我收到此错误"Command 'openmC语言 p' returned non-zero exit status 255."

Question

我在macOS Catalina上使用openMC通过conda安装。此处为教程。此外，我使用Jupyter笔记本编写代码。然后我尝试了示例>gt；在此处张贴图片(_P(在之前我没有问题

ln[9]: plot = openmc.Plot.from_geometry(geometry)
plot.pixels = (250, 250)
plot.to_ipython_image()

我收到这个错误

所以我多次尝试重新安装，但都不起作用，请帮帮我。非常感谢

我认为您需要通过终端在操作系统上定义env变量OPENMC_CROSS_SECTIONS。

它在linux上对我有效，然而，我没有使用MACos的经验。
