kivy-designer is not launching

[mthnglac]

Hi guys,

I'm using a kivy over pycharm. I want to install a kivy designer to take advantage of Kivy's visual interface features. I installed the kivydesigner as written in the document with python3 but when I run it, I get an error like the following below ; the popup comes on the screen and closes immediately.

Thank you in advance for your help.
