Building with "UnicodeDecodeError" after porting to a new machine

[Jerry]

Dear All,
I am trying to port CESM2.1.3 to a HPC system.
After compiling and installing the required software libraries, I tried to run a test case with compset "B1850".
However, when executing case.build, an error related to 'UnicodeDecodeError' occurred.
The error occurs during the compilation of the land model component, so I upload the clm build log file.
By the way, When I tested with the G compset, the compilation passed.
And I also upload the config_machines.xml, config_compilers.xml and config_batch.xml.
As well as the loaded environment variables
export PATH=/public/home/amduan/CESM_Env/GNU/bin:/public/home/amduan/CESM_Env/OPENMPI/bin:$PATH
export LD_LIBRARY_PATH=/public/home/amduan/CESM_Env/GNU/lib64:/public/home/amduan/CESM_Env/OPENMPI/lib:/public/home/amduan/CESM_Env/OPENBLAS/lib:/public/home/amduan/CESM_Env/HDF5/lib:/public/home/amduan/CESM_Env/NETCDF/lib:/public/home/amduan/CESM_Env/PNETCDF/lib:$LD_LIBRARY_PATH
export NETCDF=/public/home/amduan/CESM_Env/NETCDF
export HDF5=/public/home/amduan/CESM_Env/HDF5

export PNETCDF=/public/home/amduan/CESM_Env/PNETCDF
module load python/3.8.1 cmake/3.15

You should first update to the latest release in the 2.1.x series - 2.1.5 I believe that the Unicode error is due to a python version mismatch that should be solved in 2.1.5.

Hi, Jedwards. Thanks for your reply.
The python version I use is 3.8.1.
Can I solve the error by changing python's version?

You can solve the error in a supported way by updating to cesm2.1.5. You can also solve this issue by using python 2.7 but this is not a supported or recommended solution.
