 而不是 {project_root}/package.json。
