我在尝试部署我的应用程序时遇到问题,我设法将github存储库部署到vercel和heroku中,但是当我打开实时应用程序时,它只显示白屏。

我认为这与我的package.json或类似内容有关。

这是我的package.json:

{
  "name": "marvel-searcher",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "client": "npm start --prefix react-client",
    "dev": "concurrently \"npm run server\" \"npm run client\"",
    "build": "run dev",
    "server": "node server"
  },
  "author": "David Liendo",
  "license": "ISC",
  "dependencies": {
    "axios": "^0.20.0",
    "body-parser": "^1.19.0",
    "cors": "^2.8.5",
    "express": "^4.17.1",
    "md5": "^2.3.0",
    "concurrently": "^5.3.0",
    "dotenv": "^8.2.0"
  },
  "devDependencies": {
    "concurrently": "^5.3.0",
    "dotenv": "^8.2.0",
    "nodemon": "^2.0.4"
  }
}

"server": "node server"更改为"start": "node server",并在项目的根目录中为Heroku创建一个Procfile。

在您的Procfile的第一行中,放入web: npm start

  1. 您可以在 package.json

    上将server":"node server更改为start: node server
  2. 创建 Procfile 并将web: node server.js粘贴到文件上 Heroku将自动运行您的服务器
