由于 Webpack 错误，nextJS 在 Vercel 上构建失败

Question

我正在尝试部署到 Vercel 我之前在其他项目中做过，但在这种情况下，构建失败，它提到它没有找到 Footer 组件，构建在本地机器上运行完美。

Answer 1

我得到了支持的帮助，似乎即使我的本地组件大写，远程分支也有一些组件小写。

Answer 2

我也有类似的问题。它在本地构建得很好，但在 vercel 上构建时失败。

我做了一些测试，发现问题与路径总长度+文件名有关。

我组织了我的 apollo 查询，以便它们位于与集合 tey 查询同名的文件夹中。文件名是描述性的。结果是长路径和文件名。

一个例子


09:53:38.510    Failed to compile.
09:53:38.510    ModuleNotFoundError: Module not found: Error: Can't resolve 'urbalurba/apollo/queries/entitynetmember/EntityNetworkMembershipByEntityIDandNetworkID' in '/vercel/workpath0/urbalurba/lib'
09:53:38.510    > Build error occurred
09:53:38.511    Error: > Build failed because of webpack errors
09:53:38.511        at build (/vercel/workpath0/node_modules/next/dist/build/index.js:15:918)
09:53:38.511        at runMicrotasks (<anonymous>)
09:53:38.511        at processTicksAndRejections (internal/process/task_queues.js:97:5)

如您所见，保存我的 graphql 突变的文件具有长文件名 EntityNetworkMembershipByEntityIDandNetworkID 上例中的文件夹是entitynetmember.

我将文件夹名称从 entitynetworkmembership 缩短为 entitynetmember。这样做之后，该文件夹中的所有其他文件都被构建过程找到了。

所以我的结论是总长度是导致构建失败的原因。

Answer 3

确保您使用准确的 folder/file 名称正确导入组件。例如，如果您有一个名为 main 和 index.js 的文件夹，则将其导出为组件。您必须从确切的文件夹名称（区分大小写）

中导出 Main 组件

// Content of index.js inside main folder
export default function Main() {}

// Use main component like this:

import Main from "./main";

export default function Home() {
  return <Main />;
}

Answer 4

我遇到同样的问题，删除 .next 文件夹并重建新版本。

Answer 5

我也遇到了 Vercel 构建错误（并且在本地主机中没有问题运行），这是一个大写问题。当我尝试将 Comment 组件导入页面时，我遇到了 Vercel 构建错误：

Failed to compile.
./pages/{mypage.js}
Module not found: Can't resolve '../components/comment' in '/vercel/path0/pages/'

> Build failed because of webpack errors
error Command failed with exit code 1.

我终于通过将评论组件大写解决了。如果我更改页眉或页脚组件的大小写以匹配评论组件，则会出现相同的错误。这就是我最终需要做的来消除构建错误...

import Comment from '../components/Comment'; //updated this import from comment to Comment
import Header from '../components/header'
import Footer from '../components/footer'

由于 Webpack 错误，nextJS 在 Vercel 上构建失败
