windows子系统for linux for fenics程序上的python3出错

Question

我刚开始在windows子系统ubuntu上的python3中使用fenics，当我打开第一个titurial file时，我得到了这个错误。在

有什么问题吗？在

在ubunto终端上打开windows文件也有一些问题。有什么简单的方法吗？在

你看过调试错误了吗？错误发生在文件：ft01_poisson.py，同时出现错误消息：TclError: no display name and no $DISPLAY environment variable

似乎您正在调用另一个python脚本，您需要从那里开始调试，而不仅仅是错误消息。错误消息还建议您需要设置$DISPLAY环境变量。您可以使用Python库：https://docs.python.org/3/library/os.html#os.environ查看环境变量。在
