Description
this application failed to start because it could not find or load the Qt platform plugin "windows" in "".
Reinstalling the application may fix this problem.
Reason (Lib/site-packages/PySide2/_init_.py):
_utils.register_qt_conf(prefix=prefix,
binaries=prefix,
plugins=prefix+"/plugins",
imports=prefix+"/imports", #Compile the generated PySide2 package without the "imports" directory
translations=prefix+"/translations")
Solution (Lib/site-packages/PySide2/_utils.py):
def register_qt_conf(prefix, binaries, plugins, imports, translations, force=False): """ Register qt.conf in Qt resource system to override the built-in configuration variables, if there is no default qt.conf in executable folder and another qt.conf is not already registered in Qt resource system. """ try: from . import QtCore except ImportError: return # Check folder structure if not prefix or not os.path.exists(prefix): if force: raise RuntimeError("Invalid prefix path specified: %s" % prefix) else: return if not binaries or not os.path.exists(binaries): if force: raise RuntimeError("Invalid binaries path specified: %s" % binaries) else: return else: # Check if required Qt libs exists in binaries folder if sys.platform == 'win32': pattern = ["Qt5Core*.dll"] else: pattern = ["libQtCore.so.*"] if not _dir_contains(binaries, pattern): if force: raise RuntimeError("QtCore lib not found in folder: %s" % \ binaries) else: return if not plugins or not os.path.exists(plugins): if force: raise RuntimeError("Invalid plugins path specified: %s" % plugins) else: return if not imports or not os.path.exists(imports): if force: raise RuntimeError("Invalid imports path specified: %s" % imports) #else: #Comment this line #return #Comment this line
