Node.js MERN应用程序存储到Heroku-未找到package.json

我正在尝试使用Heroku CLI在线获取MERN应用程序。该应用程序在本地运行良好，但当我尝试使用git将该应用程序推送到Heroku上时，会收到以下错误消息：

它的主旨似乎是找不到root package.json文件，尽管它肯定在那里。事实上，这是：

  "version": "1.0.0",
  "description": "",

  "dependencies": {
    "axios": "^0.21.1",

  },

  },

}

我尝试了一个常见的修复方法，手动删除React应用程序目录中的.git文件夹，但似乎没有修复它

整个代码都在Github上

有人能帮忙吗？我已经在这个项目上工作了很长一段时间了，所以在最后关头摔倒真的很令人沮丧。我以前没有做过类似的事情，所以不确定从哪里开始故障排除

谢谢

这可能是问题的根源，也可能不是问题的根源，但您的github回购协议似乎显示git跟踪无效。例如，您的回购缺少整个

客户端

源和

节点_模块

不应被跟踪（

.gitignore

应忽略）。谢谢，这听起来很有希望。。。我做了一个git add--all，它将客户机源中的所有内容添加到下一次提交中，但仍然收到与Heroku相同的错误消息，并推送到Github，但它仍然显示缺少的客户机源，而不是更新的客户机源？很抱歉听起来像个十足的白痴，我也没怎么用git。我还需要根目录中的.gitignore文件吗？（客户端文件夹中有一个，其中有节点_模块……）应该有根

gitignore

。看见有关详细信息，请参见自述。
