this is my code which I am running on a Python 3 on Repl.it, unfortunately when I try and use the Tkinter module to create a window, it can't seem to find a display environment. Why is this and is there a fix for it?

推荐答案

不幸的是，我不相信您可以在 repl.it 上配置它，如果可以，我认为这不值得麻烦.尝试在本地运行您的程序.

Unfortunately, I don't believe you can configure this on repl.it, and if you could, I don't think it would be worth the hassle. Try running your program locally.

让我试着用一个例子来回答这个问题.

Let me try and answer this with an example.

$DISPLAY 环境变量用于指向您在 PC 上运行的任何 X 服务器应用程序.tkinter 将查看您的 $DISPLAY 变量以启动 X 服务器应用程序(它将启动用于图形界面的 X11 协议).

The $DISPLAY environment variable is used to point to any X-server applications you have running on your PC. tkinter will look to your $DISPLAY variable to launch the X-server application (which in turn will launch the X11 protocol used for graphical interfaces).
