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！

日志显示 npm run build 脚本由于 lint 警告而引发错误。
以下是我在心理上解析日志的方式（... 表示我略读了该部分）：

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。
在运行 build 脚本 (related) 时，您需要解决源代码中的 linter 警告或找到关闭 linter 的方法。
