我只找到了一些关于

ubuntu

的参考资料，上面说要安装

libsdl2 image dev

，但正如你看到的那样，我已经在安装它了。

Dockerfile不能产生错误消息：它是硬连接的，不能以很难覆盖的方式执行任何操作。您是如何启动该应用程序的？Docker中的图形应用程序充其量是棘手和挑剔的，您最好在没有Docker的Python虚拟环境中运行它。我想问题是在尝试启动刹车应用程序的图形界面时。为应用程序提供一个隔离的环境是一个好的做法？类似于conda？Python打包用户指南pipfile，但是任何基于Python虚拟环境的东西都可以很好地工作。是的，但我指的是可以在笔记本电脑之间轻松共享的东西，比如刚刚运行的dockerfile及其工作包
