python - pygame.error : video system not initialized when trying to run examples

Question

我正在尝试学习如何使用 pygame，但我在运行它时遇到了问题。我按照这里的说明安装了它 https://www.pygame.org/wiki/GettingStarted .

他们告诉你安装它

python3 -m pip install -U pygame --user

然后用

python3 -m pygame.examples.aliens

我在 Ubuntu 中运行了这些命令并成功安装了 pygame。但是，当我尝试运行示例时，我得到

要运行 linux 版本，您需要一个真正的 linux 系统，使用 X11 服务器来显示窗口——我认为这不适用于 windows 子系统。另一种选择是使用python for windows并直接在windows中安装pygame
