摘要

本文深入探讨了GraphRAG项目的开发流程，从环境配置、依赖管理到项目构建和测试，全方位展示如何高效地进行GraphRAG项目开发。文章将结合实际案例，详细讲解开发环境搭建、项目构建、测试执行等关键环节，为开发者提供完整的实践指南。

1. 开发环境配置

1.1 环境要求

在这里插入图片描述

mindmap
  root((开发环境))
    基础环境
      Python 3.10-3.12
      操作系统要求
      系统依赖
    开发工具
      Poetry
      代码编辑器
      版本控制
    测试环境
      Azurite
      测试框架
      模拟服务

1.2 环境配置流程

1.3 配置示例

# 环境配置脚本
def setup_development_environment():
    """
    设置开发环境
    """
    import subprocess
    import sys
    
    def check_python_version():
        """
        检查Python版本
        """
        version = sys.version_info
        if not (3, 10) <= version < (3, 13):
            raise RuntimeError(
                f"Python版本必须在3.10-3.12之间，当前版本: {version.major}.{version.minor}"
            )
    
    def install_poetry():
        """
        安装Poetry
        """
        try:
            subprocess.run([
                "curl", "-sSL",
                "https://install.python-poetry.org",
                "|", "python3", "-"
            ], check=True)
        except subprocess.CalledProcessError as e:
            print(f"Poetry安装失败: {str(e)}")
            raise
    
    def setup_project():
        """
        设置项目
        """
        try:
            # 初始化项目
            subprocess.run(["poetry", "init"], check=True)
            
            # 安装依赖
            subprocess.run(["poetry", "install"], check=True)
            
        except subprocess.CalledProcessError as e:
            print(f"项目设置失败: {str(e)}")
            raise

2. 项目依赖管理

2.1 依赖结构

2.2 依赖管理示例

# pyproject.toml配置示例
"""
[tool.poetry]
name = "graphrag"
version = "0.1.0"
description = "GraphRAG项目"
authors = ["Your Name <your.email@example.com>"]

[tool.poetry.dependencies]
python = "^3.10,<3.13"
llm-client = "^1.0.0"
graph-db = "^2.0.0"
vector-store = "^1.0.0"

[tool.poetry.dev-dependencies]
pytest = "^7.0.0"
black = "^22.0.0"
flake8 = "^4.0.0"
mypy = "^0.900"
"""

3. 项目构建流程

3.1 构建流程

3.2 构建脚本

# 构建脚本示例
def build_project():
    """
    构建项目
    """
    import subprocess
    
    def run_checks():
        """
        运行代码检查
        """
        try:
            # 运行格式化检查
            subprocess.run(["poetry", "run", "poe", "check"], check=True)
            
            # 运行类型检查
            subprocess.run(["poetry", "run", "poe", "type_check"], check=True)
            
        except subprocess.CalledProcessError as e:
            print(f"代码检查失败: {str(e)}")
            raise
    
    def run_tests():
        """
        运行测试
        """
        try:
            # 运行单元测试

        assert result.success
        
        # 测试索引查询
        query_result = indexer.query("test query")
        assert len(query_result) > 0
    
    def test_query():
        """
        测试查询功能
        """
        # 初始化查询器
        querier = Querier(config)
        
        # 测试查询执行
        result = querier.execute("test query")
        assert result is not None
        
        # 测试结果验证
        assert result.accuracy > 0.8
