Python 2.7 cannot import PyQt4
提问by Austin Adams
I've upgraded to Python 2.7 from Python 2.6 on Ubuntu Maverick Meerkat (10.10) and I'm unable to import PyQt4.
我已在 Ubuntu Maverick Meerkat (10.10) 上从 Python 2.6 升级到 Python 2.7，但无法导入 PyQt4。
austin@gerald:~$ python2.7
Python 2.7.0+ (r27:82500, Sep 15 2010, 18:04:55)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import PyQt4
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named PyQt4
I installed both Python 2.7 (python2.7) and PyQt4 (python-qt4) from the Ubuntu repositories. I installed PyQt a while back, but I installed Python 2.7 recently.
我从 Ubuntu 存储库安装了 Python 2.7 (python2.7) 和 PyQt4 (python-qt4)。不久前我安装了 PyQt，但最近我安装了 Python 2.7。
If I try Python 2.6 (since it's shipped with Ubuntu, the command is simply python), it works perfectly. Watch:
如果我尝试使用 Python 2.6（因为它是随 Ubuntu 一起提供的，命令就是python），它可以完美运行。手表：
austin@gerald:~$ python
Python 2.6.6 (r266:84292, Sep 15 2010, 15:52:39)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import PyQt4
I know what the problem is: the PyQt4 modules are accessible by Python 2.6 but not 2.7. My question is, how do I get Python 2.7 to find the PyQt4 module(s)? Help!
我知道问题是什么：Python 2.6 可以访问 PyQt4 模块，但不能通过 2.7 访问。我的问题是，如何让 Python 2.7 找到 PyQt4 模块？帮助！
Note: sorry if this belongs in Super User, I was just programming when I encountered this problem.
注意：对不起，如果这属于超级用户，我遇到这个问题时只是在编程。

You should install PyQt4 in the Python 2.7 environment. To do this run
您应该在 Python 2.7 环境中安装 PyQt4。要执行此运行

If easy_install is not installed you will need to first download and install it by running
如果未安装easy_install，您需要先下载并运行以下命令安装它
python2.7 setup.py install

As PyQt is not using setup.py it cannot be installed using pip or easy_install
由于 PyQt 不使用 setup.py，因此无法使用 pip 或 easy_install 进行安装
