Javascript 无法在AWS EC2实例上运行基于NextJS的节点服务器

我已多次尝试运行我的节点服务器，但我收到此错误，为此我尝试删除。下一个文件夹和生成完成后再次生成它会抛出相同的错误。它在我本地的机器上运行得很好

`Could not find a valid build in the '${this.distDir}' directory! Try building your app with 'next build' before starting the server

Error: Could not find a valid build in the '/root/only4laughproject/.next' directory! Try building your app with 'next build' before starting the server.

在执行npm start命令时，它正在运行next build命令，在项目构建完成之前它启动了我的server.js。这就是为什么会出现此问题，我尝试了

下一个构建

在构建完成后，我点击了

节点server.js

。它解决了我的问题。

在启动服务器之前，您是否运行了

next build

？

    "scripts": {
    "dev": "node server.js",
    "build": "next build",
    "start": "npm run-script build && cross-env NODE_ENV=production node server.js",
    "go": "cross-env NODE_ENV=production node server.js"
  }
