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：

(venv) PS D:\python_project\pyqt6> pip install .\pyqt6_plugins-6.4.2.2.3-cp311-cp311-win_amd64.whl
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。

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：

from PyQt6.QtWidgets import QApplication, QWidget
import sys
from PyQt6 import uic


class UI(QWidget):
    def __int__(self):
        super().__init__()

        uic.loadUi("main.ui", self)


app = QApplication(sys.argv)
window = UI()
window.show()
app.exec()

出错：

D:\python_project\pyqt6\app.py:14: DeprecationWarning: sipPyTypeDict() is deprecated, the extension module should use sipPyTypeDictRef() instead
  window = UI()
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：

from PyQt6 import uic
from PyQt6.QtWidgets import QApplication

Form, Window = uic.loadUiType("main.ui")
app = QApplication([])
window = Window()
form = Form()
form.setupUi(window)  # 配置外观
window.show()
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。
