求助：安装webview库失败，无法构建wheel以安装pyproject.toml项目

环境信息 #

• Python 3.11.0
• Windows 10 Pro Version 22H2（OS Build 19045.2728）
• 已安装Microsoft Visual C++ 2015-2022 Redistributable（x86/x64，版本14.32.31326）
• 已更新cmake、wheel、setuptools、pip

错误现象 #

执行pip install --use-pep517 webview时触发编译失败，提示缺少Microsoft Visual C++ 14.0+工具链，即使已安装C++ Build Tools仍无法解决，完整错误日志如下：

C:\Users\Bouregag Youcef>pip install --use-pep517 webview
Collecting webview

      error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for webview

ERROR: Could not build wheels for webview, which is required to install pyproject.toml-based projects

解决步骤 #

仅安装C++ Build Tools默认组件不包含编译Python扩展所需的完整工具链，需手动勾选特定组件：

1. 打开Visual Studio Installer，在「已安装」标签找到「Microsoft Visual C++ Build Tools」，点击「修改」
2. 在组件选择界面，确保勾选以下核心项：
   • MSVC v143 - VS 2022 C++ x64/x86生成工具（根据系统架构选择，优先x64）
   • Windows 10 SDK（选择与你的系统版本匹配的SDK版本，如10.0.19041.0及以上）
   • C++ CMake工具for Windows
3. 点击「修改」完成组件安装，安装结束后重启电脑
4. 重新打开命令提示符/PowerShell，执行pip install --use-pep517 webview重试安装

备选方案 #

若上述方法仍无效，可尝试安装预编译wheel包：

• 找到适配Python 3.11、Windows平台的webview预编译wheel文件
• 执行pip install 本地wheel文件路径完成安装
