i installed pyside2 and pyqt5 using pip install

when i run qt creator i get:

/usr/lib64/qtcreator/plugins/libQbsProjectManager.so: Cannot load library /usr/lib64/qtcreator/plugins/libQbsProjectManager.so: (libqbscore.so.1.13: cannot open shared object file: No such file or directory)

when i run this:

import sys
import os
from PySide2.QtWidgets import QApplication, QLabel

os.environ['QT_DEBUG_PLUGINS'] = '1'

if __name__ == "__main__":
    app = QApplication(sys.argv)
    label = QLabel("Hello World")
    label.show()
    sys.exit(app.exec_())

I get:
