pg.event.set_allowed([pg.KEYDOWN，pg.KEYUP，pg.QUIT]) pygame.error:视频系统未初始化

Question

运行马里奥游戏时在此文件中出错我从以下链接(https://github.com/Ja1r0/DQN-play-SuperMario)下载了代码当尝试运行文件super_mario.py时，我得到了上面的错误(pygame.error视频系统未初始化)。

我正在使用windows10中的ubuntu18.04小部件。

import platform

p_name = platform.system()
print(p_name)

import os
import pygame as pg

ORIGINAL_CAPTION = c.ORIGINAL_CAPTION

current_dir = os.path.dirname(os.path.realpath(__file__))
'''
os.environ['SDL_VIDEO_CENTERED'] = '1'
pg.init()
pg.event.set_allowed([pg.KEYDOWN, pg.KEYUP, pg.QUIT])
pg.display.set_caption(c.ORIGINAL_CAPTION)
SCREEN = pg.display.set_mode(c.SCREEN_SIZE, 0, 32)
SCREEN_RECT = SCREEN.get_rect()
FONTS = tools.load_all_fonts(os.path.join("resources", "fonts"))
MUSIC = tools.load_all_music(os.path.join("resources", "music"))
GFX = tools.load_all_gfx(os.path.join("resources", "graphics"))
SFX = tools.load_all_sfx(os.path.join("resources", "sound"))
# dev env

您说您使用的是[the] ubuntu 18.04 widget in windows10 (我猜您说的是Linux的Windows子系统)，它没有视频显示。它只在控制台上运行，除非你安装了X-server，比如xming。

error video system not initialized确切地告诉您:没有视频系统可以绘制可用的窗口。

因此，您可以尝试安装X-server或从Windows10安装中运行代码，而不是从WSL中运行。
