I am trying to build JEDI-SKYLAB 5.0 in my institutes HPC which is not included in preconfigured sites. The OS in this HPC is CentOS Linux release 7.9.2009. Before build JEDI, I am trying to build spack-stack environment following the instruction below.

[https://spack-stack.readthedocs.io/en/latest/NewSiteConfigs.html#prerequisites-red-hat-centos-8-one-off](https://spack-stack.readthedocs.io/en/latest/NewSiteConfigs.html#prerequisites-red-hat-centos-8-one-off)

The modules I loaded for this task are:  
cmake/3.26.3 gcc/11.3.0  
ompi/4.1.5/gnu-11.3.0  
bzip2/1.0.6  
texlive  
tcltk/8.4.19  
python3/3.9.3\_anaconda2021.11\_mamba

I was able to installed it sucessfully but when I run command ‘spack stack setup-meta-modules’ then I got an error.

The error is :

> Error: local variable ‘package\_name’ referenced before assignment

I am copying the log output here:

It looks like you’ve hit a bug in the script! I noticed that you don’t have an MPI provider listed:

```auto
Parsing spack environment package config …
… list of possible compilers: ‘[‘gcc@11.3.0’, ‘gcc’, ‘intel’, ‘pgi’, ‘clang’, ‘xl’, ‘nag’, ‘fj’, ‘aocc’]’
… list of possible mpi providers: ‘[‘openmpi@4.1.5’, ‘openmpi’, ‘mpich’]’
[‘gcc’, ‘Core’, ‘module-index.yaml’]
… stack compilers: ‘{‘gcc’: [‘11.3.0’, ‘11.3.0’]}’
… stack mpi providers: ‘{}’
… core compilers: [‘gcc@4.6’]

```

That means the MPI provider listed in your packages.yaml (openmpi@4.1.5?) doesn’t match the one that spack-stack used. With the env activated, can you run `spack find` and look for what could be the MPI library?

Also, please head to [GitHub - JCSDA/spack-stack](https://github.com/jcsda/spack-stack) and create an issue there with the detailed description that you posted above.

Thanks!
