如何在Ubuntu中为Python 3配置PyQt4？

Question

这个问题最初是在askubuntu.com上提出的,但没有引起注意,所以我想也许这是一个更好的问题.

我用synaptic安装了PyQt4.

我正在使用Python3所以我需要在eclipse中配置PyQt4的路径,但似乎synaptic只为python 2安装了PyQt4,因为我只在python 2.6和2.7下找到了相关的文件和文件夹.

那么如何让PyQt4与Python 3和eclipse一起工作呢？

谢谢.

更新:

我尝试按照这篇文章配置它:http://ubuntuforums.org/showthread.php？p = 10914908#post10914908

但是在遵循所有指令后没有发生任何错误的方式,我在python 3.2中运行此代码时收到错误:

>>> import PyQt4

错误消息是:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named PyQt4

但奇怪的是,相同的代码在python 2.7中导致NO错误(我的机器上安装了2.7和3.2)

Answer 1

您应该能够在ubuntu中安装python 3版本的PyQt4.打开终端并输入:

sudo apt-get install python3-pyqt4

这样您就不必从源代码编译Qt4.我也测试了这个,pyqt4与python3一起使用.

安装编译所需的包(我不确定这些都是必需的):

sudo apt install build-essential python3-dev libqt4-dev

下载最新SIP的源代码 - sip-4.12.4.tar.gz(Linux,UNIX,MacOS/X源代码).

解压缩并输入目录:

vic@wic:~/Desktop/sip-4.12.4$ python3 configure.py 
This is SIP 4.12.4 for Python 3.2 on linux2.
The SIP code generator will be installed in /usr/bin.

下载最新的PyQt - PyQt-x11-gpl-4.8.5.tar.gz(Linux,UNIX源代码)的源代码,然后安装它:

请注意,我正在启动python3而不是python.
