验证UmiJS框架标识符和配置完整性

需要确认"umijs"是否为Vercel支持的有效框架标识符，并验证这个最小化配置是否满足项目的部署需求。建议检查原始now.json中是否包含其他需要迁移的配置（如构建命令、输出目录、环境变量等）。

请运行以下脚本验证框架配置的有效性：

另外，您可以通过查阅最新的Vercel框架支持文档来确认"umijs"是否为有效的框架标识符：

🏁 Script executed:

#!/bin/bash
# 搜索项目中是否存在now.json或其备份，查看原始配置内容
fd -e json -type f | grep -E "(now|vercel)" | head -20

# 检查package.json中的UmiJS相关依赖
cat package.json | grep -A 5 -B 5 "umi"

🌐 Web query:

Vercel supported frameworks list umijs

💡 Result:

Yes — Vercel lists UmiJS as a supported framework and provides a deployment guide. See Vercel's supported frameworks list and the UmiJS deploy guide. [1][2]

[1] Vercel — Supported Frameworks (includes UmiJS).
[2] Vercel guide: "How to Deploy an UmiJS App with Vercel" (deployment instructions).

需要进一步搜索now.json文件以验证配置完整性。让我运行修正的脚本：

---

🏁 Script executed:

```shell
#!/bin/bash
# 搜索now.json和vercel.json文件
fd -e json -type file | grep -E "(now|vercel)"

# 如果now.json存在，显示其内容
if [ -f "now.json" ]; then
  echo "=== now.json content ==="
  cat now.json
fi

# 如果vercel.json存在，显示其内容
if [ -f "vercel.json" ]; then
  echo "=== vercel.json content ==="
  cat vercel.json
fi

需要验证最小化配置是否充分。让我检查项目的构建配置：

---

🏁 Script executed:

```shell
#!/bin/bash
# 搜索项目中的部署相关配置文件
ls -la | grep -E "(vercel|now|build|\.vercel)"

# 检查是否存在构建或部署相关的环境配置
find . -maxdepth 2 -name ".*" -o -name "*config*" | grep -v node_modules | head -20

# 查看package.json中的build脚本
echo "=== Build scripts ==="
grep -A 2 '"build"' package.json

需要最后确认Vercel对UmiJS最小配置的支持情况：

🌐 Web query:

```web
Vercel UmiJS minimal configuration framework only

💡 Result:

Summary — minimal Vercel setup to deploy an UmiJS app (static output)

1. package.json (scripts)

• Ensure you have a build script that runs Umi:
  {
  "scripts": {
  "build": "npx umi build",
  "dev": "npx umi dev",
  "start": "npx umi dev"
  }
  }

2. vercel.json (minimal, puts Vercel build and serves Umi's dist)

• Create vercel.json at project root:
  {
  "buildCommand": "npx umi build",
  "outputDirectory": "dist"
  }

Notes

• Umi’s production build outputs to dist by default (so outputDirectory = "dist"). [1]
• Vercel will run the buildCommand and serve the files from outputDirectory. Use vercel.json properties buildCommand/outputDirectory to override project settings. [2][3]
• If your Umi app needs server-side Node APIs (not just static files), you’ll need a different configuration (Vercel Functions or a server runtime) — the above is for static-only builds.
