Thank you for any and all advice.When I try to run it from there I get:. It's probably some conflict of libraries in your OS. Pulpo directory contains all required libraries include xcb support.
You have probably installed different version of Qt in your system and this library is wrongly used by Pulpo. Unfortunately, I don't know what is wrong there.
Paths are exactly the same like on our testing machine where everything works great. Obviously libXxcb was not found but trying to do apt-get install libXxcb gave me "Package can not be found".
So I decided to switch to my windows client to run pulpo from there but much to my surprise this is also not working. Extracting the zip files gives me some files, running the pulpo. I cannot see a subfolder "platforms" which is suggested and also no file qwindows.

So I followed the instructions and added a. Once I added qoffscreen. Whereas this wasn't enough in my case. I had also to add following line at the beginning of my main. The application is able to run on the host system, since the Qt bin path is in the system PATH variable. There is a standard Qt tool for deployment of Qt applications on Windows windeployqt to be able to run the application on target machines that do not have Qt installed. The simplest deployment:.
The tool windeployqt has various options. It can also take care about deployment of qml related files. Of course you can have also issues with MSVC redistributables, but those should be deployed separately and installed once per system.
Try it because both QtCreator and QT framework both have the same dlls and you must pinpoint the exact ones used. I copied all dlls needed in the same folder as the app. And the most important step in my case is to create a file named qt. This file should contain the path to the plugins. My qt. I had the same issue "Application failed to start because it could not find or load the QT platform plugin "windows" I fixed this by copying below files to the app. Note this issue can also be caused if the search path for qwindows.
Qt platform plugin issue -- What is this? Is it self-fixable by the common person?
Edit: Some people started to mark my question as a duplicate. Do not forget that many similar questions existed when I asked this one see e. However, none of these answers solved my problem. After a long search I found a comment which had been ignored by all users pointing to the missing lib. Now, many months later, the comment has been changed to an answer. However, when I answered this question by msyself I intended to help other people by directly providing the solution.
This should not be forgotten and so far my answer helped a lot of people. Therefore my question is definitely not a duplicate. By the way: The accepted answer within the provided link on top does not solve the problem! Failed to load platform plugin "windows". Available platforms are : Error. However, in my case the problem still persists.
I am using Qt 5. Application is compiled in "Release"-mode and can be executed if directly started with Qt Creator. This application failed to start because it could not find or load the Qt platform plugin "windows". Available platform plugins are: minimal, offscreen, windows. Does not matter if I rename it to "platform" as some other users did.How to Fix All .DLL file Missing Error in Windows PC (windows 10/8.1/7)
Qt is still not finding the "platform plugin windows", where is my mistake? The libEGL. I created a platforms directory next to my exe location and put qwindows.
I am getting the error "could not find or load the Qt platform plugin windows" while using matplotlib in PyCharm. I had the same problem with Anaconda3 4. When I tried to run a simple program that uses matplotlib, I got this error message:. After setting the variable you might need to restart PyCharm, if the change does not have an immediate effect.
Update: Even though after that the command line Python worked, TexWorks which uses Qt as well displayed an error message very much like it. I just needed to re-arrange the PATH entries. Dependency Walker is such a useful tool. I had a similar problem with PyCharm where things worked great in main run but not in debugger, getting the same error message. This happened for me because I had moved my Anaconda installation to a different directory.
The debugger goes and checks a qt. This location can be found by running import sys; print sys. I found this solution through a pile of web searches and it was buried deep here. The qt. If you want to visualize your matplotlibs in an alternative way, use a different backend that generates the graphs, charts etc.
Pycharm Console or Debugger showing this issue - Could not find or load the Qt platform plugin windows. Reason - Python exe file may be located at a different location for Pycharm interpreter, you might manually select it in file,settings,interpreter.
Set the working directory. Set it to parent directory where your all codes are present. I have found a solution that worked for me, follow the link given below. This solution includes a code snippet to add before you import any modules from Pyside2 or PyQt5 package.
This solution works for PyQt5 and PySide2 modules. However, I faced the same error log when I tried to run a bundled script exe.
With some shallow debug, it's evident that plugin folder itself is missing. I fixed the problem by adding the plugin folder in the appropriate location.

I had the same issue. Simply activating the Anaconda environment solved the issue. I had the same issue with Qt 5. What works in my case is:. Run from command prompt windeployqt.

Hello, I've been using Anaconda on Windows 10 for the past few months. However, today I tried launching the program and got the following error:. I read around about doing 'conda update -all' in cmd, however it didn't work for me, neither reinstalling Anaconda. This seems to be a common problem, however I can't seem to find a straightforward solution online, what can I do? Also, you say you have done conda update --allbut your Qt version states 5.
Last week we released version 5. The recent Anaconda I got this after my first ever install of 4. I opened Anaconda Prompt tried conda update qt as above and it complained it wasn't installed. So I tried conda install qt and it worked. I can now open the Navigator. I'll stay on that version until the bug is fixed, or change my username to a non ASCII name easier said than done.
Seconding the results from Staplegun above. Same problem here with conda 4. Opening Anaconda prompt and running conda update qt yielded a PackageNotFoundError but conda install qt solved it and I can run Navigator now. I installed Anaconda It has fixes for both the accented character and also for install locations longer than 30 characters. It is only a Miniconda though you can just conda install anaconda afterwards to make it an Anacondaand only the Python3 version works well in my testing at present.
It's very tricky to write non-ASCII-correct Python2 code, and even if we fix our own software condaconda-buildmenuinst etc then the software that our users subsequently install into that installation will often not work correctly, so I'm a bit torn about what to do about that.
My current opinion is that the safest thing to do is to advise people who want to do this not to use Python2, but I'd like to get a better understanding of how much stuff is broken first. It worked for me, thanks Serkan It does not work to me Serkan
