Question

我正在尝试将MERN堆栈应用程序部署到Heroku，我已经在package.json文件上进行了必要的配置，我已经在仪表板Heroku上尝试了Heroku CLI和Github Deploy，但是由于某种原因它没有部署...我有heroku postbuild脚本，我检查了多个站点并确认了
这是我的package.json;

{
  "name": "devconnector",
  "version": "1.0.0",
  "description": "Social Network for Developers",
  "main": "server.js",
  "scripts": {
    "start": "node server",
    "server": "nodemon server",
    "client": "npm start --prefix client",
    "dev": "concurrently \"npm run server\" \"npm run client\"",
    "heroku-postbuild": "NPM_CONFIG_PRODUCTION=false npm install --prefix client && npm run build --prefix client"
  },
  "engines": {
    "node": "14.11.0"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "bcryptjs": "^2.4.3",
    "config": "^3.3.2",
    "express": "^4.17.1",
    "express-validator": "^6.6.1",
    "gravatar": "^1.8.1",
    "jsonwebtoken": "^8.5.1",
    "mongoose": "^5.10.7",
    "request": "^2.88.2"
  },
  "devDependencies": {
    "concurrently": "^5.3.0",
    "nodemon": "^2.0.4"
  }
    }

这是错误日志；
