Question

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，但是当我尝试使用 git 将应用程序推送到 Heroku 时，我收到以下错误消息：

它的重点似乎是找不到根 package.json 文件，即使它肯定存在。事实上，它是：

"name": "exercise-logger",
  "version": "1.0.0",
  "description": "",
  "main": "server.js",
  "dependencies": {
    "axios": "^0.21.1",
    "bcrypt": "^5.0.1",
    "concurrently": "^6.0.2",
    "config": "^3.3.6",
    "cors": "^2.8.5",
    "express": "^4.17.1",
    "express-validator": "^6.10.0",
    "jsonwebtoken": "^8.5.1",
    "mongoose": "^5.12.3"
  },
  "devDependencies": {},
  "scripts": {
    "start": "node server.js",
    "build": "cd client && npm run build",
    "server": "nodemon server.js",
    "client": "npm start --prefix client",
    "clientinstall": "npm install --prefix client",
    "dev": "concurrently \"npm run start\" \"npm run client\"",
    "heroku-postbuild": "NPM_CONFIG_PRODUCTION=false npm install --prefix client && npm run build --prefix client"
  },
  "engines": {
    "node": "14.x",
    "npm": "6.x"
  },
  "author": "",
  "license": "ISC"
}

我尝试了一个看似常见的修复方法，即手动删除 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 here 上。

有人可以帮忙吗？我已经在这个项目上工作了很长一段时间，所以像这样陷入最后的障碍真的很令人沮丧。我以前从未真正做过这样的事情，所以不确定从哪里开始进行故障排除！

谢谢
