DNEG xStudio Windows构建：Chocolatey依赖包安装失败求助

在Windows系统上安装DNEG的xStudio视频审阅工具，执行官方构建指南第4步时，使用Chocolatey安装powershell-core、git、cmake三个包均失败，报错信息如下：

推测问题与Python依赖冲突有关，已在管理员Shell中执行操作，寻求解决这三个包的安装问题。

核心问题是Chocolatey本地依赖库存在版本冲突，优先处理Python约束问题，再修复Chocolatey扩展和依赖：

1. 清理Python相关的Chocolatey约束
   打开管理员PowerShell，执行以下命令移除Python的强制版本约束及残留文件：

   choco uninstall python -y --remove-dependencies
   choco uninstall python3 -y --remove-dependencies
   choco cache clean -y
   Remove-Item -Path "C:\ProgramData\chocolatey\lib\python*" -Recurse -Force -ErrorAction SilentlyContinue
   

2. 更新Chocolatey及核心扩展
   先确保Chocolatey本身为最新版本，再强制安装/更新所需扩展：

   choco upgrade chocolatey -y
   choco install chocolatey-core.extension chocolatey-windowsupdate.extension -y --force
   

3. 重新安装目标包
   可一次性安装三个包，若单个包报错，尝试指定兼容版本安装：

   # 一次性安装
   choco install powershell-core git cmake -y --force
   
   # 若git报错，指定兼容版本示例
   choco install git --version=2.42.0 -y
   
   # 若cmake报错，指定兼容版本示例
   choco install cmake --version=3.27.8 -y
   

4. 验证安装结果
   执行以下命令确认包是否安装成功：

   pwsh --version
   git --version
   cmake --version
