[IndexError] invalid index to scalar variable

[asaksager]

I get the following error IndexError: invalid index to scalar variable., when I run the
arcasHLA reference --version 3.24.0 -v

The installation:
copied and changed the environment.yml file from github as I am using a Mac M1.

• samtools==1.30
• kallisto==0.51.0
  samtools and kallisto versions not found #137 (comment)

$ conda env create -n env-arcashla -f environment.yml

$ conda activate env-arcashla

$ conda install arcas-hla -c bioconda -c conda-forge

I could see this has previously been an issue, but it does not seem to have been fixed fully: #116 (comment)

Here is the full output:

	You are in 'detached HEAD' state. You can look around, make experimental
	changes and commit them, and you can discard any commits you make in this
	state without impacting any branches by switching back to a branch.
	
	If you want to create a new branch to retain commits you create, you may
	do so (now or later) by using -c with the switch command. Example:
	
	  git switch -c <new-branch-name>
	
	Or undo this operation with:
	
	  git switch -
	
	Turn off this advice by setting config variable advice.detachedHead to false
	
	HEAD is now at c5acf7a4 Update to hla.dat
