env: macbookpro

conda create -n gobigger python=3.6.8
conda activate gobigger
conda install -c opendilab gobigger

在环境下，报上述错误。请帮忙解决下吧

Temporary solution: Modify gobigger/render/env_render.py L218:

                font = pygame.font.SysFont('arial', max(font_size, 4), True)

to

                font = pygame.font.SysFont('arial', max(font_size, 10), True)

solved.

Thank you for opening this issue!

I am sorry but I can not reproduce this situation. Could you please give more details about it? Is there a game interface pop up? If it pops up, could you control the ball in the game? By the way, I don't think changing the font_size when calling pygame.font.SysFont() could help. Could you try to re-execute the start command with the original code?

We will also try to reproduce this situation. Hope you enjoy this game!

can reproduce this with latest pygame==2.0.3, downgrade to pygame==2.0.0 works fine.

Oh, thanks for your reply. I reproduce the error with pygame==2.0.3 and 2.0.2. And pygame==2.0.0 & 2.0.1 works fine. Thanks @wduo , we enlarge the font_size when calling pygame.font.SysFont() to avoid the pygame.error as a temporary solution #13. And we create a new issue in pygame repo . We will continue to pay attention to the solution to this problem.
