根据您提供的错误信息，看起来在尝试安装 Jupyter Notebook 的过程中，遇到了构建 pywinpty 轮子时的问题。这似乎与 Rust 编译器和 Windows 系统上的交叉编译配置有关。

为了解决这个问题，您可以按照以下步骤操作：

1. 确保已安装 Rustup： 如果还没有安装 Rustup，请访问 https://www.rust-lang.org/tools/install 并按照指南安装它。Rustup 是 Rust 编程语言的包管理器和工具链管理器。

2. 安装 i686-pc-windows-msvc 构建工具： 在安装了 Rustup 后，运行以下命令来添加 i686-pc-windows-msvc 构建工具：

   rustup target add i686-pc-windows-msvc
   

   这将下载并安装用于构建 x86（32位）Windows 应用程序所需的工具链。

3. 重新安装 pywinpty： 删除现有的 pywinpty 安装，并且再次尝试安装。在命令提示符或 PowerShell 中执行以下命令：

   pip uninstall pywinpty
   pip install pywinpty
   

4. 检查环境变量： 确保您的系统环境变量中没有错误地设置了 RUSTUP_HOME 或 CARGO_HOME，这些可能会干扰 Rustup 和 Cargo 的正常工作。

5. 更新 Python 环境： 尝试更新 pip 到最新版本，然后重新安装 Jupyter Notebook 和其依赖项：

   python -m pip install --upgrade pip
   python -m pip install jupyter notebook
   

按照上述步骤操作后，应该可以成功安装 Jupyter Notebook。如果问题仍然存在，请提供进一步的错误信息，以便我能为您提供更具体的帮助。
