　　解决办法：

这个错误提示表明在构建PyQt5-sip时出现了问题，与之前提到的相同。错误信息指出需要安装Microsoft Visual C++ 14.0或更高版本。

你可以按照以下步骤解决问题：

1. 确保你已安装了Microsoft Visual C++ Build Tools。你可以从以下链接中下载并安装：https://visualstudio.microsoft.com/visual-cpp-build-tools/

2. 安装完Visual C++ Build Tools后，尝试重新安装PyQt5。可以使用以下命令：pip install pyqt5

特别是第一步的安装说明：

 下载这个工具后，点击运行，会到如下的界面，选择第一个C++  和右边的选项，然后点击右下角的安装，等待系统自动安装即可。
