我希望使用PyQt6创建我的小型GUI应用程序。我已经安装了PyQt6，但还需要安装PyQt6-tools。因此，当我尝试获取它时，我遇到了以下错误：

ERROR: Cannot install pyqt6-tools==6.0.1.3.2, pyqt6-tools==6.0.2.3.2, pyqt6-tools==6.0.3.3.2 and pyqt6-tools==6.1.0.3.2 because these package versions have conflicting dependencies.

The conflict is caused by:
    pyqt6-tools 6.1.0.3.2 depends on pyqt6-plugins<6.1.0.3 and >=6.1.0.2.2
    pyqt6-tools 6.0.3.3.2 depends on pyqt6-plugins<6.0.3.3 and >=6.0.3.2.2
    pyqt6-tools 6.0.2.3.2 depends on pyqt6==6.0.2
    pyqt6-tools 6.0.1.3.2 depends on pyqt6==6.0.1

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

我知道有依赖问题，但我对pip没有经验，不知道如何解决这个问题。操作系统：Windows 10，Python 3.10

使用Python3.9代替。 - eyllanesc

如eyllanesc所建议的那样，对我来说使用Python3.9很好用。

<PathToPython3.9>\python.exe -m pip install pyqt6_tools

-1

对于那些使用Linux（比如Ubuntu）并且不想回到Python 3.9的人，请使用以下方法：

  1. 如果没有安装flatpak，请执行sudo apt install flatpak
  2. 添加flatpak repo：flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
  3. 安装Qt Designer：flatpak install flathub io.qt.Designer
  4. 安装完成后，在终端中运行designer。
