    Windows11 python3.12 安装pyqt6比较容易，但pyqt6-tools一直安装不上去。出错信息如下：

    找了一圈，终于找到了解决办法，用python3.11的插件包进行安装，有了环境，就可以正常安装pyqt6-tools了。

    如果不想做下面的自己动手步骤，可以看文章顶部的下载资源，直接下载后安装即可。

    pyqt6的插件下载地址如下：

    pyqt6-plugins · PyPI

    看上图，目前只有cp311，就是python3.11的版本，还没有python3.12的版本。那就用这个插件包，可行的原因可能是差别不大？

    下载后的文件名是：pyqt6_plugins-6.4.2.2.3-cp311-cp311-win_amd64.whl

    打开winrar，把这个拖进去，找到info文件夹，里面有个METADATA文件，拖出来，用记事本修改里面的信息。

    把Requires-Dist: pyqt6 后面的限定版本删去，修改为下面这样。

     保存，然后替换压缩包里的同名文件。在终端里，使用pip install 安装这个whl文件，安装前，必须要改名，因为文件名里有cp311，跟系统python3.12版本不一样，会出现错误：

    1. (venv) PS D:\python_project\pyqt6> pip install .\pyqt6_plugins-6.4.2.2.3-cp311-cp311-win_amd64.whl
    2. ERROR: pyqt6_plugins-6.4.2.2.3-cp311-cp311-win_amd64.whl is not a supported wheel on this platform.

    修改文件名为：pyqt6_plugins-6.4.2.2.3-py3-none-any.whl，再pip install 进行安装。

    1. (venv) PS D:\python_project\pyqt6> pip install .\pyqt6_plugins-6.4.2.2.3-py3-none-any.whl  -i https://pypi.tuna.tsinghua.edu.cn/simple/

    尾部加上清华的镜像，速度飞快啊，建议安装任何包都可以加上这个后缀，就是pip install xxx 后面加上：

    -i https://pypi.tuna.tsinghua.edu.cn/simple/

    这个时候再安装pyqt6-tools一路顺畅。

     pip install pyqt6-tools  -i https://pypi.tuna.tsinghua.edu.cn/simple/

    我是在env里安装的，qt designer在 qt6_application文件夹里。

    可以发送快捷方式到桌面。打开设计一个窗体。存储到工程文件夹里，命名main.ui。

    使用命令把ui设计文件转换成python代码：

    pyuic6 -x main.ui -o win.py

    直接运行这个win.py文件就可以了，里面都是自动转换成python的代码。

    直接运行：

    还可以加载ui来运行。

    使用教程里的代码：

    1. from PyQt6.QtWidgets import QApplication, QWidget
    2. import sys
    3. from PyQt6 import uic
    4.  
    5.  
    6. class UI(QWidget):
    7.     def __int__(self):
    8.         super().__init__()
    9.  
    10.         uic.loadUi("main.ui", self)
    11.  
    12.  
    13. app = QApplication(sys.argv)
    14. window = UI()
    15. window.show()
    16. app.exec()

    出错：

    1. D:\python_project\pyqt6\app.py:14: DeprecationWarning: sipPyTypeDict() is deprecated, the extension module should use sipPyTypeDictRef() instead
    2.   window = UI()
    3. libpng warning: iCCP: cHRM chunk does not match sRGB

    使用很多教程里面的，都是出现上面这样的错误。

    终于找到一个可以正常运行的：

    1. from PyQt6 import uic
    2. from PyQt6.QtWidgets import QApplication
    3.  
    4. Form, Window = uic.loadUiType("main.ui")
    5. app = QApplication([])
    6. window = Window()
    7. form = Form()
    8. form.setupUi(window)  # 配置外观
    9. window.show()
    10. app.exec()  # 转交控制权给pyQt6

    上面的代码里form.setupUi(window)  # 配置外观这一句，是不是有点自己加载自己的感觉啊？我这萌新已经一头浆糊了。
