问题 I am trying to download kivy module using pip . When I run the pip install command , I got an error: Could not install packages due to an EnvironmentError: [Errno 42] Illegal byte sequence. I already re-installed python , I am running as an administrator and I also tried to download via the wheel file. All of the above causes the same environment error. 回答1: There seems to be a bug in pip https://github.com/pypa/pip/issues/5665. The current workaround is to run the command in silent mode pip

Kivy: accessing a method on a different class

由 走远了吗. 提交于 2020-02-23 03:50:11
问题 Let's pretend I am building a tic-tac-toe game (becouse it's pretty similar as a structure) I want the result to be shown in a popup, with a new game button, and I want this popup to let me access settings (with another button) and change them, always staying within the popup, then leave and finally close it and start a new game. I wish i could keep things ordered and therefore have a separate popup class where i can build my custom popup. I have the newgame method and reset method as method

How to dismiss the Kivy pop-up via a Button?

由 徘徊边缘 提交于 2020-02-08 07:14:06
问题 I have a pop-up created with Kivy, which contains 2 buttons. User can dismiss the pop-up by pressing outside of the pop-up area (auto_dismiss = True), or by clicking the "No" button.
