因为想跨平台，所以考虑Qt，又想结合脚本的便捷。考虑PyQt

网上搜索了一下，资料挺少的。有的还是以前的资料。

参考这里 http://www.noktec.be/python/how-to-install-pyqt4-on-osx

1:下载安装Qt

http://qt-project.org/downloads

我下载的是Qt 5.0.2 for Mac (404 MB) (Info)

安装起来还挺方便的。不说了

2：下载SIP

http://www.riverbankcomputing.co.uk/software/sip/download

我下载的是 sip-4.14.7-snapshot-bd9eccac4407.tar.gz

下载以后解压

cd sip-4.14.7-snapshot-bd9eccac4407python configure.py -d /Library/Python/2.7/site-packages --arch=i386makesudo make install

安装起来没问题。

3：下载PyQt4

http://www.riverbankcomputing.co.uk/software/pyqt/download

我下载的是 PyQt-mac-gpl-snapshot-4.10.2-ffcf323516fc.tar.gz

下载后解压安装配置这里要参考改版后的配置文档，新版本用的是configure-ng.py：

http://pyqt.sourceforge.net/Docs/PyQt4/installation.html#configuring-pyqt4

命令

cd PyQt-mac-gpl-snapshot-4.10.2-ffcf323516fcpython configure-ng.py -q /Users/watsy/Qt5.0.2/5.0.2/clang_64/bin/qmake -d /Library/Python/2.7/site-packages/ --sip /System/Library/Frameworks/Python.framework/Versions/2.7/bin/sipmakesudo make install

以上步骤完成以后，运行demo

#!/usr/bin/python# -*- coding: utf-8 -*-"""ZetCode PyQt4 tutorial In this example, we create a simplewindow in PyQt4.author: Jan Bodnarwebsite: zetcode.com last edited: October 2011"""import sysfrom PyQt4 import QtGuidef main():    app = QtGui.QApplication(sys.argv)    w = QtGui.QWidget()    w.resize(250, 150)    w.move(300, 300)    w.setWindowTitle('Simple')    w.show()        sys.exit(app.exec_())if __name__ == '__main__':    main()

执行得到如下错误

Traceback (most recent call last):  File "pyqtDemo.py", line 16, in <module>    from PyQt4 import QtGuiImportError: dlopen(/Library/Python/2.7/site-packages/sip.so, 2): no suitable image found.  Did find:/Library/Python/2.7/site-packages/sip.so: mach-o, but wrong architecture

在考虑是什么问题

查看

lipo -info /Library/Python/2.7/site-packages/sip.so

得到

Non-fat file: /Library/Python/2.7/site-packages/sip.so is architecture: i386

想来现在机器用的是64位系统了。

修改 sip的配置从新编译

cd sip-4.14.7-snapshot-bd9eccac4407python configure.py -d /Library/Python/2.7/site-packages --arch=x86_64makesudo make install

安装碗以后运行demo

perfect~
