“错误：在 React 应用程序的 Vercel 部署中找不到名为“build”的输出目录

Question

我正在尝试在 Vercel 上部署全栈应用程序（Node.js 后端和 React 前端）。但是，我不断遇到错误：

数学 复制代码 错误：构建完成后找不到名为“build”的输出目录。您可以在项目设置中配置输出目录。

{
    "builds": [
        {
            "src": "backend/app.js",
            "use": "@vercel/node"
        },
        {
            "src": "frontend/package.json",
            "use": "@vercel/static-build",
            "config": {
                "distDir": "frontend/build"  // This is where your build folder is located
            }
        }
    ],
    "routes": [
        {
            "src": "/api/(.*)",
            "dest": "/backend/app.js"
        },
        {
            "src": "/(.*)",
            "dest": "/frontend/build/$1"
        }
    ]
}

        "start": "react-scripts start",
        "build": "react-scripts build",
        "test": "react-scripts test",
        "eject": "react-scripts eject"
    },
    "eslintConfig": {
        "extends": [
            "react-app",
            "react-app/jest"
        ]
    },
    "browserslist": {
        "production": [
            ">0.2%",
            "not dead",
            "not op_mini all"
        ],
        "development": [
            "last 1 chrome version",
            "last 1 firefox version",
            "last 1 safari version"
        ]
    }
}

尽管如此，部署还是因缺少构建目录而失败。我已经在前端运行了 npm run build，并且构建文件夹是在本地创建的。如何确保 Vercel 在部署期间使用正确的输出目录？

我有同样的问题，我修改了 vercel.json 文件更改了“builds”，

    "config": {
      "distDir": "build"
    }

还有“路线”，

  {
    "src": "/(.*)",
    "dest": "/frontend/$1"
  }

祝你好运！！！
