在Python 3.12.3上安装pyqt-tools时出错

Question

我尝试安装 PyQt5 和 PyQt6。在这两种情况下，PyQt 本身都正常安装，但 PyQt-Tools（5 或 6）给出错误“元数据生成失败”。我的Python版本是3.12.3，我使用的是pip 24.0。

错误：

  note: This error originates from a subprocess, and is likely not a problem with pip.

我在网上才发现我需要最新版本的Python（我已经有了），并且PyQt5与Mac上的M1不兼容（我已经尝试安装第五和第六版本，此外，我有一台装有 Windows 和 Intel 的笔记本电脑）。

Answer 1

您可能需要降级您的Python，因为pyqt5-tools和pyqt6-tools都支持Python 3.5 - 3.9。

此外，建议使用 virtualenv 或 venv 创建隔离环境来安装依赖项。
