Python ImportError:没有名为PySide的模块

我已经在我的Ubuntu 12.04中安装了PySide。当我尝试在python控制台中使用import PySide时，我得到了以下错误

import PySide
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named PySide

---

如何解决此问题？

PySide的最新构建和安装说明如下：

---

要使用python 3，只需按照以下说明操作：

在ubuntu 12.04中，这意味着只需在控制台中键入一行：

sudo apt-get install python3-pyside

---

现在，对于

python

versions>3.4x，使用

pip安装pyside2

无法解决名为“PySide”的模块问题，如下所示：

andylu@andylu-Lubuntu-PC:~$ pip install pyside2

在我看来，尝试从终端启动jupyter qtconsole时出错：

andylu@andylu-Lubuntu-PC:~$ jupyter qtconsole
Traceback (most recent call last):
  File "/home/andylu/.pyenv/versions/3.9.0/lib/python3.9/site-packages/qtpy/__init__.py", line 204, in <module>
    from PySide import __version__ as PYSIDE_VERSION  # analysis:ignore
ModuleNotFoundError: No module named 'PySide'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/andylu/.pyenv/versions/3.9.0/bin/jupyter-qtconsole", line 5, in <module>
    from qtconsole.qtconsoleapp import main
  File "/home/andylu/.pyenv/versions/3.9.0/lib/python3.9/site-packages/qtconsole/qtconsoleapp.py", line 60, in <module>
    from qtpy import QtCore, QtGui, QtWidgets
  File "/home/andylu/.pyenv/versions/3.9.0/lib/python3.9/site-packages/qtpy/__init__.py", line 210, in <module>
    raise PythonQtError('No Qt bindings could be found')
qtpy.PythonQtError: No Qt bindings could be found

解决方案是，如上所述，安装

pyside2

，而不是

pyside

：

pip install pyside2

你是如何安装Pyside的？你是如何试图解决你自己的问题的？我遵循了这里指定的步骤[我想我发现了问题，我安装了python3 Pyside，但我使用的是python2.7。在删除python3 Pyside后，我安装了python Pyside，这很好。但它们只参考python2.7，而（至少在理论上）PySide应该使用Python3.2指令适用于所有Python版本（从2.7到3.4），只需将2.7替换为3.2或您正在使用的任何Python版本即可。
