In this article, we will be looking at the stepwise procedure to install the PyQt for python in Windows. PyQt is free software developed by the British firm Riverbank Computing. Here, the user can simply run the below command in the command prompt or the power shell of the windows to verify if the python is already installed in the system or not.
If python is already installed in the system the output of the command will be the running version of python and if not installed it will produce an error. In case if python is not installed the user can refer to How to Install Python. Command to check if python is already installed: python --version Output: Step 2: Verify that PyQt is not installed before: In this, the user has to simply type the below command to verify if the PyQt is not installed before, if installed the user has no need to follow the below steps mentioned.
Command: pip list Output:. Skip to content. In the last article , I introduced you to Qt and its Python interfaces, PyQt and PySide; now that you know a bit about them, pick one and install it. I recommend PySide for two reasons: first, this tutorial is conceived in terms of PySide, and may cover a few topics that are less fully-implemented in PyQt; and second, its licensing is more flexible for your future use.
Either one will work, however. Binary installers are available for most common platforms; links and setup instructions are outlined below:. For PySide, get the appropriate binary for your version of Python from releases. To recall it, it requires to install first of all the pip and virtualenv modules to create a virtual environment for python where it will be installed.
Then, it follows similarly to Peter Du answer. However, I would like to emphasize in the configuration options:. Another point to highlight is the version. I have probed with the latest version of SIP 4. I've tried also with the SIP 4. Finally, I achieved to install it and launch successfully with SIP 4. If you want to run standalone applications which uses PyQt5 installed by this method, from a conventional CMD, you have two options:.
Thank you for your interest in this question. Update: I installed Qt 5. Determining the details of your Qt installation Error: Failed to determine the detail of your Qt installation.
Try again using the --verbose flag to see more detail about the problem. And when I execute the command python configure. All rights reserved. EXE"' : return code '0xc' Stop. Improve this question.

I installed QT and now I get another error: 'nmake' is not recognized as an internal command.
How to fix this? I think that while you've added nmake. What worked for me was to run all of the commands from the Visual Studio Command Prompt.
This will set all the necessary environment variables automatically. Add a comment. Active Oldest Votes. Mainly I use the following command under the cmd pip install pyqt5 And it works with no problem! Improve this answer. Malek B. I installed pyqt5 using pip without any issues.
I'd also add the run your command prompt as administrator, you'll likely get some File Permission errors otherwise. Although not explicitly stated I would assume OP is using py2 and mostly only py2 users will land here. Consider this a suggestion to upgrade to py3 : — NirIzr. I'm using Python3 and I landed here and I'm glad I read this answer before trying anything stupid Although on Windows this leads to "Successfully installed PyQt5-sip Show 2 more comments.

The binary packages for Windows definitely seem to be the best bet. All of the examples that load QML seem to just open an empty white window. Installing that download fixed that issue well a few pure OpenGL examples don't work, because they use PyOpenGL which I don't have working on my system.
