Question

我在 Mac M1 上玩 Pygame。发生的事情是 Pygame 不允许我使用字体模块。查看一些 GitHub 讨论，我尝试使用 brew 安装 sdl2 库，但没有任何效果。我该如何解决这个问题？

P.S 虽然代码没有错误我还是会提供的。

我相信这已在 Github 上的当前 pygame main 中修复，通过此拉取请求：https://github.com/pygame/pygame/pull/2636。

您应该这样做：

在本地克隆 pygame 存储库，导航到它。
# scraping the foursquare website for the information we want and obtaining the json file as results for i, series in df_income_zip_good.iterrows(): lat = series ['lat'] lng = series ['lng'] town = series ['place'] LIMIT = 100 radius = 1000 url4Sqr = 'https://api.foursquare.com/v2/venues/explore?&client_id={}&client_secret={}&v={}&ll={},{}&radius={}&limit={}'.format( CLIENT_ID, CLIENT_SECRET, VERSION, lat, lng, radius, LIMIT) #export results to json file result4Sqr = requests.get(url4Sqr).json()["response"]['groups'][0]['items'] #print results from call print (result4Sqr)
brew install sdl2 sdl2_gfx sdl2_image sdl2_mixer sdl2_net sdl2_ttf
brew install Caskroom/cask/xquartz

导入错误：无法从部分初始化的模块 'pygame.font' 导入名称 'Font'（很可能是由于循环导入）
