如何将 Nextjs 生成的静态站点部署到 Vercel？
How do I deploy a static site generated by Nextjs to Vercel?
我使用Nextjs静态站点生成器输出了一个简单的静态站点。我正在尝试将此站点部署到 Vercel，但在构建过程中我不断收到错误消息。我过去曾将同一个站点部署到静态托管站点，但现在想尝试 Vercel。
nextjs 文档明确指出我的 nextjs 应用需要零配置:
We strongly recommend using Vercel even if your Next.js app is fully static. Vercel is optimized to make static Next.js apps blazingly fast. next export works with Zero Config deployments on Vercel.
这是我的 package.json，部署脚本 运行 npm export 运行s next build && next export 创建 out/ 目录，例如文档推荐：
{
"name": "new-barber-shop",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"dev": "next",
"build": "next build && next export",
"export": "next export",
"start": "next start"
},
"author": "",
"license": "ISC",
"dependencies": {
"@zeit/next-css": "^1.0.1",
"google-maps-react": "^2.0.2",

"react-bootstrap": "^1.0.0-beta.14",
"react-dom": "^16.11.0",
"semantic-ui-react": "^0.88.1"
}
}
这是包含错误的 Vercel 部署构建日志的一部分：

如您所见，它编译成功，但我相信 运行 在尝试导出时出错。有什么想法吗？
这是我的 next.config.js:
module.exports = {
target: 'serverless',
exportPathMap: function() {
return {
'/': { page: '/' }
};
}
};
在本地项目中 运行ning npm run build 时的错误日志（与部署到 Vercel

您的 next.config.js 中可能有 "target": "serverless"。删除它或将其设置为 "target": "server".
Next.js can only handle exporting when the target is set to server (this is the default value). A serverless build, for instance, has no handler for requests–this is usually implemented by a hosting provider.
编辑： 看来错误是由于 Next.js 的旧版本造成的，很可能是因为他们随后将 Zeit（现在的 Vercel）理解为无服务器平台，并且用于覆盖目标。更新版本即可解决问题。还要在 .gitignore 中添加 .next、out 等。 Here is the updated repo.
