我正在尝试将我的应用部署到heroku,并且我一直收到此错误消息,说它"未能检测到应用匹配.......&# 34;推动被拒绝了。我按照它在heroku网站上所说的方式进行了跟踪,并且我一直卡在那个git push heroku master部分我已经尝试做一些我无法找到解决方案的研究。

答案 0 :(得分:1)
这意味着没有将package.json文件签入git项目的根目录,因此Heroku检测到它不是Node.js应用程序。你可以在本地看到这个:
git show master:package.json
要修复它,你需要确保项目的根目录中有一个package.json(还有一个.git目录),并将它添加到git:
git add package.json
git commit -m 'track package.json'
可以改进措辞('未能检测到set buildpack')。应该说'未能检测到Node.js app'。当运行buildpack的“detect”脚本(https://github.com/heroku/heroku-buildpack-nodejs/blob/master/bin/detect)时,它会查找package.json文件以验证是否有可用于构建的节点应用程序。
