"""Tauri 桌面版编译脚本。 用法： python scripts/build_tauri.py # 编译当前系统的桌面版 python scripts/build_tauri.py --platform windows # 指定平台（windows/linux/macos） 特性： - Windows 安装包内置 WebView2 离线安装器（tauri.conf.json 已配置 offlineInstaller）， 适合无外网、未预装 WebView2 Runtime 的机器。 - Windows NSIS 安装器默认安装到 D:\\Program Files\\CapacityReport（无 D 盘时回落系统盘）。 - 跨平台限制：Tauri 无法可靠跨系统交叉编译，--platform 必须与当前系统一致，否则会提示需在目标系统本机构建。 产物：dist/desktop/ 下的安装包（Windows: .msi/.exe；Linux: .deb/.AppImage；macOS: .dmg）。 """ from __future__ import annotations import argparse import json import shutil import sys from pathlib import Path
