解决方案 #

1. 补全Visual Studio Build Tools组件 #

string.h是Windows SDK提供的标准C头文件，找不到说明你的VS Build Tools缺少必要组件：

• 打开Visual Studio Installer，找到已安装的"Visual Studio Build Tools 2019"，点击"修改"
• 在"工作负载"选项卡，确保勾选**"C++生成工具"**
• 切换到"单个组件"选项卡，搜索并勾选对应你系统版本的**"Windows SDK"**（如Windows 10 SDK 19041及以上）
• 完成安装后重启命令提示符，再执行pip install python-axolotl-curve25519

2. 使用预编译二进制轮子跳过编译 #

如果不想配置编译环境，可以直接安装预编译的轮子文件：

• 确认你的Python版本和系统架构（比如Python 3.9 64位）
• 下载对应版本的.whl格式轮子文件
• 执行本地安装命令：

  pip install 本地轮子文件路径\python_axolotl_curve25519-0.4.1.post2-cp39-cp39-win_amd64.whl
  

3. 降级Python版本（可选） #

旧版python-axolotl-curve25519可能和Python 3.9兼容性不佳，可尝试降级到Python 3.8后再执行安装命令。
