我尝试了一些方法来做到这一点:
I tried some ways to do it like:

我尝试过:
sudo aptitude install python-qt4
来自: http: //www.saltycrane.com/blog/2008/01/how-to-install-pyqt4-on-ubuntu-linux/
每次以上安装后，我都会收到错误消息:
Every time after above installations I got error:

>>> import PyQt4
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named PyQt4
我还尝试通过从以下位置下载PyQt4的源进行安装: http://www.riverbankcomputing.co.uk/software/pyqt/download并从以下网站ip饮: http://www.riverbankcomputing.co.uk/software/sip/下载
I also tried to install it from source downloading PyQt4 from:http://www.riverbankcomputing.co.uk/software/pyqt/downloadand sip from: http://www.riverbankcomputing.co.uk/software/sip/download
然后我在安装PyQt4时遇到错误提示:
Then I got error tring to install PyQt4:
$ sudo python configure.py --verbose

我的问题是:在Ubuntu 12.04上安装PyQt4的正确有效方法是什么?
My question is: What is proper and effective way to install PyQt4 on Ubuntu 12.04?
推荐答案
实际上，您在使用时确实为Qt4安装了python绑定:
You did in fact properly install the python bindings for Qt4 when you used:
sudo aptitude install python-qt4
通常应使用发行版提供的软件包-Ubuntu提供的软件包完全可以满足您的需求.
You should usually use the Distribution-provided packages - the Ubuntu-provided packages are perfectly adequate for your needs.
让我感到困惑的是安装Ubuntu软件包后收到的错误.我只是在Ubuntu 12.04安装上尝试过，它对我有用.这向我表明，您当前在系统上安装的Ubuntu在某种程度上已被破坏.
What's puzzling me is the error you got after installing the Ubuntu package. I just tried this on a Ubuntu 12.04 installation and it worked for me. That suggests to me that your current installation of Ubuntu on your system is broken in some way.
您可以尝试完全清除python-qt4软件包并再次重新安装；
You could try completely purging the python-qt4 package and reinstalling it again;
sudo apt-get remove --purge python-qt4
如果您还发出:
sudo apt-get clean
...将从系统中删除所有已下载的软件包文件，因此，当您发出
... that will remove any downloaded package files from the system, so that apt will then download the package file again when you issue a
sudo apt-get install python-qt4
如果仍然无法正常工作，则说明Ubuntu安装确实发生了很奇怪的事情，完全重新安装Ubuntu可能是明智的选择.
If that still doesn't work, then something very odd indeed is going on with your Ubuntu installation, and it might be wise to completely reinstall Ubuntu.
