解决方案 #

1. 手动安装指定版本Python 3.11.2 #

• 前往Python官方渠道下载3.11.2版本的安装程序
• 运行安装程序时，务必勾选Add Python to PATH选项，确保系统能识别Python命令
• 安装完成后，打开命令提示符执行python --version或python3 --version验证版本是否正确

2. 修复Chocolatey源与缓存 #

• 以管理员身份打开命令提示符
• 执行choco source list检查当前Chocolatey源是否正常
• 若源存在异常，执行choco source add -n=chocolatey -s="https://community.chocolatey.org/api/v2/"重新添加官方源
• 执行choco cache clean清理Chocolatey本地缓存，避免旧缓存干扰

3. 重新触发依赖安装 #

回到项目根目录，执行对应的包管理命令（如npm install）重新启动依赖安装流程，此时系统会识别到已安装的Python，无需再通过Chocolatey安装
