React 和 Vercel:错误:命令“npm run build"以 1 退出? [英] React and Vercel: Error: Command "npm run build" exited with 1?

问题描述

我正在尝试将一个简单的 create-react-app 部署到 vercel 并不断获取此构建日志，其中包含标题中的错误.有人知道怎么修这个东西吗?我分叉并克隆了两个存储库，一个是服务器，另一个是客户端应用程序，我正在尝试部署客户端应用程序.谢谢！

I am trying to deploy a simple create-react-app to vercel and keep getting this build log with the error in the title. Anyone know how to fix this? I forked and cloned two repos, one being a server and the other being a client app, and am trying to deploy the client app. Thanks!

推荐答案

日志显示 npm run build 脚本由于 lint 警告而引发错误.

The logs show that the npm run build script is throwing an error because of lint warnings.

以下是我在精神上解析日志的方式(... 意味着我浏览了该部分):

Here's how I mentally parse the logs (... means I skimmed over that section):

...
19:02:37.053    Installing dependencies...
...
19:03:05.918    Running "npm run build"
...
19:03:12.854    Treating warnings as errors because process.env.CI = true.
...

19:03:12.855      Line 4:1:  Assign arrow function to a variable before exporting as module default  import/no-anonymous-default-export
...
19:03:12.898    Error: Command "npm run build" exited with 1
...

首先，我注意到有关警告被视为错误的消息.

First, I noticed the message about warnings being treated as errors.

其次，由于 lint 规则的格式，我将警告识别为 linter 错误:import/no-anonymous-default-export.

Second, I recognized the warnings as linter errors because of the format of the lint rule: import/no-anonymous-default-export.

您需要解决源代码中的 linter 警告或找到一种在运行 build 脚本时关闭 linter 的方法 (相关).

You need to address the linter warnings in your source code or find a way to turn off the linter when running the build script (related).
