ImportError：沒有名爲PySide的模塊

Question

我在我的Ubuntu 12.04中安裝了PySide。當我嘗試在python控制檯中使用導入PySide時，出現以下錯誤。

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

我的Python路徑是：

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'] 

如何解決這個問題？對於PySide

使用Python 3，只需按照指示在這裏：

這在Ubuntu 12.04的手段只是在控制檯中輸入一行：

sudo apt-get install python3-pyside
