I'm following this tutorial to try and install Spack on a large cluster running CentOS 7.
At the bootstrapping step spack spec zlib I get an error:
==> Error: <unknown file>:1: [ordereddict([('compiler', ordereddict([('spec', 'gcc@=4.8.5'), ('paths', ordereddict([('cc', '/bin/gcc'), ('cxx', '/bin/g++'), ('f77', '/bin/gfortran'), ('fc', '/bin/gfortran')])), ('flags', ordereddict()), ('operating_system', 'centos7'), ('target', 'x86_64'), ('modules', []), ('environment', ordereddict()), ('extra_rpaths', [])]))])] is not of type 'object'
I tried different Spack versions. I'm using default settings for the compilers, tried writing compilers.yaml, and set up a clean install multiple times. While spack list works, spack compiler find throws the same error. The compiler settings in this error are correct.
Can't find this error anywhere. Any help is highly appreciated!
