Javascript 运行“下一个构建”将提供；错误。在'；中找不到有效的内置文件；。下一个'；“建立目录”；

在托管web应用的远程计算机上运行

next build

（通过

npm run build

）Next@8.1.0不会产生任何问题。 在本地，我已更新到Next@9.1.3（事实上，我一直在尝试各种版本来解决这个问题），运行

next build

可以提供：

➜  src git:(master) ✗ npm run build

> @ build /Users/zavide/WebDev/workspace/src
> next build

> Build error occurred

这让我快发疯了。我以前是如何生成构建的（现在仍然在我的远程机器上），现在却突然不能了？当我无法运行下一个构建时，我应该如何运行下一个构建。没有构建目录，我无法运行任何生产代码

{
  "scripts": {
    "next": "next",
    "build": "next build",
    "start": "next start",
    "prod": "NODE_ENV=production node server.js",
    "test": "mocha"
  },
