Heroku上的Node.js应用需要在目录结构的根目录处输入“ package.json”

Question

我正在尝试将我的api上传到网络上，听说'Heroku'是一个很好的免费云平台。我做有package.json：

构建日志：

-----> App not compatible with buildpack: https://buildpack-registry.s3.amazonaws.com/buildpacks/heroku/nodejs.tgz

 !     ERROR: Application not supported by 'heroku/nodejs' buildpack
 !     
 !     The 'heroku/nodejs' buildpack is set on this application, but was
 !     unable to detect a Node.js codebase.
 !         
 !     A Node.js app on Heroku requires a 'package.json' at the root of
 !     the directory structure.
 !     
 !     If you are trying to deploy a Node.js application, ensure that this
 !     file is present at the top level directory. This directory has the
 !     following files:
 !     
 !     Bezeq.js
 !     Cellcom.js
 !     Hot.js
 !     MainAPI.js
 !     node_modules/
 !     package-lock.json
 !     Partner.js
 !         
 !     If you are trying to deploy an application written in another
 !     language, you need to change the list of buildpacks set on your
 !     Heroku app using the 'heroku buildpacks' command.
 !         
 !     For more information, refer to the following documentation:
 !     https://devcenter.heroku.com/articles/buildpacks
 !     https://devcenter.heroku.com/articles/nodejs-support#activation
       More info: https://devcenter.heroku.com/articles/buildpacks#detection-failure
 !     Push failed

为什么不起作用？
谢谢

Answer 1

您是否在项目的根目录下运行了“ npm init”来创建package.json？

Answer 2

我已修复它，问题出乎意料了-在package.json文件中。 我运行了'npm init'，但是这次更加小心，并注意到了一些小细节。 在那之后，我再次尝试进行部署并且成功了。 谢谢阿里的指导

遇到了同样的问题，但我的解决方案与另一个问题有关，我认为其他人可能会从中受益。 推送必须在您的主分支或分支上：main

git push heroku <your_branch>:main
