Vercel部署报错：Serverless Functions runtime无效（nodejs14.x）求助

更新项目依赖包后，Vercel部署日志报错：“以下Serverless Functions包含无效runtime：index (nodejs14.x)”。本地和Vercel配置的都是Node 18，但项目文件中搜索不到与14相关的配置，请问涉及哪些函数？如何将runtime版本设置为18？

Error: The following Serverless Functions contain an invalid "runtime":
  - index (nodejs14.x). Learn More: https://vercel.com/guides/serverless-function-contains-invalid-runtime-error

涉及的函数 #

报错中明确指向的是名为index的Serverless函数，对应项目中的文件路径通常为：

• 常规Node项目：api/index.js（或.ts）
• Nuxt项目：server/api/index.js（或.ts）

设置runtime为Node 18的方法 #

1. 单个函数文件指定runtime #

在index函数文件的最顶部添加注释，强制指定runtime版本：

// @vercel/node@18
// 或直接标识runtime
// runtime: nodejs18.x

export default function handler(req, res) {
  // 函数业务逻辑
}

2. 全局配置（所有Serverless函数统一生效） #

在项目根目录创建或修改vercel.json文件，添加全局runtime规则：

{
  "functions": {
    // 适配Nuxt项目的server目录结构
    "server/**/*.js": {
      "runtime": "nodejs18.x"
    },
    // 适配常规api目录结构的项目
    "api/**/*.js": {
      "runtime": "nodejs18.x"
    }
  }
}

3. 确认Vercel项目平台配置 #

登录Vercel控制台，进入对应项目的Settings -> General -> Node.js Version，确认已选择18.x版本，保存后重新触发部署。
