简述
Aella Science Dataset Explorer 是一个科学论文数据集的交互式可视化探索工具，基于 React + FastAPI + SQLite 技术栈。项目由 Inference.net 和 LAION 合作开发。
环境要求
必需工具
Python 3.11+ - 后端运行环境
uv - Python 包管理器
bun - JavaScript 运行时和包管理器
Task - 任务运行器
工具安装验证
# 验证安装 python --version # 应该显示 3.11.x 或更高 uv --version # 应该显示版本号 bun --version # 应该显示版本号 task --version # 应该显示版本号完整部署流程
1. 克隆项目
git clone https://gitcode.com/2301_76444133/aella.git cd aella2. 安装工具（如未安装）
安装 uv
pip install uv安装 bun（Windows）
# 方法1：使用 PowerShell powershell -c "irm bun.sh/install.ps1 | iex" # 方法2：如果 PATH 未自动添加，手动添加 # 将 C:\Users\用户名\.bun\bin 添加到系统 PATH 环境变量安装 Task（Windows）
# 方法1：手动下载 # 访问 https://github.com/go-task/task/releases # 下载 task_windows_amd64.zip，解压得到 task.exe # 将 task.exe 放入系统 PATH 或项目根目录 # 方法2：使用 bun 安装 bun add -g @go-task/cli3. 安装项目依赖
task setup这个命令会：
安装后端 Python 依赖（通过 uv）
安装前端 JavaScript 依赖（通过 bun）
4. 下载数据库
task db:setup如果失败，手动下载：
mkdir backend\data curl -L -o backend\data\db.sqlite "https://laion-data-assets.inference.net/db.sqlite"5. 启动后端服务器
task backend:dev如果失败，手动启动：
创建本地服务器文件 (backend/server.py)：

cd backend uv run python server.py6. 启动前端服务器
打开新的命令行窗口：
cd frontend bun run dev7. 访问应用
前端界面：http://localhost:5173
后端 API：http://localhost:8787
API 文档：http://localhost:8787/docs
关键问题与解决方案
问题1：bun 安装后命令未找到
症状：bun --version返回 "'bun' 不是内部或外部命令"
解决方案：
检查安装路径：
C:\Users\用户名\.bun\bin\bun.exe手动添加到 PATH 环境变量
重新启动命令行窗口
问题2：Task 命令未找到
症状：task --version返回命令未找到
解决方案：
将 task.exe 放入系统 PATH 目录
或在项目根目录使用
.\task.exe（如果 task.exe 在项目目录中）
问题3：后端 Cloudflare Workers 依赖错误
症状：ModuleNotFoundError: No module named 'workers'
解决方案：
创建本地 FastAPI 服务器，避免 Cloudflare Workers 特定依赖
使用标准的 SQLite 数据库连接
问题4：前端代理错误
症状：前端控制台显示代理连接错误
解决方案：
确保后端服务器在 8787 端口运行
检查后端 API 接口是否完整实现
修改前端代理配置（如有必要）
问题5：数据库下载失败
症状：task db:setup执行失败
解决方案：
手动创建目录：
mkdir backend\data手动下载数据库文件
检查网络连接和防火墙设置

故障排除指南
快速诊断命令
# 检查后端状态 curl http://localhost:8787/api/papers?limit=1 # 检查前端状态 curl http://localhost:5173 # 检查数据库 python -c "import sqlite3; conn=sqlite3.connect('backend/data/db.sqlite'); print('Tables:', conn.execute('SELECT name FROM sqlite_master WHERE type=\"table\"').fetchall())"常见错误日志分析
端口占用：修改端口号或关闭占用程序
文件权限：以管理员身份运行命令行
依赖冲突：重新安装依赖或使用虚拟环境
网络问题：检查代理设置和防火墙
生产环境部署建议
后端优化
使用 Gunicorn 或 Uvicorn 工作进程
配置反向代理（Nginx）
启用 Gzip 压缩
设置合适的 CORS 策略
前端优化
构建生产版本：
bun run build配置静态文件服务
启用缓存策略
设置 CDN 加速
