升级 PySide6 后出现错误 No module named 'PySide6.QtWidgets'

Question

升级到 PySide6.3.0 后出现错误 ModuleNotFoundError: No module named 'PySide6.QtWidgets'

来源

import sys
from PySide6.QtWidgets import QApplication, QLabel

app = QApplication(sys.argv)
label = QLabel("Hello World!")
label.show()
app.exec()

错误：

$ python3.10 test.py 
Traceback (most recent call last):
  File "test.py", line 2, in <module>
    from PySide6.QtWidgets import QApplication, QLabel
ModuleNotFoundError: No module named 'PySide6.QtWidgets'

PySide6.3.0 似乎有变化。

如何在PySide6.3.0中导入QtWidgets模块？

编辑：

很明显它正在导入 PySide6 包，但它没有导入 QtWidgets、QtGui、QtCore 等包

#!/usr/bin/env python3.10
import sys
import PySide6
from PySide6 import QtWidgets
from PySide6.QtWidgets import (QApplication, QMainWindow, QWidget, QPushButton, QVBoxLayout, QHBoxLayout)
from PySide6 import QtCore
from PySide6.QtCore import (Qt, QSize)

if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    #TODO
    app.exec()

输出：

$ ./test.py
Traceback (most recent call last):
  File "./test.py", line 4, in <module>
    from PySide6 import QtWidgets
ImportError: cannot import name 'QtWidgets' from 'PySide6' (~/.local/lib/python3.10/site-packages/PySide6/__init__.py)

Answer 1

尝试卸载 PySide6 shiboken6 PySide6-Essentials PySide6-Addons 然后重新安装 PySide6

见https://bugreports.qt.io/browse/PYSIDE-1891

Answer 2

@Blackyy 提供的 link 帮助我解决了这个问题。

The problematic bit is because the update doesn't do a 'uninstall/install' and leave some files around, and doesn't override the PySide6 directory with the content of the new two wheels. If you check your site-packages you will see only like 3 modules remained.

当我使用

将PySide6.2.4升级到PySide6.3.0时出现问题

$ python3.10 -m pip install --upgrade pyside6

由于我们正在升级以前的软件包，因此当我们尝试从 pyside6

import 模块时会导致问题

解决方案：

$ python3.10 -m pip uninstall pyside6 pyside6-addons pyside6-essentials shiboken6
$ python3.10 -m pip cache purge
$ python3.10 -m pip install pyside6

有必要在重新安装之前清除 cache 个文件 pyside6 否则它将使用以前的缓存文件并且 import error 使用继续。

Answer 3

$ python3.10 -m pip install --force-reinstall --no-cache-dir pyside6

不需要pip uninstall和pip cache clear

升级 PySide6 后出现错误 No module named 'PySide6.QtWidgets'

After upgrading PySide6 gives error No module named 'PySide6.QtWidgets'
