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file时，出现了此错误。

Solving linear variational problem. Traceback (most recent call last): 
File "ft01_poisson.py", line 39, in <module> plot(u) File "/usr/lib
/python3/dist-packages/dolfin/common/plotting.py", line 438, in plot 
return _plot_matplotlib(object, mesh, kwargs) File "/usr/lib/python3/dist-packages/dolfin/common/plotting.py", line 281, in _plot_matplotlib

这是什么问题？

我也有一些问题，无法轻松在ubunto终端上打开Windows文件。有没有简单的方法可以做到这一点？

您是否看过调试错误？该错误发生在文件ft01_poisson.py中，并带有错误消息：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。该错误消息还表明您需要设置$ DISPLAY环境变量。您可以使用Python库：https://docs.python.org/3/library/os.html#os.environ查看您的环境变量。
