You need a package.json file (and a Procfile), it is likely not the case.
您需要一个 package.json 文件（和一个 Procfile），但情况可能并非如此。

I have encountered this issue a few time before and it was because I was trying to push a remote branch to heroku.
我之前遇到过这个问题，这是因为我试图将远程分支推送到 heroku。
To solve the problem, instead of using:
要解决问题，而不是使用：
git push heroku master
I used:
我用了：
git push heroku my-branch:master
This pushes the remote branch my-branchin the git repository to the masterbranch of heroku.
这会将my-branchgit 存储库中的远程分支推送到masterheroku的分支。

Just for the record, I had the same problem and it turned out to be one of the Config Vars in Heroku. I remove the config vars and the app was pushed successfully.
只是为了记录，我遇到了同样的问题，结果证明它是 Heroku 中的配置变量之一。我删除了配置变量并且应用程序被成功推送。
