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

I like uetoyo's answer, but Anaconda has moved the directory. This works for me Python 3.5.2 Anaconda 4.2.0 on Windows 7.

import os
if os.name == "nt":  # if windows
    import PyQt5
    pyqt_plugins = os.path.join(os.path.dirname(PyQt5.__file__),
                                "..", "..", "..", "Library", "plugins")
    QApplication.addLibraryPath(pyqt_plugins)
