我试图同时使用同时运行服务器和客户端，然后我得到了这个错误，即使我在网上尝试了很多解决方案，检查了没有 5000 端口在运行，删除模块，yarn.lock，清理缓存，重新启动我的电脑等，错误仍然存​​在。

包.json

{
  "name": "SPACEX_LAUNCH_STATS",
  "version": "1.0.0",
  "description": "App that lists SpaceX launch missions",
  "main": "server.js",
  "scripts": {
    "start": "node server.js",
    "server": "nodemon server.js",
    "client": "yarn start --prefix client",
    "dev": "concurrently \"yarn run server\" \"yarn run client\""
  },
  "author": "admin",
  "license": "MIT",
  "dependencies": {
    "axios": "^0.21.1",
    "concurrently": "^6.2.0",
    "express": "^4.17.1",
    "express-graphql": "^0.12.0",
    "graphql": "^15.5.1"
  },
  "devDependencies": {
    "nodemon": "^2.0.7"
  }
}

可疑的一件事是我能够杀死所有端口，但有一个是不可杀死的。它说“没有这样的过程”。我不确定这是否是隐藏在幕后某处的正在运行的端口。这是屏幕截图。请帮忙。

没有这个过程

我改为 "dev": "concurrently \"yarn run server\" \"yarn run client\""， "dev": "concurrently \"npm run server\" \"npm run client\""现在一切正常。我不知道为什么，但是端口 3000 和 5000 现在都可以运行
