I declared victory last week after spending several hours battling with MacPorts and distutils. The downside, however, is that packaging PyQt applications so that they can be deployed to users on Windows and Mac OS X is an immensely frustrating and arcane process. NeuTomPy toolbox supports Linux, Windows and Mac OS 64-bit operating systems.Fortunately, there are cross-platform Python bindings for Qt. MacPorts is a package manager for Mac OS X that makes working with Unix utilities easier.Errors in Anaconda after pip install pyqt5 (or conda update spyder)Helpful.For Windows, I'm running XP in VirtualBox. My test applicationMy computing environment is a quad core Mac Pro configured to dual-boot OS X and openSUSE 11.1. The initial setup process for Mac OS X will require a lot of very heavy compilation, so you are going to be in for a world of pain and a very long wait if you try to do this on a Mac mini. The easiest way to accomplish this is to use a Mac and either triple-boot or virtualize Windows and Linux.
![]() I have published the complete source code of the program on Launchpad. The app has a few simple features like support for receiving images via drag-and-drop, and it can proportionally resize them before uploading.The program consists of one module of Python code which contains the application logic and a few basic user interface forms that I made with the Qt Designer program. The Ars CMS is built on Movable Type, which means that it supports the MetaWeblog XML-RPC API, and my app lets you upload images to any standard Movable Type or WordPress blog that supports the API. You'll want to get the Windows installer that is compatible with Python 2.6 it's listed at the bottom of the Binary Packages section.These components should be enough to give you a fully functional environment for running PyQt applications. Use the binary installer for Windows from the Python website.The next step is installing the Python bindings, which can be obtained from the download page at the PyQt website. Next, you will need to install Python 2.6.1. Start by downloading and installing the standard Qt SDK from the Qt Software website. AdvertisementTo build a distributable PyQt package for Windows, you first need to set up a working PyQt execution environment. An installer for py2exe is available from the SourceForge website.You will need to adapt your setup.py script so that it can provide proper instructions to py2exe. This is done with a utility called py2exe that leverages Python's distutils framework. These can be found in the site-packagesPyQt4examples folder.Now that you have a working PyQt environment, you need to package up the application so that you can distribute it to users and make it possible for them to run it without having to install all of the dependencies. There are several example scripts that come bundled with the PyQt installation. Pyw file in the file manager. If your PyQt environment installed correctly, you should be able to run the program by double-clicking the. The "windows" parameter specifies the script that py2exe should use to launch the actual program. The last two lines were added to accommodate py2exe. The following example shows my setup.py file: from distutils.core import setupAuthor="Ryan General Public License (GPL)",Options=)Most of that is pretty much standard distutils. Pyqt5 Zip File In OrderMy program dynamically loads the user interface description XML files at runtime, but it can't read those files when they are bundled up in the zip archive.When you are building PyQt applications with py2exe, you need to either statically generate your user interface modules from the XML description files in advance, disable archiving with the skip_archive option, or structure your program so that the UI files will not end up in the archive.After you finish making your setup.py script, you can build your redistributable package by running it from the command line: $ python setup.py py2exeThe terminal will display a lot of messages as it byte-compiles your modules and copies all of the necessary dll files and other dependency components. I disable that with the skip_archive option. AdvertisementThe py2exe tool will typically compress all of your required Python library modules into a single zip file in order to reduce space and keep your redistributable package clean. For PyQt applications, you will need to tell it to include sip, a fundamental component of the PyQt binding system. Send on behalf of office 365 for macThis package is available directly from Microsoft.Deploying PyQt on Windows works reasonably well. A lot of PyQt developers seem to like Inno Setup, a free installer maker.Although your users will not have to manually install Qt or the PyQt bindings, they might still have to install the VC++ 2008 Redistributable Package. It includes the executable and all of the runtime dependencies, which means that users will be able to run the program without having to install the other components.You can just zip it up and ship it out that way, but it will be more convenient for your users if you give them a single self-standing executable with a standard installer wizard. This adds up to roughly 25 MB for a simple program. If the script won't execute, make sure that Python is in your PATH environment variable.To deploy your application to users, ship them everything that is in the "dist" directory. ![]()
