macOS Open MPI+Fortran运行ExoPlaSim报错 求环境配置方案

我尝试在自己的MacBook上运行ExoPlaSim软件用例。该软件虽主要面向Linux平台开发，但根据开发者说明可在Mac系统上运行。我运行简单的默认测试用例脚本时出现了一长串报错，我个人推测（如有误请指正）报错的核心原因是Open MPI与Fortran环境适配存在问题。我自身缺乏足够的开发知识排查该问题，因此希望获得相关帮助。

核心报错信息 #

终端输出末尾的报错信息最具参考价值，指向Fortran/Open MPI相关问题：

During handling of the above exception, another exception occurred:

本地运行环境 #

• 系统版本：Big Sur 11.5
• 编译器：GNU Fortran/GCC 11.3.0
• Open MPI版本：4.1.4，通过brew安装，终端执行ompi_info命令可正常查询版本，已知该版本支持Fortran

Open MPI官方给出了新版Open MPI在OS X系统上的适配说明，受限于我的开发知识储备无法理解操作指引，也不确定该方案是否能解决我遇到的问题。

测试用例说明 #

我使用的是ExoPlaSim官方提供的基础测试用例Python脚本，内容如下：

import exoplasim as exo
mymodel = exo.Model(workdir="mymodel_testrun",modelname="mymodel",resolution="T21",layers=10,ncpus=8)
mymodel.configure()
mymodel.exportcfg()
mymodel.run(years=100,crashifbroken=True)
mymodel.finalize("mymodel_output")

该脚本不存在问题：其他用户可正常运行，也是软件开发者推荐的测试脚本。我仅寻求Mac端相关依赖库的安装、配置解决方案，该问题并非ExoPlaSim软件本身导致。
