React 和 Vercel：錯誤：命令“npm run build”以 1 退出？

Question

我正在嘗試將一個簡單的 create-react-app 部署到 vercel 並繼續獲取此構建日志，並在標題中顯示錯誤。 有人知道怎么修這個東西嗎？ 我分叉並克隆了兩個存儲庫，一個是服務器，另一個是客戶端應用程序，並且正在嘗試部署客戶端應用程序。 謝謝！

日志顯示npm run build腳本由於 lint 警告而引發錯誤。

以下是我在心理上解析日志的方式（ ...表示我瀏覽了該部分）：

...
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，我注意到有關警告被視為錯誤的消息。

其次，由於 lint 規則的格式，我將警告識別為 linter 錯誤： import/no-anonymous-default-export 。

您需要解決源代碼中的 linter 警告，或者在運行build腳本（相關）時找到關閉 linter 的方法。
