node.js - 从节点应用程序“未能检测到”构建包构建 Heroku

问题描述

我重新组织了我的应用程序，当我将其重建到我的 heroku 服务器上时，出现以下错误

remote: ! 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.

我知道这个问题可以通过重新排列我的文件夹结构来解决。我不想这样做，因为它按原样组织得很好。我想知道如何在不重组项目的情况下解决问题。

当前文件夹结构

\client\package.json
\client\node_modules
\client\{all other client files}

server\package.json
server\{all other server files}
server\none_modules
\wiki\{all wiki files}
.gitignore

我尝试过的

我已阅读建议将 package.json 放在根目录中的文章。我在那里尝试了一个名为 package.json 的空 json 文件，但它不起作用，因为我猜它实际上正在使用该文件，并且它想读取位于我的 \server 目录中的文件来运行构建脚本。

我想知道我是否可以只调用 heruku 在不同的目录中启动？

尝试 2

我尝试创建一个名为 Procfile 的文件并向其中添加以下内容

web: npm client
server: npm start

然后我创建了一个提交并运行

git push heroku master

我收到以下错误

emote:  !     ERROR: Application not supported by 'heroku/nodejs' buildpack
