无法在 Windows 上的 Python 3.11 中安装 PyQt6 工具

我安装了Python 3.11在我的 Windows 11 计算机上预发布：https://www.python.org/downloads/release/python-3110a7/ https://www.python.org/downloads/release/python-3110a7/

我安装在文件夹里C:\Python311\

然后我启动了命令提示符并安装wheel, pyqt6 and pyqt6-tools。正如你所看到的，安装时出现了问题pyqt6-tools:

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

我认为原因可能与访问权限有关。所以我在管理模式下启动了cmd提示符。不幸的是，问题依然存在。

这是在 Python 3.11 上安装 pyqt6 的完整指南

1. 从 pypi 下载文件。这是链接：https://pypi.org/project/PyQt6/#files https://pypi.org/project/PyQt6/#files。下载名为“PyQt6-6.4.1-cp37-abi3-win_amd64.whl”的 Windows 版本
2. 将文件重命名为“PyQt6-6.4.1-py3-none-win_amd64.whl”
3. 现在也从 pypi 下载插件文件。这是链接：https://pypi.org/project/pyqt6-plugins/#files https://pypi.org/project/pyqt6-plugins/#files。下载名为“pyqt6_plugins-6.1.0.2.2-cp39-cp39-win_amd64.whl”的文件
4. 将最后一个文件重命名为“pyqt6_plugins-6.1.0.2.2-py3-none-win_amd64.whl”
5. 现在，使用 WinRar （或类似的）打开最后一个文件，该文件现在被重命名为“pyqt6_plugins-6.1.0.2.2-py3-none-win_amd64.whl”
6. 打开文件夹“pyqt6_plugins-6.1.0.2.2.dist-info”
7. 使用文本编辑器打开文件“METADATA”
8. 找到行：“Requires-Dist: pyqt6 (==6.1.0)”并更改为“Requires-Dist: pyqt6”。保存文件。
9. 现在你的 2 个文件已经准备好了，你只需要手动 pip install 这些文件：

pip 安装 PyQt6-6.4.1-py3-none-win_amd64.whl

pip 安装 pyqt6_plugins-6.1.0.2.2-py3-none-win_amd64.whl

10. 完毕！你已经在Python 3.11中安装了Pyqt6！

所有功劳归用户所有https://github.com/liudonghua123 https://github.com/liudonghua123这解决了 pyqt5 中的这个问题https://github.com/altendky/pyqt-tools/issues/108 https://github.com/altendky/pyqt-tools/issues/108，这只是相同的解决方案，但应用于 pyqt6。
