无法在WindowsPython3.11中安装PyQt6工具

Question

我在我的Windows11计算机上安装了Python 3.11预发行版：https://www.python.org/downloads/release/python-3110a7/

我把它安装在C:\Python311\文件夹中

然后我启动了一个命令提示符，并安装了wheel、pyqt6和pyqt6-tools。如您所见，安装pyqt6-tools时出了问题

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

× Encountered error while generating package metadata.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

我认为原因可能与访问权有关。所以我在管理模式下启动了一个cmd提示符。不幸的是，问题仍然存在。

我不认为PyQt6与Python3.10或3.11兼容。您必须拥有Python3.9。这就是我所发现的，但也许其他人找到了不同的解决方案。
