Vercel 部署错误：命令“npm run build”以 1 退出

Question

我正在 VS Code 中开发一个 React 应用程序。我使用 create-react-app 进行设置。我可以毫无问题地运行该项目npm start。当我尝试使用 Vercel 发布项目时，出现错误：

已经尝试删除node_modules并npm install再次尝试。

Error! Command "npm run build" exited with 1

Answer 1

检查一下你的代码是否没有warnings. 如果有警告，请尝试修复它们并再次部署，或者通过设置为忽略environment variable CI它们false。它看起来像这样：

CI = false

Answer 2

如果您收到此错误：

1. 转到 vercel.com 中的项目设置。
2. 前往将军。
3. 在“构建和开发设置”中，覆盖构建命令并写入CI='' npm run build. 这为我解决了错误。
