VScode安裝配置PYQT6

開始是準備安裝PYQT5的，但是安裝不下去，就改成安裝PYQT6

一.安裝pyqt5，成功。
c:\PYQT>pip install pyqt5

二.安裝 pyqt5-tools，失敗

因為我的python版本太高，但是降到低版本也失敗
c:\PYQT>python -V
Python 3.13.2
c:\PYQT>pip install python==3.9.0
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement python==3.9 (from versions: none)
ERROR: No matching distribution found for python==3.9.0
去https://www.python.org/downloads/windows/ 上面沒有找到3.9版本的下載包

三.既然如此，安裝pyqty6
c:\PYQT>pip install pyqt6

Solution 1: Package Installation with --user Option

原因是but still limited the maximum path length (which includes the full folder path and the file name) to 260 characters
修改注冊表
計算機\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem ，LongPathsEnabled的0改成1

Successfully installed PyQt6-Qt6-6.8.2 PyQt6-sip-13.10.0 pyqt6-6.8.1

四.安裝pyqty6-plugins插件
c:\PYQT>pip install pyqt6-plugins
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement pyqt6-plugins (from versions: none)
ERROR: No matching distribution found for pyqt6-plugins
但是pyqt6-plugins不支持python 3.12的pip安裝，所以無法使用pip簡單安裝，查了別人的方案，還是停麻煩的。
a.https://pypi.org/project/pyqt6-plugins/#files 下載最新版本
b.用winrar打開修改里面的medata文件，將Requires-Dist: pyqt6后面的版本號限制去掉
Requires-Dist: pyqt6
Requires-Dist: pyqt6-qt6 (==6.4.3)
Requires-Dist: qt6-tools (<6.4.3.2,>=6.4.3.1.2)
c.將修改號的文件拷貝到安裝目錄下，安裝
c:\PYQT>pip install pyqt6_plugins-6.4.2.2.3-cp311-cp311-win_amd64.whl
Defaulting to user installation because normal site-packages is not writeable
ERROR: pyqt6_plugins-6.4.2.2.3-cp311-cp311-win_amd64.whl is not a supported wheel on this platform.
原因是除了修版本顯示還不行，還需要修改文件名，修改后再次安裝

六.安裝成功后，找到兩個路徑，這兩個路徑在vscode中pyqt integration設置中要用到
c:\users\admin\appdata\local\packages\pythonsoftwarefoundation.python.3.13_qbz5n2kfra8p0\localcache\local-packages\python313\site-packages
C:\Users\admin\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.13_qbz5n2kfra8p0\LocalCache\local-packages\Python313\site-packages\qt6_applications\Qt\bin

七.打開VSCODE，在插件中安裝pyqt integration，安裝后設置路徑
Pyqt-integration ? Pyuic: Cmd
'pyuic' command file, you can also specify a path
Pyqt-integration ? Qtdesigner: Path
Path of QT designer

八.調整安裝路徑和重新安裝
在Vscode中創建一個文件，右鍵用PYQT:New Form打開，就可以使用設計圖形界面了。
可能會遇到錯誤，主要還是pyqt integration設置中的路徑問題。
Error: Command failed: "C:\Users\admin\appdata\local\packages\pythonsoftwarefoundation.python.3.13_qbz5n2kfra8p0\localcache\local-packages\python313\site-packages\qt6_applications\Qt\bin"
'"C:\Users\admin\appdata\local\packages\pythonsoftwarefoundation.python.3.13_qbz5n2kfra8p0\localcache\local-packages\python313\site-packages\qt6_applications\Qt\bin"'?
??

為什么我的安裝路徑這么深，我需要重裝一遍

c:\PYQT>python -m site
sys.path = [
? ? 'c:\\PYQT',
? ? 'C:\\Program Files\\WindowsApps\\PythonSoftwareFoundation.Python.3.13_3.13.752.0_x64__qbz5n2kfra8p0\\python313.zip',
? ? 'C:\\Program Files\\WindowsApps\\PythonSoftwareFoundation.Python.3.13_3.13.752.0_x64__qbz5n2kfra8p0\\DLLs',
? ? 'C:\\Program Files\\WindowsApps\\PythonSoftwareFoundation.Python.3.13_3.13.752.0_x64__qbz5n2kfra8p0\\Lib',

? ? 'C:\\Users\\admin\\AppData\\Local\\Packages\\PythonSoftwareFoundation.Python.3.13_qbz5n2kfra8p0\\LocalCache\\local-packages\\Python313\\site-packages',
? ? 'C:\\Program Files\\WindowsApps\\PythonSoftwareFoundation.Python.3.13_3.13.752.0_x64__qbz5n2kfra8p0\\Lib\\site-packages',
]
USER_BASE: 'C:\\Users\\admin\\AppData\\Local\\Packages\\PythonSoftwareFoundation.Python.3.13_qbz5n2kfra8p0\\LocalCache\\local-packages' (exists)
USER_SITE: 'C:\\Users\\admin\\AppData\\Local\\Packages\\PythonSoftwareFoundation.Python.3.13_qbz5n2kfra8p0\\LocalCache\\local-packages\\Python313\\site-packages' (exists)
ENABLE_USER_SITE: True

新建環境變量PYTHONUSERBASE，然后再次執行，可以看到路徑變了。
C:\PYQT>python -m site
sys.path = [
? ? 'C:\\PYQT',
? ? 'C:\\Program Files\\WindowsApps\\PythonSoftwareFoundation.Python.3.13_3.13.752.0_x64__qbz5n2kfra8p0\\python313.zip',
? ? 'C:\\Program Files\\WindowsApps\\PythonSoftwareFoundation.Python.3.13_3.13.752.0_x64__qbz5n2kfra8p0\\DLLs',

? ? 'C:\\Program Files\\WindowsApps\\PythonSoftwareFoundation.Python.3.13_3.13.752.0_x64__qbz5n2kfra8p0\\Lib\\site-packages',
]
USER_BASE: 'C:\\PYQT' (exists)
USER_SITE: 'C:\\PYQT\\Python313\\site-packages' (doesn't exist)
ENABLE_USER_SITE: True

然后重新操作再安裝一遍
C:\PYQT>pip install pyqt6
C:\PYQT>pip install pyqt6_plugins-6.4.2.2.3-py3-none-any.whl
C:\PYQT>pip install pyqt6-tools
后續更改vscode中的兩個路徑（vscode中pyqt integration）
C:\PYQT\Python313\Scripts
C:\PYQT\Python313\site-packages\qt6_applications\Qt\bin
