ImportError: No module named PySide

Question

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，出现以下错误。

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

我的 Python 路径是：

print sys.path ['', '/usr/lib/python2.7',
'/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk',
'/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload',
'/usr/local/lib/python2.7/dist-packages',
'/usr/lib/python2.7/dist-packages',
'/usr/lib/python2.7/dist-packages/PIL',
'/usr/lib/python2.7/dist-packages/gst-0.10',
'/usr/lib/python2.7/dist-packages/gtk-2.0',
'/usr/lib/pymodules/python2.7',
'/usr/lib/python2.7/dist-packages/ubuntu-sso-client',
'/usr/lib/python2.7/dist-packages/ubuntuone-client',
'/usr/lib/python2.7/dist-packages/ubuntuone-control-panel',
'/usr/lib/python2.7/dist-packages/ubuntuone-couch',
'/usr/lib/python2.7/dist-packages/ubuntuone-installer',
'/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol']

如何解决这个问题？

Answer 1

要使用 python 3，只需按照此处的说明操作：

https://wiki.qt.io/PySide_Binaries_Linux

在 ubuntu 12.04 中意味着只需在控制台中输入一行：

sudo apt-get install python3-pyside

Answer 2

PySide 的最新构建和安装说明在这里：

http://pyside.readthedocs.org/en/latest/building/linux.html

Answer 3

现在，

ModuleNotFoundError: No module named 'PySide'

- 问题可以解决

python

版本> 3.4x与

pip install [pyside<most-recent-version>][1]

（当前版本6）像这样：

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

Successfully installed pyside2-5.15.2 shiboken2-5.15.2

对我来说，尝试从终端启动

jupyter qtconsole

时发生错误：

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

然后，我最初尝试在我当前的

pyside

-环境中安装古老的

Python 3.9.0

，导致以下错误：

andylu@andylu-Lubuntu-PC:~$ pip install pyside
Collecting pyside

它的解决方案是，如上文开头所述，安装

pyside2

而不是

pyside

：

pip install pyside2

编辑： 请注意，pyside 的最新版本可能有所不同，目前是 version 6.
