# =============================================================================
# 企微IT智能服务台 — 前端 dev 环境一键安装脚本
# =============================================================================
# 作用:一次性给 4 个前端项目装 pnpm 依赖
# 用法:.\scripts\dev-frontend-install.ps1
# 前置:已装 pnpm (npm install -g pnpm)
# 输出:每个前端在它自己的目录下创建 node_modules
# 注意:首次安装 3-8 分钟,后续 pnpm install 会很快(增量)
