PyQt5 - Failed to load platform plugin “windows”. Available platforms are: windows, minimal

Question

When I try to run any PyQt5 program from Eclipse, I got this error.

Failed to load platform plugin \"windows\". Available platforms are: windows, mini

Answer 1

This is what worked for me while using the Anaconda Python 3.6 distribution:

1. I installed PyQt5 using pip install pyqt5. What this does is it creates a Qt/Pluginsplugins directory in the ../Anaconda3/Lib/site-packages/PyQt5 path.

2. Following Roger Allen and uetoyo, I added:

if os.name == "nt":  # if windows
    from PyQt5 import __file__
    pyqt_plugins = os.path.join(os.path.dirname(__file__), "Qt", "plugins")
    QApplication.addLibraryPath(pyqt_plugins)
    os.environ['QT_QPA_PLATFORM_PLUGIN_PATH'] = pyqt_plugins

to my script. It works with pyinstaller as well.

Answer 2

Copy C:\Python34\Lib\site-packages\PyQt5\libEGL.dll to the same directory as your .exe.
