我试图在next.js中获得一个生产构建来在我的服务器上运行它，但当我尝试时，我无法构建next.js生产构建
npm运行构建
有人知道如何让next.js中的产品构建正常工作吗？我在next.js文档中做了所有工作，但总是在下面出现这个错误。如果我进行开发构建，它运行得很好，但尝试prod构建会导致错误。
我还多次下一次构建，并重新安装了仍然存在此错误的所有node_modules包。
它总是在终端中显示我
Error: Could not find a valid build in the '/mnt/c/Users/NZXT_YOLO/Desktop/New folder (2)/learnnextjs-demo/.next' directory! Try building your app with 'next build' before starting the server.

我计划在我的AWS服务器上使用node运行这个next.js站点。但要做到这一点，我需要获得react.js的生产构建，目前我只能运行一个开发构建。
next build后面跟着next start应该是为生产准备构建并运行它的正确命令。
下面是package.json的一个示例。如果您想导出应用程序以作为静态内容运行，比如将其作为静态网站托管在s3中，则需要运行next export
...
"scripts": {
"build": "next build",
"start": "next start",
"export": "next export"
}
...
确保您的package.json中有上述脚本，然后按顺序运行以下
$ npm run build
$ npm run start
若要用特定端口启动应用程序，可以指定-p端口作为npm run命令的参数
npm run start -- -p 3232
如果您想将其合并到CI/CD管道中，则需要Dockerfile，下面是一个简单的示例
FROM node:alpine
#copy source
COPY . /app
# Install deps
RUN cd /app && npm install
# Build
RUN npm run build
ENTRYPOINT [ "npm", "run", "start" ]
仍然需要更多的解释或帮助，请随时留言，我将非常乐意为您提供帮助。
似乎您的server.js配置不正确。请尝试将您所有的next.config.js移动到server.js，确保next.config.js文件为空，然后创建一个新的npm运行脚本：
"prod_start": "NODE_ENV=production node server.js"
你的package.json应该是这样的：
{
"name": "hello-next",
"version": "1.0.0",
"description": "",
"main": "server.js",
"scripts": {
"dev": "node server.js",
"build": "next build",
"prod_start": "NODE_ENV=production node server.js",
"export": "next export"
},
"keywords": [],
"author": "",
"license": "ISC",
"dependencies": {
"@zeit/next-sass": "^1.0.1",
"express": "^4.16.4",
"next": "^7.0.2",
"react": "^16.6.3",
"react-dom": "^16.6.3",
"redux": "^4.0.1",
"video-react": "^0.13.1"
}
}
确保运行：npm run build && npm run prod_start
然后，您应该使用next.js 运行react的生产构建
如果您有问题，请告诉我。
您必须在根文件夹中而不是在.next/中启动next build
有三种方法：-
方法1：使用next build而不是npm run build
方式2:npm run buildnpm install -g serveserve -s build更多信息：https://create-react-app.dev/docs/deployment/
方法3：在npm run build之后，从JS中删除/，从/static/index.html文件中删除CSS链接。更换这两条
<script defer="defer" src="/static/js/main.aa87bc08.js"></script>
<link href="/static/css/main.073c9b0a.css" rel="stylesheet"/>
这两条线
<script defer="defer" src="static/js/main.aa87bc08.js"></script>
<link href="static/css/main.073c9b0a.css" rel="stylesheet" />
现在它甚至还在工作file:///D:/codes/ProjectName/build/index.html
在评论中告诉我，如果这3种方法都不起作用，我会找到，尝试&告诉方式4、5等
