reactjs - React 和 Vercel：错误：命令“npm run build”以 1 退出？

Question

我正在尝试将一个简单的 create-react-app 部署到 vercel 并继续获取此构建日志，并在标题中显示错误。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，并且正在尝试部署客户端应用程序。谢谢！

日志显示npm run build脚本由于 lint 警告而引发错误。

这是我在心理上解析日志的方式（...意味着我浏览了该部分）：

...
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    src/common/Header.jsx
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。

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.

build您需要解决源代码中的 linter 警告，或者在运行脚本时找到关闭 linter 的方法（相关）。
